Discussion
Cisco IOS Multi Protocol Label Switching Remote Denial Of Service Vulnerability
Cisco IOS based routers that are configured with support for Multi Protocol Label Switching (MPLS) are reported prone to a remote denial of service vulnerability.
It is reported that the vulnerability presents itself when an affected router handles an unspecified malicious packet on a MPLS disabled interface.
A remote attacker that resides on the same network segment as the vulnerable router may exploit this vulnerability continuously to effectively deny network-based services to legitimate users.
