Executive Summary

CVE-2025-54852 is a reflected cross-site scripting (XSS) vulnerability in the modifyAeTitle functionality of MedDream PACS Premium 7.3.6.870. The vulnerability occurs because the 'title' parameter from a URL query string is directly embedded into the HTML output without proper sanitization. If the 'title' parameter does not match an entry in the database, the application outputs an error message containing the unsanitized 'title' value. An attacker can craft a malicious URL containing JavaScript code in the 'title' parameter, which will then be executed in the victim's browser when they visit the URL. This can happen without any user authentication. [1]

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary JavaScript code in the context of a victim's browser when they visit a specially crafted URL. This can lead to theft of session cookies, user impersonation, or other malicious actions performed on behalf of the victim. Since the vulnerability is pre-authentication and exploitable over the network, it can be triggered by simply convincing a user to click a malicious link, potentially compromising user data and system integrity.

Detection Guidance

This vulnerability can be detected by sending crafted HTTP GET requests to the vulnerable endpoint and observing if the response reflects unsanitized input in the HTML output. For example, you can use curl or similar tools to send a request like: curl -i "http://<target>/Pacs/modifyAeTitle.php?title=<script>alert(1)</script>" and check if the response contains the injected script tag. If the script tag appears in the response HTML without sanitization, the system is vulnerable. [1]

Mitigation Strategies

Immediate mitigation steps include applying the vendor's patch released on December 5, 2025, which fixes the vulnerability by properly sanitizing the 'title' parameter. Until the patch can be applied, you can implement web application firewall (WAF) rules to block requests containing suspicious script tags or other potentially malicious input in the 'title' parameter. Additionally, restricting access to the modifyAeTitle.php endpoint to trusted users or networks can reduce exposure. [1]
