CVE-2024-35242: Composer vulnerable to command injection via malicious git/hg branch names

Noroxi assessment

Priority: Monitor (action score 36/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.2% (FIRST EPSS); higher than 88.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: composer (Alpine:v3.19) 2.7.7-r0; composer (Debian:10) 1.8.4-1+deb10u4; composer (Debian:11) 2.0.9-2+deb11u3.

Low priority for now. Upgrade to composer (Alpine:v3.19) 2.7.7-r0; composer (Debian:10) 1.8.4-1+deb10u4; composer (Debian:11) 2.0.9-2+deb11u3 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

Composer is a dependency manager for PHP. On the 2.x branch prior to versions 2.2.24 and 2.7.7, the `composer install` command running inside a git/hg repository which has specially crafted branch names can lead to command injection. This requires cloning untrusted repositories. Patches are available in version 2.2.24 for 2.2 LTS or 2.7.7 for mainline. As a workaround, avoid cloning potentially compromised repositories.
