Taiwanese company QNAP has released updates to remediate a critical security flaw affecting its network-attached storage (NAS) devices that could lead to arbitrary code injection. Tracked as  CVE-2022-27596 , the vulnerability is rated 9.8 out of a maximum of 10 on the CVSS scoring scale. It affects QTS 5.0.1 and QuTS hero h5.0.1. "If exploited, this vulnerability allows remote attackers to inject malicious code," QNAP  said  in an advisory released Monday. The exact technical specifics surrounding the flaw are unclear, but the NIST National Vulnerability Database (NVD) has categorized it as an SQL injection vulnerability. This means an attacker could send specially crafted SQL queries such that they could be weaponized to bypass security controls and access or alter valuable information. "Just as it may be possible to read sensitive information, it is also possible to make changes or even delete this information with a SQL injection attack," according to  MI

VMware on Tuesday released software to remediate four security vulnerabilities affecting  vRealize Log Insight  (aka Aria Operations for Logs) that could expose users to remote code execution attacks. Two of the flaws are critical, carrying a severity rating of 9.8 out of a maximum of 10, the virtualization services provider noted in its first security bulletin for 2023. Tracked as CVE-2022-31706 and CVE-2022-31704, the directory traversal and broken access control issues could be exploited by a threat actor to achieve remote code execution irrespective of the difference in the attack pathway. "An unauthenticated, malicious actor can inject files into the operating system of an impacted appliance which can result in remote code execution," the company  said  of the two shortcomings. A third vulnerability relates to a deserialization flaw (CVE-2022-31710, CVSS score: 7.5) that could be weaponized by an unauthenticated attacker to trigger a denial-of-service (DoS) conditi

Over the past two years, a shocking  51% of organizations surveyed in a leading industry report have been compromised by a cyberattack.  Yes, over half.  And this, in a world where enterprises deploy  an average of 53 different security solutions  to safeguard their digital domain.  Alarming? Absolutely. A recent survey of CISOs and CIOs, commissioned by Pentera and conducted by Global Surveyz Research, offers a quantifiable glimpse into this evolving battlefield, revealing a stark contrast between the growing risks and the tightening budget constraints under which cybersecurity professionals operate. With this report, Pentera has once again taken a magnifying glass to the state of pentesting to release its annual report about today's pentesting practices. Engaging with 450 security executives from North America, LATAM, APAC, and EMEA—all in VP or C-level positions at organizations with over 1,000 employees—the report paints a current picture of modern security validation prac

Vulnerability analysis results in  Orange Cyberdefenses' Security Navigator  show that some vulnerabilities first discovered in 1999 are still found in networks today. This is concerning. Age of VOC findings Our Vulnerability Scans are performed on a recurring basis, which provides us the opportunity to examine the difference between when a scan was performed on an Asset, and when a given finding on that Asset was reported. We can call that the finding 'Age'. If the findings first reported are not addressed, they will occur in more scans over time with increasing Age, and so we can track how the Age of reported findings changes over time. As the chart below clearly illustrates, the majority of real findings in our dataset, across all Severity levels, are between 75 and 225 days old. There is a second 'peak' at around 300 days, which we suspect has more to do with the age of the data in the dataset and can therefore be ignored. Finally, there is a fascinating 

A suspected China-nexus threat actor exploited a recently patched vulnerability in Fortinet FortiOS SSL-VPN as a zero-day in attacks targeting a European government entity and a managed service provider (MSP) located in Africa. Telemetry evidence gathered by Google-owned Mandiant indicates that the exploitation occurred as early as October 2022, at least nearly two months before fixes were released. "This incident continues China's pattern of exploiting internet facing devices, specifically those used for managed security purposes (e.g., firewalls, IPS\IDS appliances etc.)," Mandiant researchers  said  in a technical report. The attacks entailed the use of a sophisticated backdoor dubbed  BOLDMOVE , a Linux variant of which is specifically designed to run on Fortinet's FortiGate firewalls. The intrusion vector in question relates to the exploitation of  CVE-2022-42475 , a heap-based buffer overflow vulnerability in FortiOS SSL-VPN that could result in unauthenti

