  # Exploit Title: MiniWeb HTTP Server 0.8.19 - Buffer Overflow (PoC) # Date: 13.12.2020 # Exploit Author: securityforeveryone.com # Author Mail: hello[AT]securityforeveryone.com # Vendor Homepage: https://sourceforge.net/projects/miniweb/ # Software Link: https://sourceforge.net/projects/miniweb/files/miniweb/0.8/miniweb-win32-20130309.zip/download # Version: 0.8.19 # Tested on: Win7 x86 # Researchers: Security For Everyone Team - https://securityforeveryone.com   ''' Description   MiniWeb HTTP server 0.8.19 allows remote attackers to cause a denial of service (daemon crash) via a long name for the first parameter in a POST request.   Exploitation   The vulnerability is the first parameter's name of the POST request. Example: PARAM_NAME1=param_data1&param_name2=param_data2 if we send a lot of "A" characters to "PARAM_NAME1", the miniweb server will crash.   About Security For Everyone Team   We are a team that has been working on cyber security in the industry for a long time.
