CVE-2013-1350
📋 TL;DR
Verax NMS prior to version 2.1.0 contains multiple security bypass vulnerabilities that allow attackers to circumvent authentication and authorization controls. This affects organizations using Verax Network Management System for monitoring network infrastructure. Attackers could gain unauthorized access to sensitive network management functions.
💻 Affected Systems
- Verax Network Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of network management system leading to unauthorized configuration changes, service disruption, and potential lateral movement into managed network devices.
Likely Case
Unauthorized access to network monitoring data, configuration viewing/modification, and potential privilege escalation within the NMS.
If Mitigated
Limited impact with proper network segmentation and access controls preventing external access to the NMS interface.
🎯 Exploit Status
Multiple authentication bypass methods exist. Exploitation requires network access to the NMS web interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.1.0 or later
Vendor Advisory: No official vendor advisory found in provided references
Restart Required: Yes
Instructions:
1. Download Verax NMS version 2.1.0 or later from vendor. 2. Backup current configuration and data. 3. Stop Verax NMS services. 4. Install updated version. 5. Restart services. 6. Verify functionality.
🔧 Temporary Workarounds
Network Segmentation
linuxRestrict access to Verax NMS web interface to trusted management networks only
iptables -A INPUT -p tcp --dport [NMS_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [NMS_PORT] -j DROP
Web Application Firewall
allDeploy WAF with authentication bypass protection rules
🧯 If You Can't Patch
- Implement strict network access controls to limit NMS access to authorized administrators only
- Monitor authentication logs for suspicious activity and failed login attempts
🔍 How to Verify
Check if Vulnerable:
Check Verax NMS version via web interface admin panel or configuration files. Versions below 2.1.0 are vulnerable.Check Version:
Check web interface footer or /opt/verax/version.txt on Linux systemsVerify Fix Applied:
Verify version is 2.1.0 or higher and test authentication mechanisms work properly.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful access
- Access from unusual IP addresses without authentication logs
- Configuration changes from unauthenticated users
Network Indicators:
- HTTP requests bypassing authentication endpoints
- Unusual traffic patterns to NMS web interface
