CVE-2022-25048
📋 TL;DR
CVE-2022-25048 is a command injection vulnerability in CentOS Web Panel (CWP) that allows authenticated users to execute arbitrary commands with root privileges. This affects CWP installations where normal user accounts exist, enabling privilege escalation to full system control. The vulnerability stems from improper input sanitization in web panel functions.
💻 Affected Systems
- CentOS Web Panel (CWP)
📦 What is this software?
Webpanel by Control Webpanel
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise - attacker gains root shell, installs persistent backdoors, exfiltrates all data, and uses the server for further attacks.
Likely Case
Attacker gains root access, installs cryptocurrency miners or ransomware, and compromises all hosted websites and databases.
If Mitigated
Limited impact if proper network segmentation and least privilege principles are implemented, though root access still provides significant control.
🎯 Exploit Status
Exploit requires authenticated user access but is straightforward to execute once credentials are obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.9.8.1127 and later
Vendor Advisory: https://github.com/Immersive-Labs-Sec/CentOS-WebPanel
Restart Required: No
Instructions:
1. Backup current configuration. 2. Update CWP using the built-in updater or manual update script. 3. Verify version is v0.9.8.1127 or higher.
🔧 Temporary Workarounds
Disable user account access
linuxTemporarily disable all non-admin user accounts until patching can be completed
# Edit user configuration files or disable via CWP admin interface
Network isolation
linuxRestrict access to CWP panel to trusted IP addresses only
iptables -A INPUT -p tcp --dport 2030 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 2030 -j DROP
🧯 If You Can't Patch
- Implement strict network access controls to limit CWP panel access to administrative IPs only
- Disable all non-essential user accounts and implement multi-factor authentication for remaining accounts
🔍 How to Verify
Check if Vulnerable:
Check CWP version via admin panel or run: cat /usr/local/cwpsrv/var/services/versionCheck Version:
