CVE-2025-59759 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_DELCROIX.ASP' endpoint. An attacker can craft a malicious URL containing executable JavaScript code embedded in these parameters. When a victim clicks this URL, the injected script executes in the victim's browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The vulnerability is exploitable remotely without authentication (AV:N/PR:N), requires low attack complexity (AC:L), but does require user interaction (UI:A) such as clicking a malicious link. The impact on confidentiality is low (VC:L), with no impact on integrity or availability. The CVSS 4.0 base score is 5.1, classifying it as a medium severity issue. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is assigned CWE-79, which is a common web application security weakness involving improper input sanitization leading to XSS.

For European organizations using AndSoft's e-TMS v25.03, this vulnerability poses a moderate risk primarily to user confidentiality and trust. Successful exploitation could allow attackers to steal session cookies or credentials, enabling unauthorized access to the transportation management system. This could disrupt logistics operations, expose sensitive shipment data, or facilitate further attacks within the network. Although the vulnerability does not directly impact system integrity or availability, the indirect consequences of compromised user accounts could be significant, especially in sectors relying heavily on secure and reliable transport management such as manufacturing, retail, and supply chain services. The requirement for user interaction limits mass exploitation but targeted phishing campaigns could be effective. The absence of known exploits reduces immediate risk but organizations should remain vigilant given the critical nature of logistics infrastructure in Europe.

European organizations should implement the following specific mitigations: 1) Immediately review and restrict the use of the vulnerable parameters ('l', 'demo', 'demo2', 'TNTLOGIN', 'UO', 'SuppConn') in the '/clt/LOGINFRM_DELCROIX.ASP' endpoint, applying strict input validation and output encoding to neutralize malicious scripts. 2) Employ Web Application Firewalls (WAFs) with updated rules to detect and block suspicious payloads targeting these parameters. 3) Conduct user awareness training focused on recognizing phishing attempts involving malicious URLs. 4) Monitor web server logs for unusual query strings or repeated access attempts to the affected endpoint. 5) Coordinate with AndSoft to obtain patches or updates as soon as they become available and plan for prompt deployment. 6) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the e-TMS application. 7) Use multi-factor authentication (MFA) to reduce the impact of credential theft resulting from XSS exploitation.
