CVE-2024-4215

7.4 HIGH

📋 TL;DR

This vulnerability allows attackers who have stolen valid pgAdmin credentials to bypass multi-factor authentication (MFA) protections. Affected systems running pgAdmin 8.5 or earlier are vulnerable, enabling unauthorized database management and SQL execution. This impacts organizations using pgAdmin with MFA enabled for database administration.

💻 Affected Systems

Products:
  • pgAdmin
Versions: <= 8.5
Operating Systems: All platforms running pgAdmin
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects installations with MFA enabled. Systems without MFA are not vulnerable to this specific bypass.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers with stolen credentials gain full administrative access to PostgreSQL databases, allowing data theft, destruction, or ransomware deployment.

🟠

Likely Case

Credential theft leads to unauthorized database access and potential data exfiltration or manipulation.

🟢

If Mitigated

With strong credential protection and network segmentation, impact is limited to specific database instances.

🌐 Internet-Facing: HIGH - Internet-exposed pgAdmin instances are prime targets for credential stuffing and MFA bypass attacks.
🏢 Internal Only: MEDIUM - Internal attackers or compromised accounts can bypass MFA to escalate privileges.

🎯 Exploit Status

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

Requires valid username/password credentials. Attack is straightforward once credentials are obtained.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 8.6 or later

Vendor Advisory: https://github.com/pgadmin-org/pgadmin4/issues/7425

Restart Required: Yes

Instructions:

1. Backup pgAdmin configuration and data. 2. Upgrade to pgAdmin 8.6 or later. 3. Restart pgAdmin service. 4. Verify MFA is functioning correctly.

🔧 Temporary Workarounds

Disable MFA temporarily

all

Disable multi-factor authentication until patching is complete

Edit pgAdmin config to disable MFA: set ENABLE_MFA = False in config_local.py

Network isolation

linux

Restrict access to pgAdmin interface using firewall rules

iptables -A INPUT -p tcp --dport 5050 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 5050 -j DROP

🧯 If You Can't Patch

  • Implement strict network access controls to limit pgAdmin access to trusted IPs only
  • Enforce strong password policies and monitor for credential compromise

🔍 How to Verify

Check if Vulnerable:

Check pgAdmin version: if version <= 8.5 and MFA is enabled, system is vulnerable.

Check Version:

pgadmin4 --version or check web interface footer

Verify Fix Applied:

After upgrade, test MFA functionality by attempting login with valid credentials - should require MFA code.

📡 Detection & Monitoring

Log Indicators:

  • Successful logins without MFA verification in pgAdmin logs
  • Multiple failed MFA attempts followed by successful login

Network Indicators:

  • Unusual database query patterns from pgAdmin interface
  • SQL queries from unexpected IP addresses

SIEM Query:

source="pgadmin.log" AND (event="login_success" AND NOT mfa_verified="true")
