Descriptions

A vulnerability in the endpoint software of Cisco AMP for Endpoints and Clam AntiVirus could allow an authenticated, local attacker to cause the running software to delete arbitrary files on the system. The vulnerability is due to a race condition that could occur when scanning malicious files. An attacker with local shell access could exploit this vulnerability by executing a script that could trigger the race condition. A successful exploit could allow the attacker to delete arbitrary files on the system that the attacker would not normally have privileges to delete, producing system instability or causing the endpoint software to stop working.

Una vulnerabilidad en el software de endpoint de Cisco AMP para Endpoints y Clam AntiVirus, podría permitir a un atacante local autenticado causar que el software en ejecución elimine archivos arbitrarios en el sistema. La vulnerabilidad es debido a una condición de carrera que podría ocurrir cuando se escanean archivos maliciosos. Un atacante con acceso de shell local podría explotar esta vulnerabilidad al ejecutar un script que podría desencadenar una condición de carrera. Una explotación con éxito podría permitir al atacante eliminar archivos arbitrarios en el sistema que el atacante normalmente no tendría privilegios para eliminar, produciendo inestabilidad del sistema o causando que el software de endpoint deje de funcionar
