Atlassian has released software fixes to address  four critical flaws  in its software that, if successfully exploited, could result in remote code execution. The list of vulnerabilities is below - CVE-2022-1471  (CVSS score: 9.8) - Deserialization vulnerability in  SnakeYAML library  that can lead to remote code execution in multiple products CVE-2023-22522  (CVSS score: 9.0) - Remote code execution vulnerability in Confluence Data Center and Confluence Server (affects all versions including and after 4.0.0) CVE-2023-22523  (CVSS score: 9.8) - Remote code execution vulnerability in Assets Discovery for Jira Service Management Cloud, Server, and Data Center (affects all versions up to but not including 3.2.0-cloud / 6.2.0 data center and server) CVE-2023-22524  (CVSS score: 9.6) - Remote code execution vulnerability in Atlassian Companion app for macOS (affects all versions up to but not including 2.0.0) Atlassian described CVE-2023-22522 as a template injection flaw that allo

New research has found that over 15,000 Go module repositories on GitHub are vulnerable to an attack called repojacking. "More than 9,000 repositories are vulnerable to repojacking due to GitHub username changes," Jacob Baines, chief technology officer at VulnCheck,  said  in a report shared with The Hacker News. "More than 6,000 repositories were vulnerable to repojacking due to account deletion." Collectively, these repositories account for no less than 800,000 Go module-versions. Repojacking , a portmanteau of "repository" and "hijacking," is an attack technique that allows a bad actor to take advantage of account username changes and deletions to create a repository with the same name and the pre-existing username to stage open-source software supply chain attacks. Earlier this June, cloud security firm Aqua  revealed  that millions of software repositories on GitHub are likely vulnerable to the threat, urging organizations that undergo

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

Apple has  released  software updates for iOS, iPadOS, macOS, and Safari web browser to address two security flaws that it said have come under active exploitation in the wild on older versions of its software. The vulnerabilities, both of which reside in the WebKit web browser engine, are described below - CVE-2023-42916  - An out-of-bounds read issue that could be exploited to leak sensitive information when processing web content. CVE-2023-42917  - A memory corruption bug that could result in arbitrary code execution when processing web content. Apple said it's aware of reports exploiting the shortcomings "against versions of iOS before iOS 16.7.1," which was released on October 10, 2023. Clément Lecigne of Google's Threat Analysis Group (TAG) has been credited with discovering and reporting the twin flaws. The iPhone maker did not provide additional information regarding ongoing exploitation, but previously disclosed zero-days in iOS have been used to  de

The maintainers of the open-source file-sharing software ownCloud have warned of three critical security flaws that could be exploited to disclose sensitive information and modify files. A brief description of the vulnerabilities is as follows - CVE-2023-49103 (CVSS score: 10.0) - Disclosure of sensitive credentials and configuration in containerized deployments impacting graphapi versions from 0.2.0 to 0.3.0. CVE-2023-49105 (CVSS score: 9.8) - WebDAV Api Authentication Bypass using Pre-Signed URLs impacting core versions from 10.6.0 to 10.13.0. CVE-2023-49104 (CVSS score: 9.0) - Subdomain Validation Bypass impacting oauth2 prior to version 0.6.1. "The 'graphapi' app relies on a third-party library that provides a URL. When this URL is accessed, it reveals the configuration details of the PHP environment (phpinfo)," the company  said  of the first flaw. "This information includes all the environment variables of the web server. In containerized deplo

A new set of 48 malicious npm packages have been discovered in the npm repository with capabilities to deploy a reverse shell on compromised systems. "These packages, deceptively named to appear legitimate, contained obfuscated JavaScript designed to initiate a reverse shell on package install," software supply chain security firm Phylum  said . All the counterfeit packages have been published by an npm user named  hktalent  ( GitHub ,  X ). As of writing, 39 of the packages uploaded by the author are still available for download. The attack chain is triggered post the installation of the package via an install hook in the package.json that calls a JavaScript code to establish a  reverse shell  to rsh.51pwn[.]com. "In this particular case, the attacker published dozens of benign-sounding packages with several layers of obfuscation and deceptive tactics in an attempt to ultimately deploy a reverse shell on any machine that simply installs one of these packages,"

Atlassian has warned of a critical security flaw in Confluence Data Center and Server that could result in "significant data loss if exploited by an unauthenticated attacker." Tracked as  CVE-2023-22518 , the vulnerability is rated 9.1 out of a maximum of 10 on the CVSS scoring system. It has been described as an instance of "improper authorization vulnerability." All versions of Confluence Data Center and Server are susceptible to the bug, and it has been addressed in the following versions - 7.19.16 or later 8.3.4 or later 8.4.4 or later 8.5.3 or later, and 8.6.1 or later That said, the Australian company emphasized that "there is no impact to confidentiality as an attacker cannot exfiltrate any instance data." No other details about the flaw and the exact method by which an adversary can take advantage of it have been made available, likely owing to the fact that doing so could enable threat actors to devise an exploit. Atlassian is also u

