CVE-2022-39224Public exploit

Shell command execution via unvalidated payload compressor

Published Sep 21, 2022 · Updated Apr 22, 2025

OS command injection in arr-pm before 0.0.12 allows attackers to execute shell commands through a malicious RPM payload-compressor field. RPM::File#files passed that field into a shell pipeline invoking the compressor and cpio, while RPM::File#extract selected and invoked a compressor without restricting the tag to known values. Exploitation requires an application or user to process an attacker-controlled RPM with either method, and injected commands run with the privileges of that process.
