Shell command execution via unescaped bucket input
Published Jul 25, 2022 · Updated Sep 17, 2024
Command injection in google-cloudstorage-commands 0.0.1 and earlier allows remote attackers to execute shell commands via bucket input. The upload, cors, and publicRead functions interpolate the bucket argument into gsutil command strings passed directly to child_process.exec without shell escaping. Exploitation requires a consuming Node.js application to pass attacker-controlled bucket data to an exported function; command effects inherit that application's account privileges.
