What is CVE-2009-20005?

A stack-based buffer overflow vulnerability is present in the UtilConfigHome.csp endpoint of InterSystems Caché version 2009.1. This vulnerability can be exploited by sending a specially crafted HTTP GET request with an oversized argument to the .csp handler. The lack of proper bounds checking allows for the overflow of a stack buffer, which can lead to the overwriting of control structures. This condition could enable an attacker to execute arbitrary code, significantly compromising the affected system. The specific version range that remains vulnerable has not been detailed, and there is no confirmed information regarding any remediation or patch for this issue.
