Technical details

A format string vulnerability (CWE-134) exists in the '/web/cgi-bin/greece/rhea' CGI binary of the D-Link DCS-935L IP camera. The issue stems from the 'snprintf' function improperly handling the 'sn' and 'hwv' HTTP parameters by passing user-supplied input directly as a format string argument. A remote, authenticated attacker can exploit this by sending specially crafted GET requests to leak stack memory or write arbitrary values to memory using format specifiers like '%n'. Successful exploitation can lead to arbitrary code execution with root privileges. While authentication is typically required, requests originating from localhost (127.0.0.1) may bypass these checks.
