Cisco has released security fixes to address multiple security flaws, including a critical bug, that could be exploited by a threat actor to take control of an affected system or cause a denial-of service (DoS) condition. The most severe of the issues is CVE-2023-20238, which has the maximum CVSS severity rating of 10.0. It's described as an authentication bypass flaw in the Cisco BroadWorks Application Delivery Platform and Cisco BroadWorks Xtended Services Platform. Successful exploitation of the vulnerability -- a weakness in the single sign-on (SSO) implementation and discovered during internal testing -- could allow an unauthenticated, remote attacker to forge the credentials required to access an affected system. "This vulnerability is due to the method used to validate SSO tokens," Cisco  said . "An attacker could exploit this vulnerability by authenticating to the application with forged credentials. A successful exploit could allow the attacker to commit toll fraud or to e

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday warned that multiple nation-state actors are exploiting security flaws in Fortinet FortiOS SSL-VPN and Zoho ManageEngine ServiceDesk Plus to gain unauthorized access and establish persistence on compromised systems. "Nation-state advanced persistent threat (APT) actors exploited CVE-2022-47966 to gain unauthorized access to a public-facing application (Zoho ManageEngine ServiceDesk Plus), establish persistence, and move laterally through the network," according to a  joint alert  published by the agency, alongside Federal Bureau of Investigation (FBI), and Cyber National Mission Force (CNMF). The identities of the threat groups behind the attacks have not been disclosed, although the U.S. Cyber Command (USCYBERCOM)  hinted  at the involvement of Iranian nation-state crews. The findings are based on an incident response engagement conducted by CISA at an unnamed aeronautical sector organization from Februar

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  a critical security flaw in Adobe ColdFusion to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability, cataloged as  CVE-2023-26359  (CVSS score: 9.8), relates to a deserialization flaw present in Adobe ColdFusion 2018 (Update 15 and earlier) and ColdFusion 2021 (Update 5 and earlier) that could result in arbitrary code execution in the context of the current user without requiring any interaction. Deserialization  (aka unmarshaling) refers to the process of reconstructing a data structure or an object from a byte stream. But when it's performed without validating its source or sanitizing its contents, it can lead to  unexpected consequences  such as code execution or denial-of-service (DoS). It was  patched  by Adobe as part of updates issued in March 2023. As of writing, it's immediately not clear how the flaw is being  abused in the wil

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical security flaw in Citrix ShareFile storage zones controller to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active in-the-wild exploitation. Tracked as  CVE-2023-24489  (CVSS score: 9.8), the shortcoming has been described as an improper access control bug that, if successfully exploited, could allow an unauthenticated attacker to compromise vulnerable instances remotely. The problem is rooted in ShareFile's handling of cryptographic operations, enabling adversaries to upload arbitrary files, resulting in remote code execution. "This vulnerability affects all currently supported versions of customer-managed ShareFile storage zones controller before version 5.11.24," Citrix  said  in an advisory released in June. Dylan Pindur of Assetnote has been credited with discovering and reporting the issue. It's worth noting that the  first signs of exploitatio

Four security vulnerabilities in the ScrutisWeb ATM fleet monitoring software made by Iagona could be exploited to remotely break into ATMs, upload arbitrary files, and even reboot the terminals. The shortcomings were  discovered  by the Synack Red Team (SRT) following a client engagement. The issues have been addressed in ScrutisWeb version 2.1.38. "Successful exploitation of these vulnerabilities could allow an attacker to upload and execute arbitrary files," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  said  in an advisory published last month. ScrutisWeb  is a web browser-based solution for monitoring banking and retail ATM fleets, including gleaning information system status, detecting low paper alerts, shutting down or restarting a terminal, and remotely modifying data. Details of the four flaws are as follows - CVE-2023-33871  (CVSS score: 7.5) - A directory traversal vulnerability that could allow an unauthenticated user to directly access

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  a recently patched security flaw in Microsoft's .NET and Visual Studio products to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. Tracked as  CVE-2023-38180  (CVSS score: 7.5), the high-severity flaw relates to a case denial-of-service (DoS) impacting .NET and Visual Studio. It was  addressed  by Microsoft as part of its August 2023 Patch Tuesday updates shipped earlier this week, tagging it with an "Exploitation More Likely" assessment. While exact details surrounding the nature of exploitation are unclear, the Windows maker has acknowledged the existence of a proof-of-concept (PoC) in its advisory. It also said that attacks leveraging the flaw can be pulled off without any additional privileges or user interaction. "Proof-of-concept exploit code is available, or an attack demonstration is not practical for most systems," the company 

