# Title: BearShare Lite 5.2.5 - 'Advanced Search'Buffer Overflow in (PoC)
|

# Date: 2020-09-29
|

# Author: Christian Vierschilling
|
||||
# Vendor Homepage: http://www.bearshareofficial.com/
|
||||
# Software Link: http://www.oldversion.com.de/windows/bearshare-lite-5-2-5
|
||||
# Versions: 5.1.0 - 5.2.5
|

# Tested on: Windows 10 x64 EN/DE
|

# CVE: NA

|

# --- EXPLOTATION INSTRUCTIONS --- #
|
||||
# 1. Adjust the values for "jmp_esp" and "shellcode" if needed
|
||||
# 2. Run the script to generate a file pwn.txt, containing your payload
|
||||
# 3. Open pwn.txt on your target (!!) (e.g. in the browser or locally) and copy the contents into the clipboard
|
||||
# 4. Start BearShare, click on "Advanced..." and a new window will pop up. Put the payload from pwn.txt into the field "Keywords:" within the new window. Click on "Search" in this window and your payload will be executed.

# Exploit Title: CloudMe 1.11.2 - Buffer Overflow ROP (DEP,ASLR)
|

# Exploit Author: Bobby Cooke (boku)
|

# CVE: CVE-2018-6892
|
||||
# Date: 2020-09-29
|
||||
# Vendor Homepage: https://www.cloudme.com/
|
||||
# Software Link: https://www.cloudme.com/downloads/CloudMe_1112.exe
|
||||
# Version: 1.11.2
|
||||
# Tested On: Windows 10 (x64) - 10.0.19041 Build 19041
|
||||
# Script: Python 2.7
|
||||
# Notes:
|
||||
# This exploit uses MSVCRT.System to create a new user (boku:0v3R9000!) and add the new user to the
|
||||
# Administrators group. A requirement of successful exploitation is the CloudMe.exe process must be
|
||||
# running as adminstrator, such as when ran with 'Run as Administrator'; as this permission is required
|
||||
# to create new users on the system. This exploit has been tested against multiple Windows 10 systems
|
||||
# including x86, x64, Pro, Education, Home; although there is no guarantee it will work in your CTF.
