CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2020-10519 – Unsafe configuration options in GitHub Pages leading to remote code execution on GitHub Enterprise Server
https://notcve.org/view.php?id=CVE-2020-10519
A remote code execution vulnerability was identified in GitHub Enterprise Server that could be exploited when building a GitHub Pages site. User-controlled configuration of the underlying parsers used by GitHub Pages were not sufficiently restricted and made it possible to execute commands on the GitHub Enterprise Server instance. To exploit this vulnerability, an attacker would need permission to create and build a GitHub Pages site on the GitHub Enterprise Server instance. This vulnerability affected all versions of GitHub Enterprise Server prior to 2.22.7 and was fixed in 2.22.7, 2.21.15, and 2.20.24. The underlying issues contributing to this vulnerability were identified through the GitHub Security Bug Bounty program. • https://docs.github.com/en/enterprise-server%402.20/admin/release-notes#2.20.24 https://docs.github.com/en/enterprise-server%402.21/admin/release-notes#2.21.15 https://docs.github.com/en/enterprise-server%402.22/admin/release-notes#2.22.7 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •

https://notcve.org/view.php?id=CVE-2017-18365
The Management Console in GitHub Enterprise 2.8.x before 2.8.7 has a deserialization issue that allows unauthenticated remote attackers to execute arbitrary code. This occurs because the enterprise session secret is always the same, and can be found in the product's source code. By sending a crafted cookie signed with this secret, one can call Marshal.load with arbitrary data, which is a problem because the Marshal data format allows Ruby objects. La consola de gestión en GitHub Enterprise, en las versiones 2.8.x anteriores a la 2.8.7, tiene un fallo de deserialización que permite a los atacantes remotos sin autenticar ejecutar código arbitrario. Esto ocurre debido a que el secreto de sesión "enterprise" es siempre el mismo y puede encontrarse en el código fuente del producto. • https://enterprise.github.com/releases/2.8.7/notes https://www.exablue.de/blog/2017-03-15-github-enterprise-remote-code-execution.html • CWE-502: Deserialization of Untrusted Data •
