Description Preview

Multiple buffer overflow vulnerabilities (CWE-120) have been identified in several underlying services of Aruba Networks devices. These vulnerabilities can be exploited by sending specially crafted packets to the PAPI (Aruba's access point management protocol) UDP port (8211). An unauthenticated remote attacker can exploit these vulnerabilities to execute arbitrary code with privileged user permissions on the underlying operating system. This poses a significant security risk to affected Aruba Networks infrastructure.

Overview

The vulnerabilities affect the PAPI protocol implementation in Aruba Networks devices. PAPI is Aruba's proprietary access point management protocol that operates on UDP port 8211. The buffer overflow vulnerabilities exist in multiple underlying services that process PAPI protocol data. When exploited, these vulnerabilities allow an attacker to send specially crafted packets that can overflow buffers in the affected services, leading to arbitrary code execution with privileged user permissions. Since the vulnerability can be exploited remotely without authentication, it represents a critical security risk for organizations using affected Aruba Networks products.

Remediation

Organizations using Aruba Networks devices should:

  1. Immediately update all affected devices to the latest firmware versions as specified in the Aruba PSA-2023-006 advisory.
  2. If immediate patching is not possible, implement network segmentation to restrict access to the PAPI UDP port (8211).
  3. Monitor network traffic for suspicious activity targeting UDP port 8211.
  4. Consider implementing additional network security controls such as firewalls and intrusion detection/prevention systems to detect and block potential exploitation attempts.
  5. Follow Aruba Networks' specific mitigation guidance provided in their security advisory.
  6. Perform a security assessment to verify that all affected devices have been properly patched.
