Unauthenticated code execution via serialized Guzzle object
Published Oct 19, 2022 · Updated Sep 15, 2025
Insecure deserialization in OpenCATS 0.9.6 allows remote attackers to execute code through the getDataGridPager AJAX endpoint. The endpoint deserializes the attacker-controlled p parameter, allowing a crafted Guzzle object chain to write a PHP payload into the web root. No authentication or user interaction is required; successful exploitation executes PHP with web-server privileges and can compromise application data.
