DescriptionCVE.org

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.

Analysis

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.

A successful exploit could allow the attacker to delete arbitrary files from the file system of the affected device.

Technical ContextAI

Path traversal allows an attacker to access files outside the intended directory by manipulating file paths with sequences like '../'.

RemediationAI

Validate and sanitize file path inputs. Use a whitelist of allowed files or directories. Implement chroot jails or containerization.
