Summary

The TLS implementation in HPE Integrated Lights-Out 3 (aka iLO3) firmware before 1.88 does not properly use a MAC protection mechanism in conjunction with CBC padding, which allows remote attackers to obtain sensitive information via a padding-oracle attack, aka a Vaudenay attack.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Signature Spoofing by Key Recreation
    An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.
