Multiple Cross-Site Scripting (XSS) issues were discovered in EPESI 1.8.1.1. The vulnerabilities exist due to insufficient filtration of user-supplied data (state, element, id, tab, cid) passed to the “EPESI-master/modules/Utils/RecordBrowser/favorites.php” URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.
