CVE-2025-60697

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the prog.cgi and rc binaries. The sub_4438A4 function in prog.cgi stores user-supplied DDNS parameters (ServerAddress and Hostname) in NVRAM via nvram_safe_set. These values are later retrieved in the start_DDNS_ipv4 function of rc using nvram_safe_get and concatenated into DDNS shell commands executed via twsystem() without proper sanitization. Partial string comparison is performed but is insufficient to prevent command injection. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.
