AI Analysis

Impact

Buffer overflow in a vulnerable interface of HPE AOS‑S allows unauthenticated remote attackers to read sensitive memory contents and can also cause the device to crash. The flaw is reflected in a CVSS score of 9.1, indicating a high severity and significant potential impact on confidentiality, integrity, and availability. It is categorized under exploitation of improperly restricted operations within a memory buffer and exposure of information, aligning with the identified CWEs.

Affected Systems

The vulnerability affects Hewlett Packard Enterprise AOS‑S Switches. No specific affected versions are listed in the data. Administrators should assume that all deployed AOS‑S builds are potentially impacted unless a patch or advisory explicitly indicates otherwise.

Risk and Exploitability

The CVSS rating of 9.1 places the issue in the high‑impact range. Although an EPSS score is not available, the absence of a KEV listing does not diminish the need for a quick response. Attackers can reach the vulnerable interface over the network without authentication, exploit the buffer overflow to read memory, and potentially trigger a denial of service. No public exploitation reports are cited, but the high severity and remote nature of the attack vector warrant immediate remedial action.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the HPE‑issued firmware or patch that addresses the buffer‑overflow flaw in AOS‑S Switches
  • Restrict or disable the vulnerable interface to authenticated users only, enforcing network segmentation or firewall rules around it
  • Monitor system logs for abnormal memory access patterns or repeated crashes and restart the device when required
