Authentication Bypass in HPE Server Firmware

Publication date: 2026-09-01

Last updated on: 2026-09-03

Assigner: Hewlett Packard Enterprise (HPE)

Description

Vulnerabilities exist in the authentication module that may improperly process malformed or truncated input. An authenticated remote attacker could exploit these vulnerabilities by providing specially crafted input from a compromised or hostile authentication server. Successful exploitation could result in a Denial-of-Service or potential remote code execution with elevated privileges.

Attack-Flow Graph

Executive Summary

This vulnerability involves flaws in the authentication module that fail to properly handle malformed or incomplete input data. An attacker with authentication access could send specially crafted data from a compromised authentication server to trigger these issues.

Detection Guidance

Detecting this vulnerability requires monitoring for unusual authentication server behavior or malformed input processing. Check authentication logs for repeated failed attempts or unexpected input patterns. Use network traffic analysis tools like tcpdump or Wireshark to inspect authentication traffic for anomalies. Ensure your authentication module logs are enabled and review them for errors related to malformed input or crashes.

Impact Analysis

Exploitation could lead to a Denial-of-Service attack disrupting services or remote code execution allowing an attacker to gain elevated privileges on affected systems.

Compliance Impact

This vulnerability could lead to unauthorized access or disruption of systems handling sensitive data, which may violate GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information. Exploitation risks include remote code execution with elevated privileges, potentially exposing regulated data.

Mitigation Strategies

Implement strict input validation for authentication requests to detect malformed or truncated input. Monitor authentication server logs for suspicious activity or unexpected input patterns. Ensure authentication servers are updated with the latest patches to address known vulnerabilities.
