CVE-2025-5492Network attack vector

Authenticated command execution via unsanitized cmd parameter

Published Jun 3, 2025 · Updated Jun 3, 2025

Command injection in D-Link DI-500WF-WT firmware 20250511 and earlier allows remote authenticated users to execute commands. The sub_456DE8 handler for /msp_info.htm?flag=cmd in /usr/sbin/jhttpd passes the cmd parameter to a command context without neutralizing command syntax. Access to the authenticated web interface is required, and successful exploitation can read, alter, or interrupt device operations.
