CVE-2025-59737: Andsoft E-tms RCE Vulnerability

CVE-2025-59737 Overview

CVE-2025-59737 is a critical operating system command injection vulnerability affecting AndSoft's e-TMS transportation management system version 25.03. This vulnerability allows an unauthenticated attacker to execute arbitrary operating system commands on the server by sending a specially crafted POST request to the /clt/LOGINFRM_LXA.ASP endpoint, specifically targeting the m parameter.

Critical Impact

Unauthenticated attackers can achieve full remote code execution on vulnerable e-TMS servers, potentially compromising the entire transportation management infrastructure including sensitive logistics data, customer information, and connected systems.

Technical Details for CVE-2025-59737

Vulnerability Analysis

This command injection vulnerability (CWE-77, CWE-78) exists in the login functionality of AndSoft e-TMS. The application fails to properly sanitize user-supplied input in the m parameter when processing POST requests to /clt/LOGINFRM_LXA.ASP. Because the vulnerable endpoint is part of the login form, no authentication is required to exploit this flaw, significantly increasing the risk exposure.

The vulnerability enables network-based attacks that can be executed without any user interaction. An attacker who successfully exploits this vulnerability can gain complete control over the affected server, execute arbitrary commands with the privileges of the web application, access or modify sensitive business data, and potentially pivot to other systems within the network.

Root Cause

The root cause of CVE-2025-59737 is improper input validation and insufficient sanitization of the m parameter in the ASP-based login handler. The application directly incorporates user-controlled input into system commands without proper escaping or validation, creating a classic command injection scenario. This type of vulnerability typically occurs when developers use functions that pass user input to shell interpreters without adequate filtering of metacharacters and command separators.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker can exploit this vulnerability by crafting a malicious POST request to the vulnerable endpoint /clt/LOGINFRM_LXA.ASP with command injection payloads embedded in the m parameter.

A typical attack would involve sending specially crafted input containing command separators (such as |, ;, &, or newline characters) followed by arbitrary OS commands. The server would then execute these commands in the context of the web application, which often runs with elevated privileges.

The vulnerability can be exploited remotely from any network location that can reach the e-TMS web interface, making internet-exposed instances particularly vulnerable. For more technical details, see the INCIBE CERT Security Notice.

Detection Methods for CVE-2025-59737

Indicators of Compromise

• Suspicious POST requests to /clt/LOGINFRM_LXA.ASP containing shell metacharacters or unusual patterns in the m parameter
• Unexpected child processes spawned by the IIS worker process or ASP engine
• Anomalous outbound network connections from the e-TMS server to unknown external hosts
• Unusual file system modifications or creation of unauthorized files in web directories
• Evidence of data exfiltration or lateral movement originating from the e-TMS server

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block command injection patterns in POST requests to the affected endpoint
• Monitor IIS access logs for unusual requests to /clt/LOGINFRM_LXA.ASP with suspicious parameter values
• Deploy endpoint detection solutions to identify anomalous process execution chains originating from web server processes
• Configure SIEM rules to correlate web request logs with process creation events on e-TMS servers

Monitoring Recommendations

• Enable detailed logging for all requests to the e-TMS application, particularly the login endpoints
• Monitor for process execution events where w3wp.exe or similar web server processes spawn command interpreters (cmd.exe, powershell.exe)
• Implement network traffic analysis to detect potential command-and-control communications from compromised servers
• Establish baseline behavior for the e-TMS application and alert on deviations

How to Mitigate CVE-2025-59737

Immediate Actions Required

• Restrict network access to the e-TMS application to trusted IP addresses only using firewall rules
• Implement WAF rules to block requests containing command injection patterns targeting the vulnerable endpoint
• Consider taking the e-TMS instance offline if it is internet-facing until a patch is available
• Audit e-TMS servers for signs of compromise and review access logs for suspicious activity

Patch Information

Organizations should consult the INCIBE CERT Security Notice for the latest information on patches and updates from AndSoft. Contact the vendor directly for remediation guidance and patch availability for e-TMS version 25.03.

Workarounds

• Deploy a reverse proxy or web application firewall in front of the e-TMS application to filter malicious input
• Implement strict input validation at the network perimeter to block requests with shell metacharacters
• Restrict access to the /clt/LOGINFRM_LXA.ASP endpoint to known trusted sources only
• Isolate the e-TMS server in a network segment with limited connectivity to reduce the impact of potential compromise

# Example: Block suspicious requests at web server level (IIS URL Rewrite)
# Add to web.config in the e-TMS application root
# This is a temporary workaround - apply vendor patches when available

# Monitor for exploitation attempts in IIS logs
# Look for patterns like: ; | & ` $( in the m parameter
LogParser "SELECT date, time, cs-uri-stem, cs-uri-query FROM u_ex*.log WHERE cs-uri-stem LIKE '%LOGINFRM_LXA%'"
