CVE-2022-29171Network attack vector

Remote code execution via arbitrary callsignCommand

Published May 5, 2022 · Updated Apr 23, 2025

Command injection in Sourcegraph before 3.38.0 allows remote authenticated users to execute arbitrary commands in gitserver. The Gitolite integration passes the administrator-controlled callsignCommand to gitserver for Phabricator metadata retrieval without restricting the executable command. Exploitation requires Sourcegraph site-admin rights, bundled Grafana administration, and the gitserver address, and grants access to the installation's underlying infrastructure.
