Stored XSS via unneutralized web_ico value
Published Apr 14, 2023 · Updated Aug 2, 2024
Stored XSS in EyouCMS 1.6.0 through 1.6.2 allows remote authenticated users to execute scripts through a crafted web_ico value. The administrative System web handler stores the web_ico form value without neutralizing active HTML, and the payload runs when the icon is reopened. Administrative privileges and later interaction with the stored icon are required; the demonstrated effect is script execution in that browser.
