CVE-2021-34074Network attack vector

Remote command execution via arbitrary file upload

Published Jun 25, 2021 · Updated Aug 4, 2024

Arbitrary file upload in PandoraFMS 7.54 and earlier allows remote attackers to execute commands through the File Manager. The File Manager accepts crafted requests using a relative path to bypass its built-in upload protection, allowing an attacker-controlled file to be placed where server-side execution is possible. The network-reachable flaw is rated critical and permits unauthenticated remote command execution, with resulting control bounded by the web service account.
