Medium

Base vector

AV:N/AC:M/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions: git versions 2.15.1 and earlier

Description: The issue is related to an Input Validation Error in the Client component, which can lead to problems including messing up terminal configuration and potentially allowing Remote Code Execution (RCE). This can be exploited when a user interacts with a malicious git server or if their traffic is modified in a Man-In-The-Middle (MITM) attack.

Recommendations: For git versions 2.15.1 and earlier, update to a version later than 2.15.1 to resolve the issue. As a temporary workaround, consider restricting interactions with untrusted git servers and securing network traffic to minimize the risk of exploitation.
