CVE-2025-59764 is a reflected Cross-Site Scripting (XSS) vulnerability identified in AndSoft's e-TMS version 25.03, a transportation management system. The vulnerability arises from improper neutralization of input during web page generation, specifically involving the parameters 'l', 'demo', 'demo2', 'TNTLOGIN', 'UO', and 'SuppConn' within the '/clt/LOGINFRM_FCC.ASP' endpoint. An attacker can craft a malicious URL containing JavaScript code embedded in these parameters, which, when visited by a victim, executes in the victim's browser context. This execution can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The CVSS 4.0 base score is 5.1 (medium severity), reflecting that the attack vector is network-based, requires no privileges, no authentication, but does require user interaction (clicking the malicious link). The impact on confidentiality is low, with no impact on integrity or availability. No known exploits are currently reported in the wild. The vulnerability is classified under CWE-79, indicating improper input sanitization and output encoding issues in web applications. The lack of a patch link suggests that a fix may not yet be publicly available or disclosed at the time of reporting.

For European organizations using AndSoft e-TMS v25.03, this vulnerability poses a moderate risk primarily to users who access the affected login page. Successful exploitation could allow attackers to steal session cookies or credentials, potentially leading to unauthorized access to transportation management data, disruption of logistics operations, or further lateral movement within the organization. While the vulnerability does not directly impact system availability or integrity, the confidentiality breach could expose sensitive shipment or client data. Given the critical role of transportation management systems in supply chain operations, any compromise could have cascading effects on business continuity and regulatory compliance, especially under GDPR where data breaches must be reported. The requirement for user interaction limits mass exploitation but targeted phishing campaigns could be effective. The absence of known exploits suggests limited current threat activity, but the medium severity score warrants proactive mitigation.

European organizations should implement the following specific mitigations: 1) Immediately review and restrict access to the '/clt/LOGINFRM_FCC.ASP' endpoint, applying web application firewall (WAF) rules to detect and block malicious payloads in the specified parameters. 2) Educate users on phishing risks and encourage verification of URLs before clicking, especially in emails or messages referencing the e-TMS login. 3) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers accessing the application. 4) Monitor web server logs for unusual query parameters or repeated suspicious requests targeting the vulnerable parameters. 5) Coordinate with AndSoft for timely patch deployment once available, and consider temporary mitigation such as input validation or output encoding at the application layer if source code access is possible. 6) Enforce multi-factor authentication (MFA) on e-TMS accounts to reduce risk from credential theft. 7) Conduct regular security assessments and penetration testing focused on web input validation controls.
