Arbitrary Code Execution in D-Link Routers via Lighttpd Service

CVE-2022-41140

Summary

This vulnerability in multiple D-Link routers allows attackers situated on the same network to execute arbitrary code without requiring authentication. The flaw is rooted in the lighttpd service, which operates on TCP port 80, where improper validation of incoming data length facilitates the copying of data into a fixed-length buffer. This insufficient validation enables attackers to manipulate the system, potentially executing code with root privileges. Immediate action is recommended to secure affected routers against this exploit.
