: The OSPFv2 routing protocol specified in RFC 2328 has an ambiguity that can be exploited and allow for traffic to be black-holed and/or redirected. A PTF is provided.
VULNERABILITY DETAILS:
DESCRIPTION:
A potential protocol vulnerability has been identified in the OSPFv2 Layer-3 routing protocol. If an attacker sends a specially crafted OSPFv2 Link State Advertisement (LSA) packet, it may result in the corruption of routing tables. The attack does not require local network access or physical access to the network and is therefore remotely exploitable, but specialized knowledge and techniques are required to execute this attack. A successful exploit will not impact integrity of transmitted data, but the availability of the network may be affected. Moreover, confidentiality of information may be compromised, although the attacker would not have control over what can be accessed.
