Code execution via SSH username option injection
Published Apr 26, 2024 · Updated Aug 2, 2024
Argument injection in gix-transport before 0.42.0 allows remote authenticated users to execute arbitrary commands through a clone URL. Its SSH transport passes a hyphen-prefixed username@host value as an argument to external ssh, which interprets the value as options such as -F. Execution requires an application to process the malicious URL from a working directory containing an attacker-controlled SSH configuration file.
