Name of the Vulnerable Software and Affected Versions Aviatrix VPN Client versions prior to 2.14.14

Description The issue is related to an unquoted search path in the Aviatrix VPN Client, which can enable local privilege escalation to the SYSTEM user. This occurs if the machine is misconfigured, allowing unprivileged users to write to directories that are supposed to be restricted to administrators.

Recommendations For versions prior to 2.14.14, update to version 2.14.14 or later to resolve the issue. As a temporary workaround, consider restricting write access to directories that are supposed to be restricted to administrators to minimize the risk of exploitation.