A four-year-old critical security flaw impacting Fortinet FortiOS SSL has emerged as one of the most routinely and frequently exploited vulnerabilities in 2022. "In 2022, malicious cyber actors exploited older software vulnerabilities more frequently than recently disclosed vulnerabilities and targeted unpatched, internet-facing systems," cybersecurity and intelligence agencies from the Five Eyes nations, which comprises Australia, Canada, New Zealand, the U.K., and the U.S.,  said  in a joint alert. The continued weaponization of  CVE-2018-13379 , which was also one among the most exploited bugs in  2020  and  2021 , suggests a failure on the part of organizations to apply patches in a timely manner, the authorities said. "Malicious cyber actors likely prioritize developing exploits for severe and globally prevalent CVEs," according to the advisory. "While sophisticated actors also develop tools to exploit other vulnerabilities, developing exploits for cri

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday disclosed details of a "novel persistent backdoor" called  SUBMARINE  deployed by threat actors in connection with the hack on Barracuda Email Security Gateway (ESG) appliances. "SUBMARINE comprises multiple artifacts — including a SQL trigger, shell scripts, and a loaded library for a Linux daemon — that together enable execution with root privileges, persistence, command and control, and cleanup," the agency  said . The findings come from an analysis of malware samples obtained from an unnamed organization that had been compromised by threat actors exploiting a critical flaw in ESG devices,  CVE-2023-2868  (CVSS score: 9.8), which allows for remote command injection. Evidence gathered so far shows that the attackers behind the activity, a suspected China nexus-actor tracked by Mandiant as  UNC4841 , leveraged the flaw as a zero-day in October 2022 to gain initial access to victim envir

Cybersecurity agencies in Australia and the U.S. have  published  a joint cybersecurity advisory warning against security flaws in web applications that could be exploited by malicious actors to orchestrate data breach incidents and steal confidential data. This includes a specific class of bugs called Insecure Direct Object Reference ( IDOR ), a type of access control flaw that occurs when an application utilizes user-supplied input or an identifier for direct access to an internal resource, such as a database record, without any additional validations. A  typical example  of an IDOR flaw is the ability of a user to trivially change the URL (e.g., https://example[.]site/details.php?id= 12345 ) to obtain unauthorized data of another transaction (i.e., https://example[.]site/details.php?id= 67890 ). "IDOR vulnerabilities are access control vulnerabilities enabling malicious actors to modify or delete data or access sensitive data by issuing requests to a website or a web appli

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory on Thursday warning that the newly disclosed critical security flaw in Citrix NetScaler Application Delivery Controller (ADC) and Gateway devices is being abused to drop web shells on vulnerable systems. "In June 2023, threat actors exploited this vulnerability as a zero-day to drop a web shell on a critical infrastructure organization's non-production environment NetScaler ADC appliance," the agency  said . "The web shell enabled the actors to perform discovery on the victim's active directory (AD) and collect and exfiltrate AD data. The actors attempted to move laterally to a domain controller but network segmentation controls for the appliance blocked movement." The shortcoming in question is  CVE-2023-3519  (CVSS score: 9.8), a code injection bug that could result in unauthenticated remote code execution. Citrix, earlier this week, released patches for the issue and

Microsoft on Wednesday announced that it's expanding cloud logging capabilities to help organizations investigate cybersecurity incidents and gain more visibility after facing criticism in the wake of a recent  espionage attack campaign  aimed at its email infrastructure. The tech giant said it's making the change in direct response to increasing frequency and evolution of nation-state cyber threats. It's expected to roll out starting in September 2023 to all government and commercial customers. "Over the coming months, we will include access to wider cloud security logs for our worldwide customers at no additional cost," Vasu Jakkal, corporate vice president of security, compliance, identity, and management at Microsoft,  said . "As these changes take effect, customers can use Microsoft Purview Audit to centrally visualize more types of cloud log data generated across their enterprise." As part of this change, users are expected to receive access to

