mdsecactivebreach / cve-2018-4878 Goto Github PK

Greetings. I have tried this PoC with no success. The code has been tried on Windows 7 32-bit and Flash versions 26.0.0.151, 27.0.0.130, 27.0.0.170, 27.0.0.183 and 27.0.0.159 have been tried. After several attempts, the only thing that occurs is a tab crash. This is as far as the program goes:
MDSec CVE-2018-4878 POC, by Adam Chester

Corrupted object found, stopping timer
Attempting to allocate ByteArray in place of DRMOperationCompleteListener
Updating Object reference to point to m_buffer of ByteArray
Pwning ByteArray via m_buffer
XOR security key is 31338

ByteArray now has a length of: 512

Testing exploit by dumping some arbitrary memory:
Nothing happens beyond this point.
The arbitrary memory dump does not occur as expected. Any guidance or direction is greatly appreciated.

On the blog, you mention how you would later post about how to run scripts after this exploit. Do you have any tips on how someone could do that?
