Descriptions

It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it.

Se ha encontrado que la función sysdb_search_user_by_upn_res() de sssd en versiones anteriores a la 1.16.0 no saneaba las peticiones al consultar su caché local y era vulnerable a inyecciones. En un entorno de inicio de sesión centralizado, si un hash de contraseña se almacenaba en la caché local de un usuario determinado, un atacante autenticado podía utilizar este error para recuperarlo.
