CVE-2024-1775
The Nextend Social Login and Register plugin for WordPress is vulnerable to a self-based Reflected Cross-Site Scripting via the ‘error_description’ parameter in all versions up to, and including, 3.1.12 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers, with access to a subscriber-level account, to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

NOTE: This vulnerability can be successfully exploited on a vulnerable WordPress instance against an OAuth pre-authenticated higher-level user (e.g., administrator) by leveraging a cross-site request forgery in conjunction with a certain social engineering technique to achieve a critical impact scenario (cross-site scripting to administrator-level account creation). However, successful exploitation requires "Debug mode" to be enabled in the plugin's "Global Settings".

"value": "El complemento de inicio de sesión y registro social de Nextend para WordPress es vulnerable a Cross-Site Scripting Reflejado a través del parámetro 'error_description' en todas las versiones hasta la 3.1.12 incluida debido a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes no autenticados, con acceso a una cuenta de nivel de suscriptor, inyecten scripts web arbitrarios en páginas que se ejecutan si pueden engañar con éxito a un usuario para que realice una acción como hacer clic en un enlace. NOTA: Esta vulnerabilidad se puede explotar con éxito en una instancia vulnerable de WordPress contra un usuario de nivel superior autenticado previamente con OAuth (por ejemplo, administrador) aprovechando Cross-Site Scripting junto con una determinada técnica de ingeniería social para lograr un escenario de impacto crítico. (Cross-Site Scripting para la creación de cuentas a nivel de administrador). Sin embargo, una explotación exitosa requiere que el \"modo de depuración\" esté habilitado en la \"Configuración global\" del complemento."
