CVE-2023-29007: Arbitrary configuration injection via `git submodule deinit`
Noroxi assessment
Priority: Monitor (action score 33/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 5.6% (FIRST EPSS); higher than 92.8% of all records.
- Someone with local access to the system 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: git (AlmaLinux:8) 2.39.3-1.el8_8; git-all (AlmaLinux:8) 2.39.3-1.el8_8; git-core (AlmaLinux:8) 2.39.3-1.el8_8.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to git (AlmaLinux:8) 2.39.3-1.el8_8; git-all (AlmaLinux:8) 2.39.3-1.el8_8; git-core (AlmaLinux:8) 2.39.3-1.el8_8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Git is a revision control system. Prior to versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1, a specially crafted `.gitmodules` file with submodule URLs that are longer than 1024 characters can used to exploit a bug in `config.c::git_config_copy_or_rename_section_in_file()`. This bug can be used to inject arbitrary configuration into a user's `$GIT_DIR/config` when attempting to remove the configuration section associated with that submodule. When the attacker injects configuration values which specify executables to run (such as `core.pager`, `core.editor`, `core.sshCommand`, etc.) this can lead to a remote code execution. A fix A fix is available in versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1. As a workaround, avoid running `git submodule deinit` on untrusted repositories or without prior inspection of any submodule sections in `$GIT_DIR/config`.
