CVE-2025-25039

4.7 MEDIUM

📋 TL;DR

This vulnerability in HPE Aruba ClearPass Policy Manager allows authenticated remote attackers to execute arbitrary commands on the underlying host with lower privileges. It affects organizations using ClearPass Policy Manager for network access control and policy management. Attackers need valid credentials to exploit this command injection flaw.

💻 Affected Systems

Products:
  • HPE Aruba Networking ClearPass Policy Manager
Versions: All versions prior to 6.12.8, 6.13.4, and 6.14.0
Operating Systems: Linux-based ClearPass OS
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated access to the web management interface. ClearPass deployments with internet-facing management interfaces are at higher risk.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

An attacker with valid credentials could gain persistent access to the ClearPass host, pivot to other systems, steal sensitive authentication data, or disrupt network access control services.

🟠

Likely Case

Privilege escalation leading to unauthorized access to the ClearPass system, potential data exfiltration of authentication credentials and policies, and disruption of network access services.

🟢

If Mitigated

Limited impact with proper network segmentation, strong authentication controls, and monitoring in place, potentially contained to the ClearPass system only.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires valid credentials. The CWE-78 (OS Command Injection) suggests straightforward exploitation once authenticated.

🔧 Temporary Workarounds

Restrict Management Interface Access

all

Limit access to ClearPass web management interface to trusted IP addresses only

Configure firewall rules to restrict TCP/443 access to management IP ranges

Enforce Strong Authentication

all

Implement multi-factor authentication for all ClearPass administrative accounts

Enable MFA in ClearPass Policy Manager authentication settings

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate ClearPass management interface
  • Enforce principle of least privilege for all ClearPass user accounts and monitor for suspicious activity

🔍 How to Verify

Check if Vulnerable:

Check ClearPass version via web interface (Admin > Support > About) or CLI command 'appliance version'

Check Version:

appliance version

Verify Fix Applied:

Verify version is 6.12.8, 6.13.4, or 6.14.0 or higher using same methods

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution patterns in system logs
  • Multiple failed authentication attempts followed by successful login
  • Suspicious process creation from web interface user context

Network Indicators:

  • Unusual outbound connections from ClearPass server
  • Anomalous traffic patterns to/from management interface

SIEM Query:

source="clearpass" AND (event_type="command_execution" OR user="webui" AND process="bash")
