CVE-2023-43345Public exploit

Client-side script execution via unsanitized page name

Published Oct 19, 2023 · Updated Sep 12, 2024

Stored XSS in OpenSolution Quick CMS 6.7 allows local users to execute JavaScript through a crafted Pages Menu Content Name. The Pages Menu editor stores the Content Name without neutralizing an injected SVG onload handler, which executes when the resulting page is viewed. Access to the administration panel and permission to edit page content are required; exploitation runs script in a visitor's browser context.
