Signature Detail

HTTP: FastCGI Memory Corruption

This signature detects attempts to exploit a known vulnerability in the Microsoft IIS FastCGI Module. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server. Due to the nature of the issue, this signature can be false positive prone; only apply if using FastCGI. The recommended action is not set by default, due to the risk of false positives. If FastCGI is present and un-patched, the action should be drop.