Image Source: JFrog Security Research Patches have been released for  two security flaws  impacting the Curl data transfer library, the most severe of which could potentially result in code execution. The list of vulnerabilities is as follows - CVE-2023-38545  (CVSS score: 7.5) - SOCKS5 heap-based buffer overflow vulnerability CVE-2023-38546  (CVSS score: 5.0) - Cookie injection with none file CVE-2023-38545 is the more severe of the two, and has been  described  by the project's lead developer, Daniel Stenberg, as "probably the worst Curl security flaw in a long time." It affects libcurl versions 7.69.0 to and including 8.3.0. "This flaw makes Curl overflow a heap-based buffer in the  SOCKS5  proxy handshake," the maintainers said in an advisory. "When Curl is asked to pass along the hostname to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by Curl itself, the maximum length that hostname can be is 255 bytes.&quo

The maintainers of the  Curl library  have released an advisory warning of two security vulnerabilities that are expected to be addressed as part of an forthcoming update set for release on October 11, 2023. This  includes  a high-severity and a low-severity flaw tracked under the identifiers CVE-2023-38545 and CVE-2023-38546, respectively. Additional details about the issues and the exact version ranges impacted have been withheld owing to the possibility that the information could be used to "help identify the problem (area) with a very high accuracy." That said, the "last several years" of versions of the library are said to be affected.  "Sure, there is a minuscule risk that someone can find this (again) before we ship the patch, but this issue has stayed undetected for years for a reason," Daniel Stenberg, the lead developer behind the project, said in a message posted on GitHub. Curl, powered by libcurl, is a  popular command-line tool  for tra

A high-severity security flaw has been disclosed in N-Able's Take Control Agent that could be exploited by a local unprivileged attacker to gain SYSTEM privileges. Tracked as  CVE-2023-27470  (CVSS score: 8.8), the  issue  relates to a Time-of-Check to Time-of-Use ( TOCTOU ) race condition vulnerability, which, when successfully exploited, could be leveraged to delete arbitrary files on a Windows system. The security shortcoming, which impacts versions 7.0.41.1141 and prior, has been addressed in version 7.0.43 released on March 15, 2023, following responsible disclosure by Mandiant on February 27, 2023. Time-of-Check to Time-of-Use falls under a category of software flaws wherein a program checks the state of a resource for a specific value, but that value changes before it's actually used, effectively invalidating the results of the check. An exploitation of such a flaw can result in a loss of integrity and trick the program into performing actions that it shouldn't

A new vulnerability disclosed in GitHub could have exposed thousands of repositories at risk of repojacking attacks, new findings show. The flaw "could allow an attacker to exploit a race condition within GitHub's repository creation and username renaming operations," Checkmarx security researcher Elad Rapoport  said  in a technical report shared with The Hacker News. "Successful exploitation of this vulnerability impacts the open-source community by enabling the hijacking of over 4,000 code packages in languages such as Go, PHP, and Swift, as well as GitHub actions." Following responsible disclosure on March 1, 2023, the Microsoft-owned code hosting platform has addressed the issue as of September 1, 2023. Repojacking , short for  repository hijacking , is a technique where a threat actor is able to bypass a security mechanism called popular repository namespace retirement and ultimately control of a repository. What the protection measure does is preven

Software services provider Ivanti is  warning  of a new critical zero-day flaw impacting Ivanti Sentry (formerly MobileIron Sentry) that it said is being actively exploited in the wild, marking an escalation of its security woes. Tracked as  CVE-2023-38035  (CVSS score: 9.8), the issue has been described as a case of authentication bypass impacting versions 9.18 and prior due to what it called an due to an insufficiently restrictive Apache HTTPD configuration. "If exploited, this vulnerability enables an unauthenticated actor to access some sensitive APIs that are used to configure the Ivanti Sentry on the administrator portal (port 8443, commonly MICS)," the company  said . "While the issue has a high CVSS score, there is a low risk of exploitation for customers who do not expose port 8443 to the internet." Successful exploitation of the bug could allow an attacker to change configuration, run system commands, or write files onto the system. It's recommen

A high-severity security flaw has been disclosed in the Python URL parsing function that could be exploited to bypass domain or protocol filtering methods implemented with a blocklist, ultimately resulting in arbitrary file reads and command execution. "urlparse has a parsing problem when the entire URL starts with blank characters," the CERT Coordination Center (CERT/CC) said in a Friday advisory. "This problem affects both the parsing of hostname and scheme, and eventually causes any blocklisting methods to fail." The flaw has been assigned the identifier  CVE-2023-24329  and carries a CVSS score of 7.5. Security researcher Yebo Cao has been credited with discovering and reporting the issue in August 2022. It has been addressed in the following versions - >= 3.12 3.11.x >= 3.11.4 3.10.x >= 3.10.12 3.9.x >= 3.9.17 3.8.x >= 3.8.17, and  3.7.x >= 3.7.17 urllib.parse  is a widely used parsing function that makes it possible to break dow

