CVE-2022-24975
Description
A flaw known as "GitBleed" was found in Git, where repositories cloned via the "–mirror" option may leak secrets or sensitive information if not properly removed/deleted earlier. This flaw allows attackers and bug bounty hunters to use this discrepancy in Git behavior to find hidden secrets and other sensitive data in public repositories.
Statement
The "GitBleed" issue can't be fixed, because it requires basic user education and can be fixed only by administrators responsible for individual repositories by analyzing a whole copy of their own repositories using the “–mirror” option and removing sensitive data using tools like BFG or git-filter-repo.
Mitigation
Organizations can mitigate this by analyzing a fuller copy of their repositories using the “–mirror” option and removing sensitive data using tools like BFG or git-filter-repo. Garbage collection and pruning in git is also recommended.
Organizations should not analyze regular cloned copies (without the “–mirror” option) since that may provide a false sense of security, and should not rely on methods of removing secrets such as deleting a branch or rewinding history via the “git reset” command.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
