Description Preview

Multiple command injection vulnerabilities (CWE-77) have been identified in Aruba Networks devices that could lead to unauthenticated remote code execution. An attacker can exploit these vulnerabilities by sending specially crafted packets to the PAPI (Aruba Networks access point management protocol) UDP port 8211. Successful exploitation allows execution of arbitrary code with privileged user permissions on the underlying operating system, potentially leading to complete system compromise.

Overview

The vulnerabilities affect the PAPI protocol implementation in Aruba Networks devices. PAPI (Port 8211/UDP) is Aruba's proprietary protocol used for access point management. The command injection vulnerabilities allow malicious actors to bypass authentication and inject commands that execute with elevated privileges. This represents a critical security risk as attackers can gain complete control over affected devices without requiring any authentication credentials. The vulnerability is particularly concerning for networks with Aruba infrastructure exposed to untrusted networks.

Remediation

  1. Update all affected Aruba Networks devices to the latest firmware versions that contain patches for these vulnerabilities.
  2. Implement network segmentation to restrict access to the PAPI UDP port (8211).
  3. Configure firewall rules to block external access to port 8211/UDP.
  4. Monitor network traffic for suspicious activity targeting UDP port 8211.
  5. Follow Aruba Networks' security advisories for specific patch information and additional mitigation strategies.
  6. Conduct a security audit to ensure no unauthorized access has occurred through this vulnerability.
