|Cisco Small Business SPA514G IP Phones SIP Denial of Service Vulnerability
The Session Initiation Protocol (SIP) implementation in the Cisco Small Business SPA514G IP Phones contains an issue that could cause the device to require a manual restart if exploited by a remote attacker. SPA514G, SPA514G-RC, and SPA514G-XU IP Phones are potentially affected.
An attacker could take advantage of this issue and send malformed SIP messages to an affected device. Malformed SIP messages could cause the device to become unresponsive until restarted manually.
For additional information, see Software Advisory for CSCvc63989.
SPA514G devices become unresponsive.
If affected, devices on the network will need to be manually restarted.
