CVE-2018-7749
The SSH server implementation of AsyncSSH before 1.12.1 does not properly check whether authentication is completed before processing other requests.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The SSH server implementation of AsyncSSH before 1.12.1 does not properly check whether authentication is completed before processing other requests. A customized SSH client can simply skip the authentication step.
