CVE-2015-7545
CriticalSummary
In Git versions before 2.3.10, 2.4.x before 2.4.10, 2.5.x before 2.5.4, and 2.6.x before 2.6.1, there is a vulnerability that does not properly restrict allowed protocols in remote helper programs. This may allow remote attackers to execute arbitrary code via a URL in a .gitmodules file or other unknown sources in a submodule.
Risk Assessment
An attacker could exploit this vulnerability to execute arbitrary code remotely, posing a serious security threat to systems using the vulnerable versions of Git.
Recommendation
It is recommended to update Git to the latest version to eliminate this vulnerability and to implement additional precautions when managing .gitmodules files.