U.S. cybersecurity and intelligence agencies have  released  a set of recommendations to address security concerns with 5G standalone network slicing and harden them against possible threats. "The threat landscape in 5G is dynamic; due to this, advanced monitoring, auditing, and other analytical capabilities are required to meet certain levels of network slicing service level requirements over time," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the National Security Agency (NSA)  said . 5G is the fifth-generation technology standard for broadband cellular networks, offering increased data speeds and lower latency. Network slicing is an architectural model that allows mobile service providers to partition their network up into several independent "slices" in order to create virtual networks that cater to different clients and use cases. The latest advisory builds upon guidance  previously issued  by the agencies in December 2022, warning

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has alerted of two security flaws impacting Rockwell Automation ControlLogix EtherNet/IP (ENIP) communication module models that could be exploited to achieve remote code execution and denial-of-service (DoS). "The results and impact of exploiting these vulnerabilities vary depending on the ControlLogix system configuration, but they could lead to denial or loss of control, denial or loss of view, theft of operational data, or manipulation of control for disruptive or destructive consequences on the industrial process for which the ControlLogix system is responsible," Draogos  said . The list of flaws is as follows - CVE-2023-3595  (CVSS score: 9.8) - An out-of-bounds write flaw impacting 1756 EN2* and 1756 EN3* products that could result in arbitrary code execution with persistence on the target system through maliciously crafted common industrial protocol ( CIP ) messages.

MITRE has released its annual list of the Top 25 "most dangerous software weaknesses" for the year 2023. "These weaknesses lead to serious vulnerabilities in software," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  said . "An attacker can often exploit these vulnerabilities to take control of an affected system, steal data, or prevent applications from working." The  list  is based on an  analysis  of public vulnerability data in the National Vulnerability Data ( NVD ) for root cause mappings to CWE weaknesses for the previous two years. A total of 43,996 CVE entries were examined and a score was attached to each of them based on prevalence and severity. Coming out top is Out-of-bounds Write, followed by Cross-site Scripting, SQL Injection, Use After Free, OS Command Injection, Improper Input Validation, Out-of-bounds Read, Path Traversal, Cross-Site Request Forgery (CSRF), and Unrestricted Upload of File with Dangerous Type. Out-of

The U.S. Cybersecurity and Infrastructure Security Agency has  added  a batch of six flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. This comprises three vulnerabilities that Apple patched this week ( CVE-2023-32434, CVE-2023-32435, and CVE-2023-32439 ), two flaws in VMware ( CVE-2023-20867  and  CVE-2023-20887 ), and one shortcoming impacting Zyxel devices ( CVE-2023-27992 ). CVE-2023-32434 and CVE-2023-32435, both of which allow code execution, are said to have been exploited as zero-days to deploy spyware as part of a years-long cyber espionage campaign that commenced in 2019. Dubbed Operation Triangulation, the activity culminates in the deployment of  TriangleDB  that's designed to harvest a wide range of information from compromised devices, such as creating, modifying, removing, and stealing files, listing and terminating processes, gathering credentials from iCloud Keychain, and tracking a user's location. The

Progress Software on Thursday  disclosed  a third vulnerability impacting its MOVEit Transfer application, as the Cl0p cybercrime gang deployed extortion tactics against affected companies. The  new flaw , which is being tracked as CVE-2023-35708 , also concerns an SQL injection vulnerability that "could lead to escalated privileges and potential unauthorized access to the environment." The company is urging its customers to disable all HTTP and HTTPs traffic to MOVEit Transfer on ports 80 and 443 to safeguard their environments while a fix is being prepared to address the weakness. The cloud managed file transfer solution has been fully patched. The revelation comes a week after Progress  divulged  another set of SQL injection vulnerabilities ( CVE-2023-35036 ) that it said could be weaponized to access the application's database content. The vulnerabilities join  CVE-2023-34362 , which was  exploited  as a zero-day by the Clop ransomware gang in data theft attacks

The threat actors behind the  LockBit  ransomware-as-a-service (RaaS) scheme have extorted $91 million following hundreds of attacks against numerous U.S. organizations since 2020. That's according to a  joint bulletin  published by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Multi-State Information Sharing and Analysis Center (MS-ISAC), and other partner authorities from Australia, Canada, France, Germany, New Zealand, and the U.K. "The LockBit ransomware-as-a-service (RaaS) attracts affiliates to use LockBit for conducting ransomware attacks, resulting in a large web of unconnected threat actors conducting wildly varying attacks," the agencies  said . LockBit, which first burst onto the scene in late 2019, has continued to be disruptive and prolific, targeting as many as 76 victims in May 2023 alone, per statistics shared by  Malwarebytes  last week. The Russia-linked cartel has claimed responsibil
