Can you explain this vulnerability to me?
CVE-2025-57881 is a reflected cross-site scripting (XSS) vulnerability in the modifyEmail functionality of MedDream PACS Premium 7.3.6.870. It occurs because the 'server' parameter in the modifyEmail.php script is not properly sanitized before being included in an error message on the HTML page. An attacker can craft a malicious URL with a script in the 'server' parameter, which will then be reflected back and executed in the victim's browser if they visit the URL. This requires the attacker to be authenticated and involves user interaction. [1]
How can this vulnerability impact me? :
This vulnerability can allow an attacker to execute arbitrary JavaScript code in the context of the victim's browser session. This can lead to theft of sensitive information, session hijacking, or performing actions on behalf of the user. Since it affects a medical image management system, it could potentially expose sensitive medical data or disrupt user trust. However, the impact is rated as low to moderate with a CVSS score of 6.1, indicating limited confidentiality and integrity impact and no availability impact. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by attempting to access the modifyEmail functionality with a crafted URL that includes a script tag in the 'server' parameter, such as: GET /Pacs/modifyEmail.php?server=<script>alert(1)</script>. If the response HTML contains the injected script inside an error message, the system is vulnerable. You can use tools like curl or wget to send this request and inspect the response. For example, using curl: curl -i 'http://<target>/Pacs/modifyEmail.php?server=<script>alert(1)</script>' and check if the response contains the script tag reflected in the HTML error message. [1]
What immediate steps should I take to mitigate this vulnerability?
The immediate step to mitigate this vulnerability is to apply the vendor's patch released on December 5, 2025, which addresses the improper sanitization of the 'server' parameter in the modifyEmail functionality. Until the patch is applied, restrict access to the affected functionality to trusted users only, and consider implementing web application firewall (WAF) rules to detect and block requests containing suspicious script tags in the 'server' parameter.
