CVE-2025-20259

Multiple vulnerabilities in the update process of Cisco ThousandEyes Endpoint Agent for Windows could allow an authenticated, local attacker to delete arbitrary files on an affected device. These vulnerabilities are due to improper access controls on files that are in the local file system. An attacker could exploit these vulnerabilities by using a symbolic link to perform an agent upgrade that redirects the delete operation of any protected file. A successful exploit could allow the attacker to delete arbitrary files from the file system of the affected device.

Summary		(es) Varias vulnerabilidades en el proceso de actualización de Cisco ThousandEyes Endpoint Agent para Windows podrían permitir que un atacante local autenticado elimine archivos arbitrarios en un dispositivo afectado. Estas vulnerabilidades se deben a controles de acceso inadecuados a los archivos del sistema de archivos local. Un atacante podría explotar estas vulnerabilidades mediante un enlace simbólico para realizar una actualización del agente que redirija la operación de eliminación de cualquier archivo protegido. Una explotación exitosa podría permitir al atacante eliminar archivos arbitrarios del sistema de archivos del dispositivo afectado.
