Background
Gogs is an open-source self-hosted Git service written in Go. It provides a lightweight and easy-to-use platform for managing repositories, users, and organizations. Gogs allows users to collaborate on code, track changes, and manage their projects effectively. However, a vulnerability has been discovered in Gogs that allows for OS command injection.
Vulnerability Detail
The OS command injection vulnerability in Gogs allows an attacker to execute arbitrary commands on the underlying operating system. This can be exploited by an authenticated user with write access to a repository's file editor. By crafting a malicious file name or content, an attacker can inject arbitrary commands that will be executed when the file is accessed or modified. This can lead to unauthorized access, data leakage, and potential compromise of the host system.
