CVE-2024-6800:
GitHub Enterprise Server vulnerability analysis and mitigation
Overview
CVE-2024-6800 is an XML signature wrapping vulnerability discovered in GitHub Enterprise Server (GHES) when using SAML authentication with specific identity providers utilizing publicly exposed signed federation metadata XML. The vulnerability was reported through GitHub's Bug Bounty program and affects all versions of GitHub Enterprise Server prior to 3.14, excluding versions 3.13.3, 3.12.8, 3.11.14, and 3.10.16 (NVD).
Technical details
The vulnerability is classified as a critical security flaw (CVSS v3.1 Base Score: 9.8) that involves improper verification of cryptographic signatures (CWE-347). The vulnerability allows an attacker with direct network access to GitHub Enterprise Server to forge SAML responses, enabling unauthorized access without requiring prior authentication (NVD, Cyble).
Impact
Successful exploitation of this vulnerability allows an attacker to forge SAML responses to provision and/or gain access to a user account with site administrator privileges. This could lead to complete unauthorized access to the instance, potentially compromising sensitive source code, configurations, and other critical data (NVD).
Mitigation and workarounds
GitHub has released security updates to address CVE-2024-6800. Organizations using affected versions of GitHub Enterprise Server should immediately upgrade to the fixed versions: 3.13.3, 3.12.8, 3.11.14, or 3.10.16. These updates include critical patches that resolve the XML signature wrapping vulnerability (GitHub Release Notes).
Community reactions
The cybersecurity community has recognized this as a critical vulnerability requiring immediate attention. Security researchers and organizations like Cyble have emphasized the severity of the vulnerability and its potential impact on enterprise security (Cyble).
