Descriptions

Auth. (admin+) Stored Cross-Site Scripting (XSS) vulnerability in Alexander Semikashev Yandex Metrica Counter plugin <= 1.4.3 versions.

Vulnerabilidad de Cross-Site Scripting (XSS) Almacenado en el plugin Yandex Metrica Counter de Alexander Semikashev que afecta a versiones 1.4.3 e inferiores. Para explotar esta vulnerabilidad hace falta estar autenticado y tener permisos de administrador o superior.

The Yandex Metrica Counter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via plugin settings in versions up to, and including, 1.4.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only impacts multi-site installations and installations where unfiltered_html has been disabled.
