CVE-2024-5718
📋 TL;DR
CVE-2024-5718 is an unauthenticated remote code execution vulnerability in Logsign Unified SecOps Platform's cluster HTTP API. Attackers can execute arbitrary code as root without authentication, affecting all deployments with the vulnerable API enabled. Organizations using Logsign Unified SecOps Platform are at risk.
💻 Affected Systems
- Logsign Unified SecOps Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root-level access, data exfiltration, ransomware deployment, and persistent backdoor installation.
Likely Case
Initial foothold leading to lateral movement within the network, credential harvesting, and deployment of additional malware.
If Mitigated
Limited impact if proper network segmentation and access controls prevent exploitation attempts.
🎯 Exploit Status
No authentication required and the vulnerability is in a network-accessible API, making exploitation straightforward for attackers with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.4.8
Vendor Advisory: https://support.logsign.net/hc/en-us/articles/19316621924754-03-06-2024-Version-6-4-8-Release-Notes
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Download Logsign Unified SecOps Platform version 6.4.8 from official sources. 3. Follow vendor upgrade instructions to apply the patch. 4. Restart the Logsign service. 5. Verify the update was successful.
🔧 Temporary Workarounds
Disable Cluster HTTP API
linuxDisable the vulnerable cluster HTTP API if not required for operations
Consult Logsign documentation for disabling the cluster API service
Network Access Control
linuxRestrict access to TCP port 1924 using firewall rules
iptables -A INPUT -p tcp --dport 1924 -j DROP
ufw deny 1924/tcp
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Logsign systems from untrusted networks
- Deploy intrusion detection/prevention systems to monitor and block exploitation attempts on port 1924
🔍 How to Verify
Check if Vulnerable:
Check if Logsign version is below 6.4.8 and if TCP port 1924 is listening and accessibleCheck Version:
Check Logsign web interface or configuration files for version informationVerify Fix Applied:
Verify Logsign version is 6.4.8 or higher and test that unauthorized access to the cluster API is blocked📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to cluster API endpoints
- Unusual process execution from Logsign services
- Failed authentication attempts to port 1924
Network Indicators:
- Unusual traffic to TCP port 1924 from unexpected sources
- HTTP requests to cluster API without authentication headers
SIEM Query:
source_port:1924 AND (http_method:POST OR http_method:PUT) AND NOT user_agent:"Logsign"
