What is CVE-2025-58098?

A security vulnerability exists in Apache HTTP Server versions 2.4.65 and earlier, allowing an attacker to exploit the Server Side Includes (SSI) functionality with the mod_cgid module. This issue arises when the server mishandles the shell-escaped query strings passed to commands executed by the #exec directives. To mitigate this risk, it is critical for users to upgrade their Apache HTTP Server to version 2.4.66 or later, where this issue has been resolved.

Affected Version(s)

Apache HTTP Server 0 < 2.4.66

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
