CVE-2025-1044
📋 TL;DR
This critical authentication bypass vulnerability allows remote attackers to completely bypass authentication on Logsign Unified SecOps Platform installations without any credentials. Attackers can gain unauthorized access to the security operations platform, potentially compromising the entire security monitoring infrastructure. All organizations running vulnerable versions of Logsign Unified SecOps Platform are affected.
💻 Affected Systems
- Logsign Unified SecOps Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the security operations platform, allowing attackers to disable security monitoring, exfiltrate sensitive security data, manipulate security alerts, and pivot to other internal systems.
Likely Case
Unauthorized access to security logs, configuration data, and potentially administrative functions, enabling attackers to disable security controls and hide malicious activity.
If Mitigated
Limited impact if platform is isolated in a security zone with strict network controls and access restrictions, though authentication bypass still represents significant risk.
🎯 Exploit Status
ZDI-CAN-25336 identifier suggests this was reported through coordinated disclosure. The high CVSS score and authentication bypass nature make weaponization highly probable.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.4.32
Vendor Advisory: https://support.logsign.net/hc/en-us/articles/22076844908946-18-10-2024-Version-6-4-32-Release-Notes
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Download version 6.4.32 from Logsign support portal. 3. Follow Logsign upgrade documentation for your deployment type. 4. Restart services after upgrade. 5. Verify authentication is working correctly.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to Logsign platform to only trusted IP addresses/networks
# Use firewall rules to restrict access
# Example: iptables -A INPUT -p tcp --dport 443 -s TRUSTED_IP -j ACCEPT
# Example: iptables -A INPUT -p tcp --dport 443 -j DROP
Web Application Firewall
allDeploy WAF with authentication bypass protection rules
# Configure WAF to detect and block authentication bypass attempts
# Enable authentication protection rules in your WAF solution
🧯 If You Can't Patch
- Isolate the Logsign platform in a dedicated security zone with strict network segmentation
- Implement multi-factor authentication at network level or through reverse proxy
🔍 How to Verify
Check if Vulnerable:
Check Logsign platform version via web interface or system logs. Versions prior to 6.4.32 are vulnerable.Check Version:
# Check via web interface: Login and navigate to System > About
# Or check system logs for version informationVerify Fix Applied:
After upgrading to 6.4.32, test authentication by attempting to access protected endpoints without credentials. Verify authentication is required.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful access without credentials
- Access to administrative endpoints from unexpected IP addresses
- Authentication logs showing bypass patterns
Network Indicators:
- HTTP requests to authentication endpoints with unusual parameters
- Direct access to protected resources without prior authentication requests
SIEM Query:
source="logsign" AND (event_type="auth" AND result="success" AND NOT username=*) OR (url_path="/admin/*" AND NOT referer="*/login*")
