Code Injection Vulnerability in GitHub Enterprise Server Allows Arbitrary Code Execution via Message Handling
Noroxi assessment
Priority: Monitor (action score 28/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.38% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- Fixed version: GitHub Enterprise Server 3.11.17, 3.12.11, 3.13.6.
Low priority for now. Upgrade to GitHub Enterprise Server 3.11.17, 3.12.11, 3.13.6 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
A Code Injection vulnerability was identified in GitHub Enterprise Server that allowed attackers to inject malicious code into the query selector via the identity property in the message handling function. This enabled the exfiltration of sensitive data by manipulating the DOM, including authentication tokens. To execute the attack, the victim must be logged into GitHub and interact with the attacker controlled malicious webpage containing the hidden iframe. This vulnerability occurs due to an improper sequence of validation, where the origin check occurs after accepting the user-controlled identity property. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.11.16, 3.12.10, 3.13.5, 3.14.2, and 3.15.0. This vulnerability was reported via the GitHub Bug Bounty program.
