Description

Multiple vulnerabilities in the web-based management interface of Cisco Small Business SPA300 Series IP Phones and Cisco Small Business SPA500 Series IP Phones could allow an unauthenticated, remote attacker to execute arbitrary commands on the underlying operating system with root privileges. These vulnerabilities exist because incoming HTTP packets are not properly checked for errors, which could result in a buffer overflow. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to overflow an internal buffer and execute arbitrary commands at the root privilege level.

Affected configurations

• cisco spa 301 firmware • cisco spa 303 firmware • cisco spa 501g firmware • cisco spa 502g firmware • cisco spa 504g firmware • cisco spa 508g firmware • cisco spa 509g firmware • cisco spa 512g firmware • cisco spa 514g firmware • cisco spa 525g firmware • cisco spa 525g2 firmware
