CVE-2024-52006: Newline confusion in credential helpers can lead to credential exfiltration in git

Noroxi assessment

Priority: Monitor (action score 8/100)

  • 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: 1% (FIRST EPSS); higher than 63.8% of all records.
  • 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: azl3 git 2.45.2-1 on Azure Linux 3.0 2.45.3-1; azl3 git 2.45.3-1 on Azure Linux 3.0 2.45.3-1; cbl2 git 2.39.4-1 on CBL Mariner 2.0 2.40.4-1.

Low priority for now. Upgrade to azl3 git 2.45.2-1 on Azure Linux 3.0 2.45.3-1; azl3 git 2.45.3-1 on Azure Linux 3.0 2.45.3-1; cbl2 git 2.39.4-1 on CBL Mariner 2.0 2.40.4-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. Git defines a line-based protocol that is used to exchange information between Git and Git credential helpers. Some ecosystems (most notably, .NET and node.js) interpret single Carriage Return characters as newlines, which renders the protections against CVE-2020-5260 incomplete for credential helpers that treat Carriage Returns in this way. This issue has been addressed in commit `b01b9b8` which is included in release versions v2.48.1, v2.47.2, v2.46.3, v2.45.3, v2.44.3, v2.43.6, v2.42.4, v2.41.3, and v2.40.4. Users are advised to upgrade. Users unable to upgrade should avoid cloning from untrusted URLs, especially recursive clones.
