MediumCVSS 6.1Exploitation Probability (EPSS)
Low risk5th percentile - higher than 5% of all known CVEs
Summary
SVXportal version 2.5 and prior contain a reflected cross-site scripting vulnerability in admin/log.php via the search query parameter. When an authenticated administrator views a crafted URL, the application embeds the unsanitized parameter value directly into an HTML input value attribute, allowing attacker-supplied JavaScript to execute in the administrator's browser.
Risk Assessment
The risk for the organization includes session theft, administrative action forgery, and other browser-based attacks in the context of an admin user, potentially leading to full system compromise.
Recommendation
Immediately update SVXportal to a version later than 2.5 that includes the fix. Until then, restrict access to the admin panel and implement server-side filtering of the search parameter.
