CVE-2024-58287
📋 TL;DR
CVE-2024-58287 is an authenticated command injection vulnerability in reNgine 2.2.0 that allows attackers to execute arbitrary commands on the server. Attackers can inject malicious base64-encoded payloads into the nmap_cmd parameter during scan engine configuration to achieve remote code execution. This affects all organizations running vulnerable versions of reNgine with authenticated user access.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands with the privileges of the reNgine process, potentially leading to data theft, lateral movement, or persistent backdoors.
Likely Case
Attackers with authenticated access can execute commands to exfiltrate sensitive scan data, compromise the underlying server, or pivot to other systems in the network.
If Mitigated
With proper input validation and command sanitization, the vulnerability would be prevented, limiting attackers to legitimate scan functionality only.
🎯 Exploit Status
Exploit code is publicly available on Exploit-DB (ID 52081). Attack requires authenticated access but the exploit is straightforward once authentication is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.2.1 or later
Vendor Advisory: https://github.com/yogeshojha/rengine
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Update reNgine to version 2.2.1 or later. 3. Restart the reNgine service. 4. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
linuxImplement strict input validation for the nmap_cmd parameter to reject any commands containing shell metacharacters or suspicious patterns.
# Requires code modification to validate nmap_cmd input
# Example: if re.search(r'[;&|`$()]', nmap_cmd): reject
Restrict User Access
allLimit access to scan engine configuration to only trusted administrators using role-based access controls.
# Configure reNgine to restrict scan engine configuration to admin users only
🧯 If You Can't Patch
- Implement network segmentation to isolate reNgine instances from critical systems
- Enable detailed logging and monitoring for command execution attempts in scan configurations
🔍 How to Verify
Check if Vulnerable:
Check if running reNgine version 2.2.0 by examining the version in the web interface or configuration files.Check Version:
grep -i version /path/to/rengine/config/files or check web interfaceVerify Fix Applied:
Verify the version has been updated to 2.2.1 or later and test that command injection attempts in the nmap_cmd parameter are properly rejected.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns in reNgine logs
- Base64-encoded payloads in scan configuration requests
- Multiple failed authentication attempts followed by scan configuration changes
Network Indicators:
- Unexpected outbound connections from reNgine server
- Unusual scan traffic patterns
SIEM Query:
source="rengine" AND ("nmap_cmd" CONTAINS "base64" OR "command injection" OR suspicious shell characters in parameters)
