CVE-2020-8087
SMC Networks D3G0804W D3GNV5M-3.5.1.6.10_GA devices allow remote command execution by leveraging access to the Network Diagnostic Tools screen, as demonstrated by an admin login.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
SMC Networks D3G0804W D3GNV5M-3.5.1.6.10_GA devices allow remote command execution by leveraging access to the Network Diagnostic Tools screen, as demonstrated by an admin login. The attacker must use a Parameter Pollution approach against goform/formSetDiagnosticToolsFmPing by providing the vlu_diagnostic_tools__ping_address parameter twice: once with a shell metacharacter and a command name, and once with a command argument.
