CVE-2020-5895: F5 Nginx Controller

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

On NGINX Controller versions 3.1.0-3.3.0, AVRD uses world-readable and world-writable permissions on its socket, which allows processes or users on the local system to write arbitrary data into the socket. A local system attacker can make AVRD segmentation fault (SIGSEGV) by writing malformed messages to the socket.

Affected products

• F5 Nginx Controller: from 3.1.0, before 3.4.0 (fixed in 3.4.0)
