The OSPF implementation on HP JD9##A routers; HP J4###A, J484#B, J8###A, JD3##A, JE###A, and JF55#A switches; HP 3COM routers and switches; and HP H3C routers and switches 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 authenticated users 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 is a vulnerability exploitable with network access which means the vulnerable software is bound to
the network stack and the attacker does not require local network access or local access to exploit it.
Such a vulnerability is often termed “remotely exploitable”.
The access conditions are somewhat specialized; the following are examples:
The attacking party is limited to a group of systems or users at some level of authorization, possibly untrusted.
Some information must be gathered before a successful attack can be launched.
The affected configuration is non-default, and is not commonly configured (e.g., a vulnerability present when a
server performs user account authentication via a specific scheme, but not present for another authentication scheme).
The attack requires a small amount of social engineering that might occasionally fool cautious users (e.g.,
phishing attacks that modify a web browser’s status bar to show a false link, having to be on someone’s “buddy”
list before sending an IM exploit).
One instance of authentication is required to access and exploit the vulnerability.
There is considerable informational disclosure. Access to some system files is
possible, but the attacker does not have control over what is obtained, or the scope of
the loss is constrained. An example is a vulnerability that divulges only certain tables
in a database.
There is no impact to the integrity of the system.
There is a total shutdown of the affected resource. The attacker can render the
resource completely unavailable.