A new critical remote code execution (RCE) flaw discovered impacting multiple services related to Microsoft Azure could be exploited by a malicious actor to completely take control of a targeted application. "The vulnerability is achieved through  CSRF  (cross-site request forgery) on the ubiquitous SCM service Kudu," Ermetic researcher Liv Matan  said  in a report shared with The Hacker News. "By abusing the vulnerability, attackers can deploy malicious ZIP files containing a payload to the victim's Azure application." The Israeli cloud infrastructure security firm, which dubbed the shortcoming  EmojiDeploy , said it could further enable the theft of sensitive data and lateral movement to other Azure services. Microsoft has since fixed the vulnerability as of December 6, 2022, following responsible disclosure on October 26, 2022, in addition to awarding a bug bounty of $30,000. The Windows maker  describes  Kudu as the "engine behind a number of feat

The maintainers of the  Git  source code version control system have released updates to remediate two critical vulnerabilities that could be exploited by a malicious actor to achieve remote code execution. The flaws, tracked as  CVE-2022-23521  and  CVE-2022-41903 , impacts the following versions of Git: v2.30.6, v2.31.5, v2.32.4, v2.33.5, v2.34.5, v2.35.5, v2.36.3, v2.37.4, v2.38.2, and v2.39.0. Patched versions include v2.30.7, v2.31.6, v2.32.5, v2.33.6, v2.34.6, v2.35.6, v2.36.4, v2.37.5, v2.38.3, and v2.39.1. X41 D-Sec security researchers Markus Vervier and Eric Sesterhenn as well as GitLab's Joern Schneeweisz have been credited with reporting the bugs. "The most severe issue discovered allows an attacker to trigger a heap-based memory corruption during clone or pull operations, which might result in code execution," the German cybersecurity company  said  of CVE-2022-23521. CVE-2022-41903, also a critical vulnerability, is triggered during an archive operatio

Users of Zoho ManageEngine are being urged to patch their instances against a critical security vulnerability ahead of the release of a proof-of-concept ( PoC ) exploit code. The issue in question is  CVE-2022-47966 , an unauthenticated remote code execution vulnerability affecting several products due to the use of an outdated third-party dependency, Apache Santuario. "This vulnerability allows an unauthenticated adversary to execute arbitrary code," Zoho  warned  in an advisory issued late last year, noting that it affects all ManageEngine setups that have the SAML single sign-on (SSO) feature enabled, or had it enabled in the past. Horizon3.ai has now released Indicators of Compromise (IOCs) associated with the flaw, stating that it was able to successfully reproduce the exploit against ManageEngine ServiceDesk Plus and ManageEngine Endpoint Central products. "The vulnerability is easy to exploit and a good candidate for attackers to 'spray and pray' acr

A majority of internet-exposed Cacti servers have not been patched against a recently patched critical security vulnerability that has come under active exploitation in the wild. That's according to attack surface management platform Censys, which  found  only 26 out of a total of 6,427 servers to be running a  patched version  of Cacti (1.2.23 and 1.3.0). The  issue  in question relates to  CVE-2022-46169  (CVSS score: 9.8), a combination of authentication bypass and command injection that enables an unauthenticated user to execute arbitrary code on an affected version of the open-source, web-based monitoring solution. Details about the flaw, which impacts versions 1.2.22 and below, were first revealed by SonarSource. The flaw was reported to the project maintainers on December 2, 2022. "A hostname-based authorization check is not implemented safely for most installations of Cacti," SonarSource researcher Stefan Schiller  noted  earlier this month, adding "uns

Cisco has warned of two security vulnerabilities affecting end-of-life (EoL) Small Business RV016, RV042, RV042G, and RV082 routers that it said will not be fixed, even as it acknowledged the public availability of proof-of-concept (PoC) exploit. The  issues  are rooted in the router's web-based management interface, enabling a remote adversary to sidestep authentication or execute malicious commands on the underlying operating system. The most severe of the two is CVE-2023-20025 (CVSS score: 9.0), which is the result of improper validation of user input within incoming HTTP packets. A threat actor could exploit it remotely by sending a specially crafted HTTP request to vulnerable routers' web-based management interface to bypass authentication and obtain elevated permissions. The lack of adequate validation is also the reason behind the second flaw tracked as CVE-2023-20026 (CVSS score: 6.5), permitting an attacker with valid admin credentials to achieve root-level privi

A zero-day vulnerability in FortiOS SSL-VPN that Fortinet addressed last month was exploited by unknown actors in attacks targeting governments and other large organizations. "The complexity of the exploit suggests an advanced actor and that it is highly targeted at governmental or government-related targets," Fortinet researchers  said  in a post-mortem analysis published this week. The attacks entailed the exploitation of  CVE-2022-42475 , a heap-based buffer overflow flaw that could enable an unauthenticated remote attacker to execute arbitrary code via specifically crafted requests. The infection chain analyzed by the company shows that the end goal was to deploy a generic Linux implant modified for FortiOS that's equipped to compromise Fortinet's intrusion prevention system ( IPS ) software and establish connections with a remote server to download additional malware and execute commands. Fortinet said it was unable to recover the payloads used in the subse

