CVE-2025-59746 is a reflected Cross-Site Scripting (XSS) vulnerability identified in AndSoft's e-TMS product, specifically version 25.03. The vulnerability arises due to improper neutralization of input during web page generation, classified under CWE-79. The issue is located in the handling of the 'm' parameter within the '/lib/asp/alert.asp' endpoint. An attacker can craft a malicious URL containing JavaScript code embedded in the 'm' parameter, which, when accessed by a victim, causes the victim's browser to execute the injected script. This reflected XSS does not require authentication, user interaction beyond clicking the malicious link, or elevated privileges, making it relatively easy to exploit remotely. The CVSS v4.0 base score is 6.9 (medium severity), reflecting network attack vector, low complexity, no privileges or user interaction required, and limited impact confined to confidentiality. The vulnerability does not affect integrity or availability directly but can be leveraged for session hijacking, phishing, or delivering further payloads. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on October 2, 2025, with INCIBE as the assigner. Given the nature of reflected XSS, the attack surface includes any user of the vulnerable e-TMS web interface who can be tricked into clicking a malicious link. The lack of input sanitization or output encoding in the 'm' parameter processing is the root cause, which should be addressed by proper input validation and context-aware output encoding in the web application code.

For European organizations using AndSoft e-TMS v25.03, this vulnerability poses a moderate risk primarily to confidentiality and user trust. Attackers could exploit the XSS flaw to steal session cookies, enabling unauthorized access to user sessions, or conduct phishing attacks by injecting deceptive content into the application interface. This can lead to credential theft, unauthorized data access, or lateral movement within the organization’s network if the e-TMS system integrates with other internal services. While the vulnerability does not directly compromise system integrity or availability, the indirect consequences such as data leakage, reputational damage, and compliance violations (e.g., GDPR) can be significant. Organizations in sectors relying on e-TMS for transportation management, logistics, or supply chain operations may face operational disruptions if users fall victim to these attacks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers often weaponize such vulnerabilities rapidly after disclosure.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Immediately apply any available patches or updates from AndSoft once released. 2) If patches are not yet available, deploy web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'm' parameter in '/lib/asp/alert.asp'. 3) Conduct input validation and output encoding on all user-supplied data, particularly the 'm' parameter, ensuring special characters are properly escaped in the HTML context. 4) Educate users about the risks of clicking unsolicited links and implement email filtering to reduce phishing attempts. 5) Monitor web server logs for unusual query strings or repeated attempts to exploit the 'm' parameter. 6) Consider implementing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. 7) Review session management practices to ensure cookies are marked HttpOnly and Secure to reduce the impact of session theft. 8) Engage in regular security assessments and penetration testing focused on web application vulnerabilities to detect similar issues proactively.
