VAR-201401-0492
Vulnerability from variot - Updated: 2024-04-19 22:49The OSPF implementation on NEC IP38X, IX1000, IX2000, and IX3000 routers does not consider the possibility of duplicate Link State ID values in Link State Advertisement (LSA) packets before performing operations on the LSA database, which allows remote attackers to cause a denial of service (routing disruption) or obtain sensitive packet information via a crafted LSA packet, a related issue to CVE-2013-0149. This vulnerability CVE-2013-0149 And related issues. Supplementary information : CWE Vulnerability type by CWE-694: Use of Multiple Resources with Duplicate Identifier ( Using multiple resources with duplicate identifiers ) Has been identified. NEC IP38X, IX1000, IX2000 and IX3000 routers are router devices. The route is interrupted or sensitive message information is obtained. Multiple NEC Products are prone to a remote security-bypass vulnerability due to an error in the OSPF protocol specification. Exploiting this issue could allow an attacker to bypass certain security restrictions and take full control of the OSPF AS domain routing table, blackholed traffic, and intercepted traffic. This may aid in further attacks
