CVE-2019-20488
Multiple actions within the web management interface (setup.cgi) are vulnerable to command injection, allowing remote attackers to execute arbitrary commands, as demonstrated by shell metacharacters in the sysDNSHost parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.12%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
