Hardcore Disassembler / Reverse Engineer

Reversing must be a passion as your skills will be challenged
on a daily basis and you will be working several hours
everyday in IDA, Ollydbg, and with BinDiff. Often, it is also
required that you write a PoC or even a working exploit to
prove that an issue is exploitable.

DESCRIPTION:
A vulnerability has been reported in Trac, which can be exploited by
malicious users to conduct script insertion attacks and disclose
sensitive information.

The vulnerability is caused due to an error in the handling of the
"include" and "raw" reStructuredText directives. This can be
exploited to disclose the content of arbitrary files from local and
external resources, or inject arbitrary HTML and script code, which
will be executed in a user's browser session in context of an
affected site when the malicious user data is viewed.

Successful exploitation requires that the docutils package is
installed and enabled, and that the user has permissions to submit
wiki pages and tickets.

The vulnerability has been reported in versions prior to 0.9.6.
