Descriptions

CISOfy Lynis before 3.0.0 has Incorrect Access Control because of a TOCTOU race condition. The routine to check the log and report file permissions was not working as intended and could be bypassed locally. Because of the race, an unprivileged attacker can set up a log and report file, and control that up to the point where the specific routine is doing its check. After that, the file can be removed, recreated, and used for additional attacks.

CISOfy Lynis versiones anteriores a 3.0.0, presenta un Control de Acceso Incorrecto debido a una condición de carrera TOCTOU. La rutina para comprobar los permisos del archivo de registro e informe no funcionaba según lo previsto y podía ser omitida localmente. Debido a la carrera, un atacante no privilegiado puede configurar un archivo de registro e informe, y controlarlo hasta el punto en que la rutina específica esté haciendo su comprobación. Después de eso, el archivo puede ser eliminado, creado nuevamente y usado para ataques adicionales
