VULNERABILITY SUMMARY
Multiple security vulnerabilities have been identified in Integrated Lights-Out
3 (iLO 3), and Integrated Lights-Out 5 (iLO 5) firmware. The vulnerabilities
could be remotely exploited to execute code, cause denial of service, and
expose sensitive information. HPE has released updated firmware to mitigate
these vulnerabilities.
Note: These vulnerabilities are collectively named Ripple20. iLO 3 and iLO 5
are only exposed to a portion of the Ripple20 vulnerabilities. HPE has modified
the reported Ripple20 CVSS scores and vectors to reflect product engineering's
vulnerability assessment.
