CVE-2024-39930 is a critical-severity vulnerability rated 9.9/10 on the CVSS scale. The built-in SSH server of Gogs through 0.13.0 allows argument injection in internal/ssh/ssh.go, leading to remote code execution. Authenticated attackers can exploit this by opening an SSH connection and sending a malicious --split-string env request if the built-in SSH server is activated. EPSS estimates a 7.26% chance of exploitation in the next 30 days.

Description

The built-in SSH server of Gogs through 0.13.0 allows argument injection in internal/ssh/ssh.go, leading to remote code execution. Authenticated attackers can exploit this by opening an SSH connection and sending a malicious --split-string env request if the built-in SSH server is activated. Windows installations are unaffected.
