CVE-2024-2279· NVD / CVE Program· CNA GitLab

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in GitLab

Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.57% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: GitLab GitLab 16.10.2, 16.8.6, 16.9.4.
  • Severity is disputed: the assigning authority (CNA) scores it 8.7, NVD 5.4.

Low priority for now. Upgrade to GitLab GitLab 16.10.2, 16.8.6, 16.9.4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue has been discovered in GitLab CE/EE affecting all versions starting from 16.7 to 16.8.6 all versions starting from 16.9 before 16.9.4, all versions starting from 16.10 before 16.10.2. Using the autocomplete for issues references feature a crafted payload may lead to a stored XSS, allowing attackers to perform arbitrary actions on behalf of victims.

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.
