Submit #917693: D-Link Router D-Link DWR-M921 V1.1.52 Command Injectioninfo

TitleD-Link Router D-Link DWR-M921 V1.1.52 Command Injection
DescriptionA vulnerability has been found in D-Link DWR-M921 firmware V1.1.52. It can be triggered through the route /boafrm/formDebugDiagnosticRun. The manipulation of the argument host leads to OS command injection. The attack is possible remotely after authentication. The internal diagnostic handler sub_419898 filters ;, | and & from the host parameter, but misses $() and backticks, so $(CMD) bypasses the filter and injects arbitrary commands.
