CVE-2022-0719Network attack vector

Browser script execution via incorrect URL sanitization

Published Feb 23, 2022 · Updated Aug 2, 2024

Reflected XSS in Microweber before 1.3 allows remote authenticated users to execute script in another user's browser through a crafted URL. UrlManager::string sanitizes request parameters with HTMLClean::cleanArray, while the fix replaces that call with HTMLClean::clean before returning the URL string. A logged-in attacker must persuade another user to open the crafted URL; script execution is confined to that user's Microweber browser context.
