Detailsinfo

A vulnerability, which was classified as problematic, was found in GitHub Enterprise Server up to 3.11.15/3.12.9/3.13.4/3.14.1. This affects an unknown code block of the component SAML SSO. The manipulation with an unknown input leads to a signature verification vulnerability. CWE is classifying the issue as CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An improper verification of cryptographic signature vulnerability was identified in GitHub Enterprise Server that allowed SAML SSO authentication to be bypassed resulting in unauthorized provisioning of users and access to the instance. Exploitation required the encrypted assertions feature to be enabled, and the attacker would require direct network access as well as a signed SAML response or metadata document. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.15 and was fixed in versions 3.11.16, 3.12.10, 3.13.5, and 3.14.2. This vulnerability was reported via the GitHub Bug Bounty program.

It is possible to read the advisory at docs.github.com. This vulnerability is uniquely identified as CVE-2024-9487 since 10/03/2024. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

Upgrading to version 3.11.16, 3.12.10, 3.13.5, 3.14.2 or 3.15 eliminates this vulnerability. The upgrade is hosted for download at docs.github.com.