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

Users of Metabase, a popular business intelligence and data visualization software package, are being advised to update to the latest version following the discovery of an "extremely severe" flaw that could result in pre-authenticated remote code execution on affected installations. Tracked as CVE-2023-38646 , the issue impacts open-source editions prior to 0.46.6.1 and Metabase Enterprise versions before 1.46.6.1. "An unauthenticated attacker can run arbitrary commands with the same privileges as the Metabase server on the server you are running Metabase on," Metabase said in an advisory released last week. The issue has also been addressed in the following older versions - 0.45.4.1 and 1.45.4.1 0.44.7.1 and 1.44.7.1, and 0.43.7.2 and 1.43.7.2 While there is no evidence that the issue has been exploited in the wild, data gathered by the Shadowserver Foundation shows that 5,488 out of the total 6,936 Metabase instances are vulnerable as of July 26, 202

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

Adobe has released a fresh round of updates to address an incomplete fix for a recently disclosed ColdFusion flaw that has come under active exploitation in the wild. The critical shortcoming, tracked as  CVE-2023-38205  (CVSS score: 7.5), has been described as an instance of improper access control that could result in a security bypass. It impacts the following versions: ColdFusion 2023 (Update 2 and earlier versions) ColdFusion 2021 (Update 8 and earlier versions), and ColdFusion 2018 (Update 18 and earlier versions) "Adobe is aware that CVE-2023-38205 has been exploited in the wild in limited attacks targeting Adobe ColdFusion," the company  said . The update also addresses two other flaws, including a critical deserialization bug ( CVE-2023-38204 , CVSS score: 9.8) that could lead to remote code execution and a second improper access control flaw that could also pave the way for a security bypass ( CVE-2023-38206 , CVSS score: 5.3). The disclosure arrives days

A Microsoft Windows policy loophole has been observed being exploited primarily by native Chinese-speaking threat actors to forge signatures on kernel-mode drivers. "Actors are leveraging multiple open-source tools that alter the signing date of kernel mode drivers to load malicious and unverified drivers signed with expired certificates," Cisco Talos said in an  exhaustive two-part report  shared with The Hacker News. "This is a major threat, as access to the kernel provides complete access to a system, and therefore total compromise." Following responsible disclosure, Microsoft  said  it has taken steps to block all certificates to mitigate the threat. It further stated that its investigation found "the activity was limited to the abuse of several developer program accounts and that no Microsoft account compromise has been identified." The tech giant, besides suspending developer program accounts involved in the incident, emphasized that the threat a

A few weeks ago, the 32nd edition of RSA, one of the world's largest cybersecurity conferences, wrapped up in San Francisco. Among the highlights, Kevin Mandia, CEO of Mandiant at Google Cloud, presented a retrospective on  the state of cybersecurity . During his keynote, Mandia stated: "There are clear steps organizations can take beyond common safeguards and security tools to strengthen their defenses and increase their chances of detecting, thwarting or minimizing attack [...] Honeypots , or fake accounts deliberately left untouched by authorized users,  are effective at helping organizations detect intrusions or malicious activities that security products can't stop ". "Build honeypots" was one of his seven pieces of advice to help organizations avoid some of the attacks that might require engagement with Mandiant or other incident response firms. As a reminder, honeypots are  decoy systems  that are set up to lure attackers and divert their attentio

The threat actors behind the ransomware attack on Taiwanese PC maker MSI last month have leaked the company's private code signing keys on their dark website. "Confirmed, Intel OEM private key leaked, causing an impact on the entire ecosystem," Alex Matrosov, founder and CEO of firmware security firm Binarly,  said  in a tweet over the weekend. "It appears that Intel Boot Guard may not be effective on certain devices based on the 11th Tiger Lake, 12th Adler Lake, and 13th Raptor Lake." Present in the leaked data are firmware image signing keys associated with 57 PCs and private signing keys for Intel Boot Guard used on 116 MSI products. The Boot Guard keys from MSI are believed to impact several device vendors, including Intel, Lenovo and Supermicro. Intel Boot Guard is a  hardware-based security technology  that's designed to protect computers against executing tampered UEFI firmware. The development comes a month after MSI  fell victim  to a double

PHP software package repository Packagist revealed that an "attacker" gained access to four inactive accounts on the platform to hijack over a dozen packages with over 500 million installs to date. "The attacker forked each of the packages and replaced the package description in  composer.json  with their own message but did not otherwise make any malicious changes," Packagist's Nils Adermann  said . "The package URLs were then changed to point to the forked repositories." The four user accounts are said to have had access to a total of 14 packages, including multiple Doctrine packages. The incident took place on May 1, 2023. The complete list of impacted packages is as follows - acmephp/acmephp acmephp/core acmephp/ssl doctrine/doctrine-cache-bundle doctrine/doctrine-module doctrine/doctrine-mongo-odm-module doctrine/doctrine-orm-module doctrine/instantiator growthbook/growthbook jdorn/file-system-cache jdorn/sql-formatter khanamiryan/
