AI Analysis

Impact

The vulnerability is an authentication bypass (CWE‑288) in the AOS‑8 SSH daemon that allows an unauthenticated remote attacker to circumvent normal authentication controls. Upon successful exploitation, the attacker gains administrative privileges, enabling a full compromise of the host. This flaw undermines the confidentiality and integrity of the system and renders its SSH service ineffective in preventing unauthorized access.

Affected Systems

HPE AOS‑8 SSH daemon is affected. No specific version information is provided in the CVE data.

Risk and Exploitability

The CVSS score of 9.8 indicates critical severity. The EPSS score of < 1% indicates a very low but nonzero probability of exploitation, and the vulnerability is not listed in the CISA KEV catalog, suggesting no publicly known exploitation at present. The likely attack vector is remote via SSH, where an unauthenticated attacker may obtain full control after bypassing the authentication mechanism.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Check for vendor patch or upgrade for HPE AOS‑8 that addresses the SSH authentication bypass and apply it immediately.
  • Restrict SSH access by configuring firewall rules to allow only trusted IP addresses or network segments, thereby reducing exposure.
  • Monitor SSH logs for suspicious authentication attempts and block offending IPs; consider disabling the SSH service if it is not essential to operations.
