Overview
CVE-2009-20005 is a known-severity vulnerability. It was published on September 16, 2025.
Technical description
A stack-based buffer overflow exists in the UtilConfigHome.csp endpoint of InterSystems Caché 2009.1. The vulnerability is triggered by sending a specially crafted HTTP GET request containing an oversized argument to the .csp handler. Due to insufficient bounds checking, the input overflows a stack buffer, allowing an attacker to overwrite control structures and execute arbitrary code. It is unknown if this vulnerability was patched and an affected version range remains undefined.

How can CyberStrike help with CVE-2009-20005?
CyberStrike is an open-source, AI-augmented pentesting engine.
