Description
A vulnerability in the web-based management interface of Cisco SPA112 2-Port Phone Adapters could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to a missing authentication process within the firmware upgrade function. An attacker could exploit this vulnerability by upgrading an affected device to a crafted version of firmware. A successful exploit could allow the attacker to execute arbitrary code on the affected device with full privileges. Cisco has not released firmware updates to address this vulnerability.
