Feb 08, 2017
- Headend System Releases
Known Affected Releases
Symptom: A vulnerability in the Transmission Control Protocol (TCP) module of the Cisco Headend System product could allow an unauthenticated, remote attacker to disable TCP ports and cause an increase in Central Processing Unit (CPU) and memory usage when the TCP connection is closing. The vulnerability is due to a lack of rate limiting in the TCP application. An attacker could exploit this vulnerability by when sending a flood of packets or denial-of-service (DOS) traffic stream. An exploit could allow the attacker to block TCP ports and exhaust system resources like CPU and memory when TCP connections are closing down. Conditions: Device running with default configuration running an affected version of software.
