CVE-2023-2477Public exploitNetwork attack vector

Cross-site scripting via unsanitized file argument

Published May 2, 2023 · Updated Aug 2, 2024

Cross-site scripting in Cx.php in FunAdmin 3.2.0 through 3.2.3 allows remote authenticated users to inject browser script. The tagLoad function places the attacker-controlled file argument into generated page content without neutralizing markup. A logged-in user must supply the payload and another user must render the affected content, enabling script execution in that user's browser context.
