Unauthenticated RCE in AVideo notify.ffmpeg.json.php via predictable installation salt
CVE-2025-34433 is a critical unauthenticated remote code execution vulnerability in AVideo affecting versions 14.3.1 prior to 20.1. The issue is caused by predictable generation of the installation salt using PHP uniqid(). Part of the salt can be inferred from the installation timestamp exposed through the public /objects/categories.json.php endpoint, while a derived hash identifier is exposed through unauthenticated API responses. An attacker can use these disclosures to brute-force the remaining salt entropy offline. Once the salt is recovered, the attacker can encrypt a malicious payload and submit it to notify.ffmpeg.json.php, where attacker-controlled input is evaluated via eval($callback), resulting in arbitrary code execution as the web server user.
