CVE-2025-25872
📋 TL;DR
A privilege escalation vulnerability in Open Panel v0.3.4 allows remote attackers to gain elevated privileges through the Fix Permissions function. This affects systems running the vulnerable version of Open Panel, potentially allowing attackers to compromise administrative control.
💻 Affected Systems
- Open Panel
📦 What is this software?
Openpanel by Openpanel
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative privileges, allowing data theft, service disruption, or installation of persistent backdoors.
Likely Case
Unauthorized administrative access to the Open Panel interface, enabling configuration changes, user management, and potential lateral movement.
If Mitigated
Limited impact if proper network segmentation and least privilege principles are implemented, restricting the attacker's ability to move beyond the panel.
🎯 Exploit Status
Exploit details are publicly available on Packet Storm, suggesting weaponization is likely. Authentication is required to access the vulnerable function.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.3.5
Vendor Advisory: https://openpanel.com/docs/changelog/0.3.5/#%EF%B8%8F-security-fixes
Restart Required: Yes

🔧 Temporary Workarounds
Disable Fix Permissions Function
linuxTemporarily disable or restrict access to the vulnerable Fix Permissions function until patching can be completed.
# Edit Open Panel configuration to remove/disable Fix Permissions feature
# Consult Open Panel documentation for specific configuration options
Network Access Control
linuxRestrict network access to Open Panel administration interface to trusted IP addresses only.
# Example using iptables: iptables -A INPUT -p tcp --dport [OPEN_PANEL_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [OPEN_PANEL_PORT] -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Open Panel from critical systems
- Enable detailed logging and monitoring for privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check Open Panel version: grep 'version' /path/to/openpanel/config or check web interface. If version is 0.3.4, system is vulnerable.
Check Version:
grep -i version /opt/openpanel/config/settings.conf || openpanel --version
Verify Fix Applied:
After updating, verify version shows 0.3.5 and test that Fix Permissions function no longer allows privilege escalation.
