GitHub Enterprise Server has recently addressed three security vulnerabilities, including a critical XML signature wrapping issue (CVE-2024-6800) that could result in admin privilege escalation.
Description
GitHub Enterprise Server has released fixes for three security vulnerabilities. The critical XML signature wrapping issue (CVE-2024-6800) has a CVSS score of 9.5 and could lead to admin privilege escalation. This vulnerability, reported through the GitHub Bug Bounty program [3] [6], allows threat actors to gain site administrator privileges by forging SAML responses during authentication with specific ID providers. Additionally, two medium-severity vulnerabilities (CVE-2024-7711 and CVE-2024-6337) have been addressed in versions 3.13.3, 3.12.8, 3.11.14, and 3.10.16 [1] [2] [3] [4] [5]. These vulnerabilities could potentially allow unauthorized access to private repository contents and modification of public repository issues. It is recommended that administrators update their systems promptly to prevent exploitation by malicious actors. Over 36,500 internet-connected instances [4], primarily in the US, are at risk [4].
Conclusion
Administrators should promptly update their systems to mitigate the risk of exploitation by threat actors. The recent fixes for the security vulnerabilities in GitHub Enterprise Server are crucial in safeguarding private repository contents and preventing unauthorized access. Future implications include the importance of staying vigilant and proactive in addressing security vulnerabilities to protect sensitive data and prevent potential breaches.
