CVE-2013-4806
HighSummary
Implementacja OSPF w routerach HP JD9##A oraz przełącznikach HP J4###A, J484#B, J8###A, JD3##A, JE###A i JF55#A, a także w routerach i przełącznikach HP 3COM oraz HP H3C nie uwzględnia możliwości wystąpienia duplikatów wartości Link State ID w pakietach Link State Advertisement (LSA). To pozwala zdalnym uwierzytelnionym użytkownikom na wywołanie odmowy usługi (zakłócenie routingu) lub uzyskanie wrażliwych informacji o pakietach poprzez spreparowany pakiet LSA.
Risk Assessment
Organizacja może doświadczyć zakłóceń w routingu, co może prowadzić do przerw w dostępności usług. Dodatkowo, istnieje ryzyko ujawnienia wrażliwych informacji o pakietach.
Recommendation
Zaleca się aktualizację oprogramowania urządzeń do najnowszej wersji, która naprawia tę podatność oraz monitorowanie ruchu sieciowego w celu wykrycia potencjalnych ataków.

A vulnerability in the ash_authentication library (Elixir) allows an attacker who can plant a remember-me cookie in a victim's browser to replace the victim's authenticated session with one for the attacker's own account. The issue stems from a mismatch between the session keys used by the guard and the reader, causing remember-me sign-in to run on every request.
Original NVD description (English source)
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.
