Description (partial)

Symptom:
A vulnerability in the IPMI 2.0 specification used by Cisco Integrated Management Controller could allow an authenticated, remote attacker to conduct offline password guessing attacks.

The vulnerability is due to improper security restrictions provided by the RMCP Authenticated Key-Exchange (RAKP) Protocol. An authenticated, remote attacker could exploit the vulnerability by sending malicious authentication requests to the IPMI 2.0 protocol. Successful exploitation could allow the attacker to bypass authentication and gain unauthorized access to  the system, which could be used to conduct further attacks.

<B>Conditions:</B>
Cisco IMC running with IPMI Enabled.
