CVE-2024-32021
Description
A vulnerability was found in Git. This flaw allows an unauthenticated attacker to place a repository on their target's local system that contains symlinks. During the cloning process, Git could be tricked into creating hardlinked arbitrary files into their repository's objects/ directory, impacting availability and integrity.
Statement
While the Git vulnerability described involves the potential creation of hardlinks to arbitrary files during the cloning process, its severity is considered Low due to several mitigating factors. First, successful exploitation relies on the presence of specific conditions, including the use of local cloning over the filesystem and the ability to manipulate symbolic links within the source repository. Secondly, the impact is limited to the creation of hardlinks to user-readable files, which may not necessarily lead to immediate compromise or exploitation of sensitive data. Additionally, the likelihood of exploitation is reduced by the need for direct access to the filesystem where the cloning operation occurs.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
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).
