Synology Assistant is vulnerable to an incorrect default permissions flaw that allows local attackers to gain unauthorized access or elevate privileges on the host system.

This is a CWE-276 incorrect default permissions vulnerability. The issue allows a local authenticated user, potentially in conjunction with user interaction, to impact the confidentiality, integrity, and availability of the system.

With a CVSS score of 7.3, this vulnerability poses a significant risk to local system security. Successful exploitation could allow a standard user to modify protected files or elevate their rights, leading to full system compromise or persistence for a malicious actor.

Immediate Action: Update Synology Assistant to version 7.0.7-50095 or later to correct the file and directory permission settings.

Proactive Monitoring: Monitor local system logs for unauthorized attempts to access or modify configuration files associated with the Synology Assistant installation.

Compensating Controls: Enforce strict least-privilege policies for local users on any workstation where Synology Assistant is installed to minimize the impact of potential local exploitation.

Public Exploit Available: Unknown

Synology users should apply the update to version 7.0.7-50095 as soon as possible to remediate the incorrect permissions. Addressing local privilege escalation vectors is an essential component of maintaining a secure workstation environment.
