Cisco Spa100 Series Analog Telephone Adapters
The issue is related to improper validation of user-supplied input to the web-based management interface, which could allow an authenticated, adjacent attacker to execute arbitrary code with elevated privileges. An attacker could exploit this by authenticating to the web-based management interface and sending crafted requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code with elevated privileges. The web-based management interface is enabled by default. Additionally, there is a buffer overflow issue in the web-based management interface of the Cisco SPA100 Series IP phones' firmware, which could be exploited by a remote attacker using a specially crafted request to execute arbitrary code with elevated privileges.
