CRITICAL 9.8

DescriptionCVE.org

A Command Injection Vulnerability has been discovered in the DHCP daemon service of D-Link DIR895LA1 v102b07. The vulnerability exists in the lease renewal processing logic where the DHCP hostname parameter is directly concatenated into a system command without proper sanitization. When a DHCP client renews an existing lease with a malicious hostname, arbitrary commands can be executed with root privileges.

AnalysisAI

D-Link DIR-895L router has command injection in the DHCP daemon via the hostname parameter during lease renewal. Any device requesting a DHCP lease with a malicious hostname achieves root code execution on the router. PoC available.

Technical ContextAI

The DHCP lease renewal process concatenates the client hostname into a system command without sanitization (CWE-77). Any device on the network that sends a DHCP request with a crafted hostname can execute commands as root on the router.
