CVE-2023-0241
📋 TL;DR
CVE-2023-0241 is a directory traversal vulnerability in pgAdmin 4 that allows authenticated users to access or modify files outside the intended directory. This affects all pgAdmin 4 users running versions before 6.19, potentially enabling unauthorized changes to other users' settings or database configurations.
💻 Affected Systems
- pgAdmin 4
📦 What is this software?
Pgadmin 4 by Pgadmin
⚠️ Risk & Real-World Impact
Worst Case
An attacker could modify critical configuration files, alter database settings, or access sensitive system files, potentially leading to data corruption, privilege escalation, or complete system compromise.
Likely Case
Authenticated users could modify other users' pgAdmin settings, alter database connection configurations, or access files they shouldn't have permission to view.
If Mitigated
With proper network segmentation and access controls, impact is limited to the pgAdmin application scope, preventing lateral movement to other systems.
🎯 Exploit Status
Exploitation requires authenticated access to pgAdmin. Directory traversal techniques are well-documented and relatively simple to implement.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.19 and later
Vendor Advisory: https://github.com/pgadmin-org/pgadmin4/issues/5734
Restart Required: Yes
Instructions:
1. Backup current pgAdmin configuration and data. 2. Stop pgAdmin service. 3. Upgrade to pgAdmin 4 version 6.19 or later using package manager or manual installation. 4. Restart pgAdmin service. 5. Verify functionality.
🔧 Temporary Workarounds
Restrict Access Controls
allLimit pgAdmin access to trusted users only and implement strict authentication requirements
Network Segmentation
allPlace pgAdmin behind VPN or restrict network access to specific IP addresses
🧯 If You Can't Patch
- Implement strict access controls and limit pgAdmin to trusted administrative users only
- Monitor pgAdmin logs for unusual file access patterns or directory traversal attempts
🔍 How to Verify
Check if Vulnerable:
Check pgAdmin version via web interface (Help → About) or command line: pgadmin4 --versionCheck Version:
pgadmin4 --versionVerify Fix Applied:
Confirm version is 6.19 or higher and test directory traversal attempts are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual file path access patterns in pgAdmin logs
- Multiple failed directory traversal attempts
- Unexpected configuration changes
Network Indicators:
- HTTP requests containing '../' or similar path traversal patterns to pgAdmin endpoints
SIEM Query:
source="pgadmin" AND ("../" OR "..\\" OR "%2e%2e%2f")
