CVE-2025-59739
📋 TL;DR
This is a critical command injection vulnerability in AndSoft's e-TMS transportation management software that allows unauthenticated attackers to execute arbitrary operating system commands on the server by sending a specially crafted POST request. All organizations using the vulnerable version of e-TMS are affected, potentially exposing their entire server infrastructure to compromise.

⚠️ Risk & Real-World Impact
Worst Case
Complete server takeover leading to data theft, ransomware deployment, lateral movement to other systems, and persistent backdoor installation.
Likely Case
Initial foothold on the server enabling reconnaissance, credential harvesting, and deployment of additional malware or persistence mechanisms.
If Mitigated
Limited impact if network segmentation, strict firewall rules, and proper monitoring are in place to detect and block exploitation attempts.
🎯 Exploit Status
The vulnerability requires sending a simple HTTP POST request with malicious payload in the 'm' parameter. No authentication is required, making exploitation trivial for attackers with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Update to latest version as specified in vendor advisory
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/update-24092025-multiple-vulnerabilities-andsofts-e-tms
Restart Required: Yes
Instructions:
1. Contact AndSoft for the latest patched version. 2. Backup current installation and data. 3. Apply the vendor-provided patch or upgrade to the fixed version. 4. Restart the e-TMS service and verify functionality.
🔧 Temporary Workarounds
Web Application Firewall Rule
allBlock or sanitize requests containing command injection patterns in the 'm' parameter
WAF specific configuration - block patterns like ;, |, &, $(), `, &&, || in POST parameters
Network Access Control
allRestrict access to the vulnerable endpoint using firewall rules
iptables -A INPUT -p tcp --dport 80 -m string --string "/clt/LOGINFRM_original.ASP" --algo bm -j DROP
netsh advfirewall firewall add rule name="Block e-TMS Vuln" dir=in action=block protocol=TCP localport=80 remoteip=any program="%SystemRoot%\system32\svchost.exe" service=HTTP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the e-TMS server from critical systems
- Deploy a web application firewall with specific rules to block command injection patterns in POST parameters
🔍 How to Verify
Check if Vulnerable:
Check if the endpoint '/clt/LOGINFRM_original.ASP' accepts POST requests with the 'm' parameter and responds to command injection payloads (test in controlled environment only)Check Version:
Check e-TMS version through application interface or consult vendor documentationVerify Fix Applied:
Verify the patched version no longer executes OS commands when malicious payloads are sent to the vulnerable endpoint📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to '/clt/LOGINFRM_original.ASP' with shell metacharacters in parameters
- Unexpected system command execution from web server process
- Failed authentication attempts followed by command execution patterns
Network Indicators:
- HTTP POST requests containing command injection patterns (;, |, &, `, $()) in the 'm' parameter
- Outbound connections from web server to unusual external IPs or ports
SIEM Query:
source="web_server" AND (url="/clt/LOGINFRM_original.ASP" AND method="POST" AND (param="m" AND value MATCHES "[;|&`$()]"))
