Last modified
CVE-2021-20145 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Gryphon Tower routers contain an unprotected openvpn configuration file which can grant attackers access to the Gryphon homebound VPN network which exposes the LAN interfaces of other users' devices connected to the same service.

EPSS estimates a 1.24% chance of exploitation in the next 30 days.
