CVE Publication: https://www.cve.org/CVERecord?id=CVE-2025-9145
Summary
A Stored Cross-Site Scripting (XSS) via SVG File Upload Bypass vulnerability was identified in the view_edit.shtm
endpoint of the Scada-LTS application. This vulnerability allows attackers to upload malicious files into the backgroundImageMP
parameter. The injected files are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk.
Details
