Summary

An unauthenticated command injection vulnerability exists in the cookie handling process of the lighttpd web server on D-Link DSP-W110A1 firmware version 1.05B01. This occurs when specially crafted cookie values are processed, allowing remote attackers to execute arbitrary commands on the underlying Linux operating system. Successful exploitation enables full system compromise.
