Descriptions

An authentication bypass vulnerability was present in the GitHub Enterprise Server (GHES) when utilizing SAML single sign-on authentication with the optional encrypted assertions feature. This vulnerability allowed an attacker to forge a SAML response to provision and/or gain access to a user with site administrator privileges. Exploitation of this vulnerability would allow unauthorized access to the instance without requiring prior authentication. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.13.0 and was fixed in versions 3.9.15, 3.10.12, 3.11.10 and 3.12.4. This vulnerability was reported via the GitHub Bug Bounty program.

Había una vulnerabilidad de omisión de autenticación en GitHub Enterprise Server (GHES) cuando se utilizaba la autenticación de inicio de sesión único SAML con la función de aserciones cifradas opcional. Esta vulnerabilidad permitió a un atacante falsificar una respuesta SAML para aprovisionar y/o obtener acceso a un usuario con privilegios de administrador del sitio. La explotación de esta vulnerabilidad permitiría el acceso no autorizado a la instancia sin requerir autenticación previa. Esta vulnerabilidad afectó a todas las versiones de GitHub Enterprise Server anteriores a la 3.13.0 y se solucionó en las versiones 3.9.15, 3.10.12, 3.11.10 y 3.12.4. Esta vulnerabilidad se informó a través del programa GitHub Bug Bounty.
