Cisco Unified IP Phone telnet server buffer overflow
|cisco-unifiedipphone-telnet-bo (40493)||High Risk|
Cisco Unified IP Phones running SIP firmware are vulnerable to a buffer overflow, caused by improper bounds checking when the telnet server is enabled and the password parameter is configured. By sending a specially-crafted command to the telnet server, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the phone with elevated privileges.
