CVE-2022-25865Network attack vector

Command execution via Git fetch argument injection

Published May 13, 2022 · Updated Sep 16, 2024

Command injection in Microsoft workspace-tools before 0.18.4 allows remote attackers to execute arbitrary commands through crafted Git fetch arguments. The fetchRemoteBranch function passes its remote and remoteBranch parameters after the git fetch subcommand without an end-of-options marker, so values beginning with Git flags are parsed as options. Exploitation requires a consuming application to pass attacker-controlled values into this library API; injected --upload-pack values execute commands with that application's privileges.
