CVE-2023-24736Public exploitNetwork attack vector

Authenticated command execution via untrusted decompress parameter

Published Mar 6, 2023 · Updated Aug 2, 2024

Command injection in PMB 7.4.6 allows remote authenticated users to execute arbitrary shell commands through a crafted decompression request. The restaure_act.php endpoint sends the attacker-controlled decompress parameter to exec when external decompression is selected and a referenced file meets the required marker format. Access to the administrative endpoint and a usable filename reference are required, after which commands run with the privileges of the PMB server process.
