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, and TCCi/TCC2 control cards handle malformed IP packets. By sending specially crafted IP packets to a vulnerable optical device, a remote attacker could cause the control cards to reset.
