AI Analysis

Impact

An unauthenticated remote attacker can circumvent the proper authentication controls of the AOS‑S management interface if certain external preconditions are satisfied. By exploiting this flaw the attacker gains unauthorized access to the switch’s management functions. The result is privilege escalation to the level of the switch’s administrative interface, allowing configuration changes, network traffic inspection, or further lateral movement.

Affected Systems

The vulnerability affects Hewlett Packard Enterprise’s AOS‑S Switch. No specific firmware or software version numbers are listed in the advisory, so all revisions that employ the described management interface are potentially impacted. The flaw resides specifically in the remote management layer of the switch.

Risk and Exploitability

The CVSS base score of 9.8 indicates a critical severity, and the absence of an EPSS score means the exploit probability is currently unknown. Because exploiting the weakness requires an unauthenticated remote attack with no prerequisite user interaction, it is deemed a high‑risk threat vector. Although not listed in CISA’s KEV catalog yet, the vulnerability’s critical score suggests that vendors and customers should address it promptly to prevent potential breaches.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest firmware or patch provided by HPE that addresses the authentication bypass in the AOS‑S management interface.
  • If an update is not yet available, limit the attack surface by restricting management access to a trusted internal network or subnet using ACLs or firewall rules.
  • Enable and enforce multi‑factor authentication on the AOS‑S management interface to add an additional layer of credential validation.
