CVE-2022-4377Network attack vector

Script execution via unneutralized Make a Call input

Published Dec 9, 2022 · Updated Apr 15, 2025

Cross-site scripting in S-CMS 5.0 Build 20220328 allows remote authenticated users to inject script through the Make a Call field. The Contact Information Page renders the field's unneutralized value as web content, causing a viewer's browser to execute attacker-supplied script. Low-privileged access and a separate user's interaction are required, and successful exploitation runs script in that viewer's browser.
