CVE-2025-59739 is a critical operating system command injection vulnerability identified in AndSoft's e-TMS version 25.03. The vulnerability arises from improper neutralization of special elements in user-supplied input, specifically related to the 'm' parameter in the '/clt/LOGINFRM_original.ASP' endpoint. An attacker can exploit this flaw by sending a crafted POST request containing malicious input in the 'm' parameter, which is then unsafely incorporated into operating system commands executed on the server. This lack of input validation or sanitization allows arbitrary command execution at the operating system level without requiring authentication or user interaction. The vulnerability is classified under CWE-77, indicating improper neutralization of special elements used in a command, commonly known as command injection. The CVSS 4.0 base score of 9.3 (critical) reflects the high severity, with attack vector being network-based, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. Exploitation could lead to full system compromise, data theft, service disruption, or pivoting within the affected network. Although no known exploits are reported in the wild yet, the ease of exploitation and critical impact make this a significant threat. The vulnerability affects a specific version (v25.03) of the e-TMS product, which is a transport management system software developed by AndSoft, likely used by logistics and transportation companies to manage operations.

For European organizations, especially those in the logistics, transportation, and supply chain sectors using AndSoft e-TMS v25.03, this vulnerability poses a severe risk. Successful exploitation could lead to unauthorized remote code execution on critical servers, resulting in data breaches, operational disruptions, and potential ransomware deployment. Given the central role of transport management systems in coordinating shipments and fleet management, an attack could cause cascading effects on supply chains, impacting delivery schedules and business continuity. Confidential information such as shipment details, client data, and internal communications could be exposed or altered, undermining trust and compliance with data protection regulations like GDPR. Additionally, disruption of transport management services could have economic repercussions and damage reputations. The lack of authentication or user interaction required for exploitation increases the risk of automated attacks and widespread impact if the vulnerable systems are internet-facing or accessible within corporate networks.

Organizations should immediately identify and inventory all instances of AndSoft e-TMS v25.03 within their environment. Since no official patches are currently available, implement the following mitigations: 1) Restrict network access to the vulnerable endpoint '/clt/LOGINFRM_original.ASP' by applying firewall rules or network segmentation to limit exposure to trusted internal IPs only. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the 'm' parameter, focusing on command injection patterns such as shell metacharacters or command chaining operators. 3) Conduct thorough input validation and sanitization at the application layer if source code access and modification are possible, ensuring special characters are neutralized or disallowed. 4) Monitor server logs and network traffic for anomalous POST requests or unexpected command execution indicators. 5) Prepare incident response plans specific to this vulnerability, including rapid isolation and forensic analysis procedures. 6) Engage with AndSoft for updates on patches or official remediation guidance and plan for prompt deployment once available. 7) Consider deploying endpoint detection and response (EDR) solutions on servers hosting e-TMS to detect post-exploitation activities.