Details have emerged about a now-patched vulnerability in Google Chrome and Chromium-based browsers that, if successfully exploited, could have made it possible to siphon files containing confidential data. "The issue arose from the way the browser interacted with  symlinks  when processing files and directories," Imperva researcher Ron Masas  said . "Specifically, the browser did not properly check if the symlink was pointing to a location that was not intended to be accessible, which allowed for the theft of sensitive files." Google characterized the medium-severity issue (CVE-2022-3656) as a case of insufficient data validation in File System,  releasing   fixes  for it in versions 107 and 108 released in October and November 2022. Dubbed SymStealer, the vulnerability, at its core, relates to a type of weakness known as symbolic link (aka symlink) following, which  occurs  when an attacker abuses the feature to bypass the file system restrictions of a progra

Twitter on Wednesday said that its investigation found "no evidence" that users' data sold online was obtained by exploiting any security vulnerabilities in its systems. "Based on information and intel analyzed to investigate the issue, there is no evidence that the data being sold online was obtained by exploiting a vulnerability of Twitter systems," the company  said  in a statement. "The data is likely a collection of data already publicly available online through different sources." The disclosure comes in the wake of  multiple   reports  that Twitter data belonging to millions of users – 5.4 million in November 2022, 400 million in December 2022, and 200 million last week – have been made available for sale on online criminal forums. The social media giant further said the breach "could not be correlated with the previously reported incident, nor with any new incident," adding no passwords were exposed. The two datasets published in

UPDATE: CVE-2022-23529 Retracted Following Review Auth0 and Unit 42 said they are formally retracting CVE-2022-23529 (CVSS score: 7.6) based on the fact that several prerequisites are essential for exploitation. The cybersecurity company said "important security checks" have been added to fix the problem. "The security issue remains a concern only when the jsonwebtoken library is used in an insecure way," the maintainers said in an advisory. "In such a scenario, if all the prerequisites are met, the issue may be exploitable; however, the source of this risk is the calling code and not the library itself." A high-severity security flaw has been disclosed in the open source jsonwebtoken (JWT) library that, if successfully exploited, could lead to remote code execution on a target server. "By exploiting this  vulnerability , attackers could achieve remote code execution (RCE) on a server verifying a maliciously crafted JSON web token (JWT) reques

Fortinet has warned of a high-severity flaw affecting multiple versions of FortiADC application delivery controller that could lead to the execution of arbitrary code. "An improper neutralization of special elements used in an OS command vulnerability in FortiADC may allow an authenticated attacker with access to the web GUI to execute unauthorized code or commands via specifically crafted HTTP requests," the company  said  in an advisory. The vulnerability, tracked as CVE-2022-39947 (CVSS score: 8.6) and internally discovered by its product security team, impacts the following versions - FortiADC version 7.0.0 through 7.0.2 FortiADC version 6.2.0 through 6.2.3 FortiADC version 6.1.0 through 6.1.6 FortiADC version 6.0.0 through 6.0.4 FortiADC version 5.4.0 through 5.4.5 Users are recommended to upgrade to FortiADC versions 6.2.4 and 7.0.2 as and when they become available. The  January 2023 patches  also address a number of command injection vulnerabilities in Fo

Samba has released software updates to remediate multiple vulnerabilities that, if successfully exploited, could allow an attacker to take control of affected systems. The high-severity flaws, tracked as  CVE-2022-38023, CVE-2022-37966, CVE-2022-37967, and CVE-2022-45141 , have been patched in versions 4.17.4, 4.16.8 and 4.15.13  released  on December 15, 2022. Samba is an open source Windows interoperability suite for Linux, Unix, and macOS operating systems that offers file server, printing, and Active Directory services. A brief description of each of the weaknesses is below - CVE-2022-38023  (CVSS score: 8.1) - Use of weak RC4-HMAC Kerberos encryption type in the  Netlogon Secure Channel   CVE-2022-37966  (CVSS score: 8.1) - An elevation of privilege vulnerability in Windows Kerberos RC4-HMAC CVE-2022-37967  (CVSS score: 7.2) - An elevation of privilege vulnerability in Windows Kerberos CVE-2022-45141  (CVSS score: 8.1) - Use of RC4-HMAC encryption when issuing Kerberos t

