CVE-2013-4786

CVE-2013-4786 is an IPMI 2.0 vulnerability where RAKP authentication can leak HMAC data, enabling an attacker with IPMI network access to obtain password hashes and potentially hijack or replay BMC sessions. CERT notes that an unauthenticated attacker on the BMC network can predict session identi...

CVE-2013-4784

The CVE-2013-4784 vulnerability affects HP iLO BMC implementations and enables remote attackers to bypass authentication and execute arbitrary IPMI commands by triggering cipher suite 0 (cipher zero) with any password. The issue is a cipher-zero authentication bypass over IPMI, allowing network-a...
