Cisco Adaptive Security Appliance (ASA) and PIX MGCP denial of service
| cisco-asa-pix-mgcp-dos (37259) |  Low Risk |
Description:
Cisco Adaptive Security Appliance (ASA) and PIX security appliances are vulnerable to a denial of service, caused by the improper handling of malformed MGCP packets. If the Media Gateway Control Protocol (MGCP) application layer protocol inspection feature is enabled, a remote attacker could send specially-crafted MGCP packets to UDP port 2427 to cause the device to reload, resulting in a denial of service.
Platforms Affected:
- Cisco, Adaptive Security Appliance 7.0
- Cisco, Adaptive Security Appliance 7.1
- Cisco, Adaptive Security Appliance 7.2
- Cisco, Adaptive Security Appliance 8.0
- Cisco, PIX Firewall 7.0
- Cisco, PIX Firewall 7.1
- Cisco, PIX Firewall 7.2
- Cisco, PIX Firewall 8.0
Remedy:
Refer to cisco-sa-20071017-asa for patch, upgrade or suggested workaround information. See References.
Consequences:
Denial of Service
