CVE-2020-14077
TRENDnet TEW-827DRU devices through 2.06B04 contain a stack-based buffer overflow in the ssi binary.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
TRENDnet TEW-827DRU devices through 2.06B04 contain a stack-based buffer overflow in the ssi binary. The overflow allows an authenticated user to execute arbitrary code by POSTing to apply.cgi via the action set_sta_enrollee_pin_wifi1 (or set_sta_enrollee_pin_wifi0) with a sufficiently long wps_sta_enrollee_pin key.
