CVE-2021-36705
In ProLink PRC2402M V1.0.18 and older, the set_TR069 function in the adm.cgi binary, accessible with a page parameter value of TR069 contains a trivial command injection where the value of the TR069_local_port parameter is passed directly to system.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.62%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
