CVE-2012-3460
📋 TL;DR
CVE-2012-3460 is a critical vulnerability in Cumin (a systems management tool) where the PostgreSQL database user is created without a password during installation. This allows unauthenticated attackers to gain full database access, potentially leading to complete system compromise. Systems running vulnerable versions of Cumin with PostgreSQL are affected.
💻 Affected Systems
- Cumin (Red Hat systems management tool)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover: attackers can execute arbitrary SQL commands, steal sensitive data, modify configurations, and potentially escalate to root privileges on the host system.
Likely Case
Unauthenticated database access leading to data theft, configuration manipulation, and potential privilege escalation within the database environment.
If Mitigated
Minimal impact if proper network segmentation, authentication controls, and least privilege principles are implemented.
🎯 Exploit Status
Simple SQL connection attempts can exploit this vulnerability. No special tools or techniques required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisories for specific patched versions
Vendor Advisory: https://access.redhat.com/security/cve/cve-2012-3460
Restart Required: Yes
Instructions:
1. Update Cumin packages via yum: 'yum update cumin*' 2. Restart Cumin services 3. Set password for PostgreSQL cumin user if not done automatically
🔧 Temporary Workarounds
Set PostgreSQL password manually
linuxManually set a strong password for the Cumin PostgreSQL user
sudo -u postgres psql -c "ALTER USER cumin WITH PASSWORD 'strong_password';"
Update Cumin configuration to use the new password
Network isolation
linuxRestrict PostgreSQL port (5432) access to only trusted hosts
iptables -A INPUT -p tcp --dport 5432 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 5432 -j DROP
🧯 If You Can't Patch
- Immediately set a strong password for the Cumin PostgreSQL user using ALTER USER command
- Implement strict network access controls to limit PostgreSQL port access to only necessary systems
🔍 How to Verify
Check if Vulnerable:
Attempt to connect to PostgreSQL as 'cumin' user without password: 'psql -U cumin -h localhost -d cumin'Check Version:
rpm -qa | grep cuminVerify Fix Applied:
Verify connection requires password: 'psql -U cumin -h localhost -d cumin' should fail without password📡 Detection & Monitoring
Log Indicators:
- PostgreSQL logs showing successful connections from 'cumin' user without authentication
- Failed authentication attempts after password is set
Network Indicators:
- Unexpected connections to PostgreSQL port 5432
- SQL queries from unauthorized sources
SIEM Query:
source="postgresql" AND (event="authentication succeeded" AND user="cumin") OR (event="connection authorized" AND user="cumin")
