CVE-2025-59735
📋 TL;DR
This is a critical command injection vulnerability in AndSoft's e-TMS transportation management system. Attackers can execute arbitrary operating system commands on the server by sending specially crafted POST requests to the vulnerable '/clt/LOGINFRM.ASP' endpoint. All organizations using the affected e-TMS version are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Full server compromise leading to data theft, ransomware deployment, lateral movement to other systems, and complete system takeover.
Likely Case
Unauthorized command execution resulting in data exfiltration, installation of backdoors, or disruption of transportation management operations.
If Mitigated
Limited impact if proper network segmentation, WAF rules, and input validation are in place, though risk remains elevated.
🎯 Exploit Status
The vulnerability requires only a POST request to a specific endpoint with malicious parameters, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in available references
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/update-24092025-multiple-vulnerabilities-andsofts-e-tms
Restart Required: No
Instructions:
1. Contact AndSoft for patch availability 2. Apply any available security updates 3. Test in non-production environment first 4. Deploy to production systems
🔧 Temporary Workarounds
Web Application Firewall Rule
allBlock or sanitize requests containing command injection patterns in the 'm' parameter
WAF specific - configure rule to block POST requests to /clt/LOGINFRM.ASP with suspicious 'm' parameter values
Input Validation Filter
windowsImplement server-side validation to reject malicious input in the vulnerable parameter
ASP code modification: Add input validation for the 'm' parameter to reject shell metacharacters
🧯 If You Can't Patch
- Network segmentation: Isolate e-TMS servers from internet and restrict access to authorized users only
- Implement strict input validation and output encoding for all user-supplied data
🔍 How to Verify
Check if Vulnerable:
Check if e-TMS version is v25.03 and if /clt/LOGINFRM.ASP endpoint accepts POST requests with 'm' parameterCheck Version:
Check application version in administrative interface or configuration filesVerify Fix Applied:
Test with controlled payloads to confirm command injection is no longer possible📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /clt/LOGINFRM.ASP
- Commands with shell metacharacters in 'm' parameter
- Unexpected system command execution logs
Network Indicators:
- POST requests to vulnerable endpoint with suspicious parameter values
- Outbound connections from e-TMS server to unexpected destinations
SIEM Query:
source="e-tms" AND (url="/clt/LOGINFRM.ASP" AND method="POST" AND (param="m" AND value MATCHES "[;&|`$()]"))
