CVE-2025-59748: AndSoft E-tms XSS Vulnerability

CVE-2025-59748 Overview

CVE-2025-59748 is a reflected cross-site scripting (XSS) vulnerability in AndSoft's e-TMS transport management platform, version 25.03. The flaw resides in the /clt/changepassword.asp endpoint, where the l and reset parameters are echoed into the HTTP response without proper output encoding. An attacker can craft a malicious URL that executes arbitrary JavaScript in the victim's browser when clicked. The issue is tracked under CWE-79 and was disclosed through Spain's national CERT, INCIBE.

Critical Impact
Successful exploitation allows attackers to run arbitrary JavaScript in an authenticated user's browser session, enabling session token theft, credential harvesting through fake login prompts, and unauthorized actions against the e-TMS application.

Technical Details for CVE-2025-59748

Vulnerability Analysis

The vulnerability is a reflected XSS flaw in the password reset workflow of e-TMS. The changepassword.asp script consumes the l and reset query-string parameters and includes their values in the rendered HTML response. Because the application does not sanitize or context-encode this input, an attacker can inject HTML and JavaScript that the browser executes within the origin of the e-TMS deployment.

Exploitation follows the classic reflected-XSS pattern. The attacker delivers a crafted link to a target through email, chat, or a compromised web page. When the victim, typically an authenticated e-TMS user, opens the URL, the injected script runs in the security context of the e-TMS host. Because e-TMS is a transport management system handling logistics, shipment, and customer data, a compromised session can expose sensitive operational information.

Root Cause

The root cause is missing output encoding of user-supplied input reflected into an HTML response, classified under CWE-79: Improper Neutralization of Input During Web Page Generation. The l and reset parameters are trusted and written back to the page verbatim, allowing angle brackets, script tags, and event handlers to break out of the intended data context.

Attack Vector

The vulnerability is network-exploitable, requires no privileges, and requires user interaction limited to clicking a crafted URL. A typical attack chain sends the victim to a URL such as /clt/changepassword.asp?l=<payload>&reset=<payload>, where the injected payload contains JavaScript that steals cookies, submits requests on behalf of the user, or renders a phishing overlay. See the INCIBE Security Notice Update for coordinated advisory details.

Detection Methods for CVE-2025-59748

Indicators of Compromise

HTTP requests to /clt/changepassword.asp containing l= or reset= values with encoded angle brackets, script, onerror, onload, or javascript: substrings.
Referrer headers pointing to external domains preceding password-reset requests from internal users.
Anomalous outbound requests from client browsers to attacker-controlled domains shortly after visiting the e-TMS reset page.

Detection Strategies

Deploy web application firewall (WAF) signatures that inspect l and reset query parameters for HTML and JavaScript metacharacters.
Review IIS or reverse-proxy access logs for URL-encoded XSS payloads (%3Cscript, %3Cimg, %22onerror%3D) targeting the changepassword.asp path.
Correlate suspicious URL clicks in email security telemetry with subsequent user sessions on the e-TMS application.

Monitoring Recommendations

Enable full request logging on the e-TMS front-end web server, including query strings, and forward to a centralized SIEM for retention and search.
Alert on any 200-OK response from /clt/changepassword.asp where the request URI length exceeds a defined baseline, which typically indicates payload injection attempts.
Monitor Content Security Policy (CSP) violation reports if a policy is configured, since injected inline scripts will trigger reports.

How to Mitigate CVE-2025-59748

Immediate Actions Required

Contact AndSoft to obtain the fixed release addressing the changepassword.asp reflection issue and schedule an upgrade window.
Restrict access to the e-TMS web interface to trusted networks or via VPN until patched, reducing exposure to internet-based phishing lures.
Educate users, especially administrators and dispatchers, to avoid clicking password-reset links received from untrusted sources.

Patch Information

No vendor patch URL is listed in the NVD record at time of writing. Refer to the INCIBE Security Notice Update for the coordinated advisory covering multiple vulnerabilities in AndSoft e-TMS, and follow AndSoft's customer support channels for the latest fixed build beyond version 25.03.

Workarounds

Configure a WAF rule to block or strip HTML metacharacters (<, >, ", ') in the l and reset parameters of /clt/changepassword.asp.
Deploy a strict Content Security Policy on the e-TMS host that disallows inline scripts and restricts script sources to trusted origins.
Set the HttpOnly and Secure flags on session cookies to reduce the impact of a successful XSS payload attempting to exfiltrate the session identifier.
