CVE-2022-1884
A remote command execution vulnerability exists in gogs/gogs versions <=0.12.7 when deployed on a Windows server. The vulnerability arises due to improper validation of the tree_path parameter during file uploads. An attacker can set tree_path=.git. to upload a file into the .git directory, allowing them to write or rewrite the .git/config file. If the core.sshCommand is set, this can lead to remote command execution.
