GitHub addresses maximum severity Enterprise Server vulnerability

GitHub has rolled out fixes to address a maximum severity flaw in the GitHub Enterprise Server (GHES) that could allow an attacker to bypass authentication protections.

Tracked as CVE-2024-4985 (CVSS score: 10.0), the issue could permit unauthorized access to an instance without requiring prior authentication.

"On instances that use SAML single sign-on (SSO) authentication with the optional encrypted assertions feature, an attacker could forge a SAML response to provision and/or gain access to a user with administrator privileges," the company said in an advisory. GHES is a self-hosted platform for software development, allowing organizations to store and build software using Git version control as well as automate the deployment pipeline.
