From some limited testing, it appears that this exploit is
missing \x0d\x0a in the bad chars. If the generated payload / hunter
or egg contain that combination, it seems to cause reliability issues
and exploitation fails.

The hp_sys_mgmt_exec module for Linux is a port of the Windows module with minor changes due to the requirement of quotes. It also uses Perl instead of PHP as PHP may not always be in the environment PATH. Although the Windows module works perfectly, it now uses the same technique to encode the command (thankfully, PHP adopted major syntax characteristics and functions from Perl).
There was a disaster of a merge at 6f37cf22eb that is particularly
difficult to untangle (it was a bad merge from a long-running local
branch).
What this commit does is simulate a hard reset, by doing thing:
git checkout -b reset-hard-ohmu
git reset --hard 593363c5f9
git checkout upstream-master
git checkout -b revert-via-diff
git diff --no-prefix upstream-master..reset-hard-ohmy > patch
patch -p0 < patch
Since there was one binary change, also did this:
git checkout upstream-master data/exploits/CVE-2012-1535/Main.swf
Now we have one commit that puts everything back. It screws up
file-level history a little, but it's at least at a point where we can
move on with our lives. Sorry.
By using `php.exe` as stager, the bad characters can be completely
bypassed. This allows the use of the CmdStagerVBS, which should be
working on all supported Windows systems.
