Summary

Arbitrary configuration injection via `git submodule deinit`

Details

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
