OS command injection

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

A remote attacker can send specially crafted HTTP request with query string, contain a %3D sequence but no = (equals sign) character, inject and execute arbitrary OS commands on vulnerable system with privileges of the web server.

Successful exploitation of the vulnerability results in denial of service or arbitrary code execution on the vulnerable system.
