* [*] Mozilla Firefox 3.6.8 Adobe Reader Plugin 9.3.4.218 DLL Hijacking Exploit (CoolType.dll)
* [*]
* [*] Author: Rh0 (Rh0[at].z1p.biz)
* [*] Affected Software: Mozilla Firefox 3.6.8 with Adobe Reader Plugin 9.3.4.218
* [*] Tested on: Windows XP Pro SP3 x86 En
* [*] Description:
*
* Affected Extensions: .pdf .pdfxml .mars .fdf .xfdf .xdp .xfd
*
* When Firefox plugins are used, the necessary DLLs for the plugin to run
* are searched in folders in the following order:
*
* mozilla firefox dir
* windows system32 dir
* windows system dir
* windows dir
* current dir <-- hijack possibility
* plugin program dir
*
* Hence, depending on the actual file, the plugin and the needed DLLs, plugin DLLs can be hijacked.
* just 2 examples for the Adobe Reader plugin:
* CoolType.dll
* authplay.dll (if the pdf contains an embedded swf file)
*
* This Batch File example creates an mininal pdf file, CoolType.c and
* compiles it to CoolType.dll (gcc has to be installed).
* When opening the pdf with Firefox, CoolType.dll gets executed, if both files are in the same directory.
* So embedded pdf files in a html file could be used to hijack Adobe Reader DLLs.
* For this exploit to work, Firefox and the Adober Reader 9.3.4 plugin have to be installed.
* To test the other extensions simply change the extension of the pdf file, and open it with firefox
