Is this file on the android device or on the PC?


xsl:variable name=Command![CDATA[calc.exe]]/xsl:variable

This causes calc.exe to be run on the PC, right?

Advisory Details:

Newtelligence dasBlog ct.ashx is vulnerable to Open Redirect attacks.


dasBlog supports a feature called Click-Through which basically tracks all
links clicked inside your blog posts. It's a nice feature that allows the
blogger to stay informed what kind of content readers like. If
Click-Through is turned on, all URLs inside blog entries will be replaced
with URL to your blog/ct.ashx?id=Blog entry IDurl=URL-encoded
original URL which of course breaks WebSnapr previews.


Web.config code:
add verb=* path=ct.ashx
type=newtelligence.DasBlog.Web.Services.ClickThroughHandler,
newtelligence.DasBlog.Web.Services/


(1) The vulnerability occurs at ct.ashx? page, with url parameter.



Solutions:
2014-10-15 Public disclosure with self-written patch.

[FD] Mozilla mozilla.org Two Sub-Domains ( Cross Reference) XSS Vulnerability ( All URLs Under the Two Domains)

[Jing Wang]

Domains:
http://lxr.mozilla.org/
http://mxr.mozilla.org/
(The two domains above are almost the same)




Websites information:
lxr.mozilla.org, mxr.mozilla.org are cross references designed to display
the Mozilla source code. The sources displayed are those that are currently
checked in to the mainline of the mozilla.org CVS server, Mercurial Server,
and Subversion Server; these pages are updated many times a day, so they
should be pretty close to the latest‑and‑greatest. (from Mozilla)




Vulnerability description:
All pages under the following two URLs are vulnerable.
http://lxr.mozilla.org/mozilla-central/source
http://mxr.mozilla.org/mozilla-central/source


This means all URLs under the above two domains can be used for XSS attacks
targeting Mozilla's users.

Since there are large number of pages under them. Meanwhile, the contents
of the two domains vary. This makes the vulnerability very dangerous.
Attackers can use different URLs to design XSS attacks to Mozilla's variety
class of users.

The vulnerability have been reported to bugzilla.mozilla.org. Mozilla are
dealing with this issue.




POCs:
http://lxr.mozilla.org/mozilla-central/source/body
onload=prompt(justqdjing)
http://lxr.mozilla.org/mozilla-central/source/mobile/android/body
onload=prompt(justqdjing)

onload=prompt(tetraph)




POC Video:

Vulnerability Analysis:
Take the following link as an example,
http://lxr.mozilla.org/mozilla-central/source/chrome/attacktest

We can see that for the page reflected, it contains the following codes.
a href=/mozilla-central/source/chrome/%253Cattacktest%253E
attacktest/attacktest
/a

If we insert body onload=prompt(justqdjing) into the URL, the code
can be executed.




The vulnerability can be attacked without user login. My tests were
performed on Firefox (26.0) in Ubuntu (12.04) and IE (9.0.15) in Windows 7.


Cross-site scripting (XSS) is a type of computer security vulnerability
typically found in Web applications. XSS enables attackers to inject
client-side script into Web pages viewed by other users. A cross-site
scripting vulnerability may be used by attackers to bypass access controls
such as the same origin policy. (From Wikipedia)
