CVE-2025-59774 is a reflected Cross-site Scripting (XSS) vulnerability identified in AndSoft's e-TMS version 25.03. The vulnerability arises from improper neutralization of input during web page generation, specifically involving the parameters 'l', 'demo', 'demo2', 'TNTLOGIN', 'UO', and 'SuppConn' in the '/clt/LOGINFRM_VON.ASP' endpoint. An attacker can craft a malicious URL containing JavaScript code embedded within these parameters. When a victim accesses this URL, the injected script executes in their browser context. This can lead 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 no privileges, but does require user interaction (UI:A) as the victim must click or visit the malicious link. The CVSS 4.0 base score is 5.1 (medium severity), reflecting limited confidentiality impact (VC:L), no integrity or availability impact, and low scope impact (SI:L). There are no known exploits in the wild as of the published date, and no patches have been released yet. The vulnerability is assigned CWE-79, which is a common and well-understood web application security issue related to insufficient input validation and output encoding.

For European organizations using AndSoft e-TMS v25.03, this vulnerability poses a moderate risk primarily to end users who access the affected login page. Successful exploitation could lead to theft of session cookies or credentials, enabling attackers to impersonate legitimate users and potentially access sensitive transportation management data. This could disrupt logistics operations, cause data breaches, or facilitate further attacks within the network. The impact on confidentiality is limited but non-negligible, especially if the compromised accounts have elevated privileges. Integrity and availability impacts are minimal. However, given the critical role of transportation management systems in supply chains, even moderate disruptions or data leaks could have cascading effects on business continuity and compliance with data protection regulations such as GDPR. The requirement for user interaction reduces the likelihood of widespread automated exploitation but targeted phishing campaigns could be effective.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Apply strict input validation and output encoding on all user-supplied parameters, especially those identified ('l', 'demo', 'demo2', 'TNTLOGIN', 'UO', 'SuppConn') in the '/clt/LOGINFRM_VON.ASP' endpoint. Use context-aware encoding (e.g., HTML entity encoding) to neutralize scripts. 2) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. 3) Educate users to recognize and avoid clicking suspicious links, particularly those received via email or messaging. 4) Monitor web server logs for unusual parameter values or repeated attempts to inject scripts. 5) Coordinate with AndSoft to obtain patches or updates as soon as they become available and prioritize their deployment. 6) Consider implementing web application firewalls (WAF) with rules to detect and block reflected XSS payloads targeting these parameters. 7) Conduct security testing and code reviews focused on input handling in the affected application components.