Microsoft has revised the severity of a security vulnerability it originally  patched in September 2022 , upgrading it to "Critical" after it emerged that it could be exploited to achieve remote code execution. Tracked as  CVE-2022-37958  (CVSS score: 8.1), the flaw was previously described as an  information disclosure vulnerability  in SPNEGO Extended Negotiation ( NEGOEX ) Security Mechanism. SPNEGO, short for Simple and Protected GSSAPI Negotiation Mechanism (SPNEGO), is a scheme that allows a client and remote server to arrive at a consensus on the choice of the protocol to be used (e.g., Kerberos or NTLM) for authentication. But a  further analysis  of the flaw by IBM Security X-Force researcher Valentina Palmiotti found that it could allow remote execution of arbitrary code, prompting Microsoft to reclassify its severity. "This vulnerability is a pre-authentication remote code execution vulnerability impacting a wide range of protocols," IBM  said  this

Web applications, often in the form of Software as a Service (SaaS), are now the cornerstone for businesses all over the world. SaaS solutions have revolutionized the way they operate and deliver services, and are essential tools in nearly every industry, from finance and banking to healthcare and education.  Most startup CTOs have an excellent understanding of how to build highly functional SaaS businesses but (as they are not cyber security professionals) need to gain more knowledge of how to secure the web application that underpins it.  Why test your web applications?  If you are a CTO at a SaaS startup, you are probably already aware that just because you are small doesn't mean you're not on the firing line. The size of a startup does not exempt it from cyber-attacks – that's because hackers constantly scan the internet looking for flaws that they can exploit. Additionally, it takes only one weakness, and your customer data could end up on the internet. It takes ma

The U.S. National Security Agency (NSA) on Tuesday  said  a threat actor tracked as APT5 has been actively exploiting a zero-day flaw in Citrix Application Delivery Controller (ADC) and Gateway to take over affected systems. The critical remote code execution vulnerability, identified as  CVE-2022-27518 , could allow an unauthenticated attacker to execute commands remotely on vulnerable devices and seize control. Successful exploitation, however, requires that the Citrix ADC or Citrix Gateway appliance is configured as a SAML service provider (SP) or a SAML identity provider (IdP). The following supported versions of Citrix ADC and Citrix Gateway are affected by the vulnerability - Citrix ADC and Citrix Gateway 13.0 before 13.0-58.32 Citrix ADC and Citrix Gateway 12.1 before 12.1-65.25 Citrix ADC 12.1-FIPS before 12.1-55.291 Citrix ADC 12.1-NDcPP before 12.1-55.291 Citrix ADC and Citrix Gateway versions 13.1 are not impacted. The company also said there are no workarounds a

A critical security flaw has been disclosed in Amazon Elastic Container Registry (ECR) Public Gallery that could have been potentially exploited to stage a multitude of attacks, according to cloud security firm Lightspin. "By exploiting this vulnerability, a malicious actor could delete all images in the Amazon ECR Public Gallery or update the image contents to inject malicious code," Gafnit Amiga, director of security research at Lightspin, said in a report shared with The Hacker News. "This malicious code is executed on any machine that pulls and runs the image, whether on user's local machines, Kubernetes clusters or cloud environments." ECR is a  container image registry service  managed by Amazon Web Services, enabling users to package code as Docker images and deploy the artifacts in a scalable manner. Public repositories hosted on ECR are displayed in what's called the  ECR Public Gallery . "By default, your account has read and write acce

Fortinet on Monday issued emergency patches for a severe security flaw affecting its FortiOS SSL-VPN product that it said is being actively exploited in the wild. Tracked as  CVE-2022-42475  (CVSS score: 9.3), the critical bug relates to a heap-based buffer overflow vulnerability that could allow an unauthenticated attacker to execute arbitrary code via specially crafted requests. The company  said  it's "aware of an instance where this vulnerability was exploited in the wild," urging customers to move quickly to apply the updates. The following products are impacted by the issue - FortiOS version 7.2.0 through 7.2.2 FortiOS version 7.0.0 through 7.0.8 FortiOS version 6.4.0 through 6.4.10 FortiOS version 6.2.0 through 6.2.11 FortiOS-6K7K version 7.0.0 through 7.0.7 FortiOS-6K7K version 6.4.0 through 6.4.9 FortiOS-6K7K version 6.2.0 through 6.2.11 FortiOS-6K7K version 6.0.0 through 6.0.14 Patches are available in FortiOS versions 7.2.3, 7.0.9, 6.4.11, and 6
