Vulnerability Note VU#486224
Multiple Cisco ONS control cards fail to properly handle malformed UDP packets
A vulnerability exists in multiple control cards used by Cisco ONS devices. This vulnerability could allow a remote attacker to cause a denial-of-service condition.
Cisco's Optical Networking product line consists of a series of devices designed to offer high-bandwidth data services. These optical devices are managed through a series of control cards, which vary depending on the model of the device. There is a vulnerability in the way the XTC, TCC/TCC+/TCC2, TCCi/TCC2, and TSC control cards handle malformed UDP packets. By sending specially crafted UDP packets to a vulnerable optical device, a remote attacker could cause the control cards to reset.
A remote, unauthenticated attacker could cause control cards to reset on an affected optical device. Repeated exploitation of this vulnerability could result in a denial of service.
