CVE-2022-23650 : What You Need to Know

Netmaker is a platform for creating and managing virtual overlay networks using WireGuard. Prior to versions 0.8.5, 0.9.4 and 0.10.0, a hard-coded cryptographic key in the code base allows exploitation to run admin commands on a remote server if the exploiter knows the address and username of the admin. This affects the server component (Netmaker) but not clients. The issue has been addressed in Netmaker v0.8.5, v0.9.4, and v0.10.0, with no known workarounds.
