The embedded Web server in the Cisco Cable Modem with Digital Voice models DPC2203 and EPC2203 contains a buffer overflow vulnerability that can be exploited remotely without authentication. And the Web-based administration interfaces of the Cisco DPC3941 Wireless Residential Gateway with Digital Voice and Cisco DPC3939B Wireless Residential Voice Gateway are affected by a vulnerability that could lead to information disclosure. In addition, the Cisco Model DPQ3925 8x4 DOCSIS 3.0 Wireless Residential Gateway with EDVA is affected by a separate vulnerability, also triggered by malicious HTTP requests, that could lead to a denial-of-service condition.
