pathC:\program files\SolarWinds\DameWare Mini Remote Control 10.0 x64 #1\DWRCC.exe↗
commandDWRCC.exe -c: -h: -m:<300*A>↗
  • →Monitor execution of DWRCC.exe with a -m: argument containing an anomalously long string (300+ characters) as the machine name parameter, which is the overflow vector. ↗
  • →The PoC constructs a 300-byte buffer of repeated 'A' characters passed to the -m: (machine host name) parameter; detect command-line invocations of DWRCC.exe where -m: is followed by an unusually large value. ↗
  • →The exploit is delivered via VBScript (WScript.Shell / CreateObject) launching DWRCC.exe; monitor for scripting engines (wscript.exe/cscript.exe) spawning DWRCC.exe as a child process. ↗
  • ·Vulnerability is specific to the x64 build of DameWare Mini Remote Control version 10.0; other versions or architectures are not confirmed affected. ↗
  • ·The PoC was tested only on Windows 7 SP1 x64; exploit reliability on other Windows versions is unconfirmed. ↗
  • ·The overflow is triggered via the command-line -m: (machine name) parameter, not over the network; exploitation requires local or scripted execution of DWRCC.exe. ↗
