Descriptions

Time of Check - Time of Use (TOCTOU) vulnerability in Quick Heal Total Security prior to 12.1.1.27 allows a local attacker to achieve privilege escalation, potentially leading to deletion of system files. This is achieved through exploiting the time between detecting a file as malicious and when the action of quarantining or cleaning is performed, and using the time to replace the malicious file by a symlink.

La vulnerabilidad Tiempo de comprobación - Tiempo de uso (TOCTOU) en Quick Heal Total Security anterior a la versión 12.1.1.27 permite a un atacante local conseguir una escalada de privilegios, que puede llevar a la eliminación de archivos del sistema. Esto se consigue aprovechando el tiempo que transcurre entre la detección de un archivo como malicioso y el momento en que se realiza la acción de ponerlo en cuarentena o limpiarlo, y utilizando ese tiempo para sustituir el archivo malicioso por un enlace simbólico
