Re: XXE Injection in HP Release Control

Hello MustLive,

Did you disclose this to HP? You didn't mention whether this is 0-day or
disclosed (I think you usually publish your disclosure timeline)

Thanks
Doug

Hello!

I'll give you additional information concerning advisory HP Release Control
Authenticated XXE Exploit (http://1337day.com/exploit/description/22267).
Three different vulnerabilities were used in this exploit for successful
attack. For my attack it's needed to use only one vulnerability (exactly the
XXE) to conduct attacks on other web sites from target host.

-------------------------
Affected products:
-------------------------

HP Release Control 9.20.0000 Build 395 and previous versions.

-------------------------
Affected vendors:
-------------------------

Hewlett-Packard.

HP Release Control is vulnerable to XXE Injection.

Besides standard vectors of attacks with XXE Injection vulnerabilities (such
as local file inclusion), which are usually mentioned in advisories, XXE
Injection also allows to conduct attacks on other sites. And with using
DAVOSET (DDoS attacks via other sites execution tool) it's possible to
automate such attacks.

I wrote about such attacks in my 2012's article "Using XML External Entities
(XXE) for attacks on other sites"
(
http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2012-August/008481.html
)
and 2013's "Using XXE vulnerabilities for attacks on other sites"
(
http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2013-August/008887.html
).
As I described in my articles, XXE vulnerabilities can be used for
conducting CSRF and DoS attacks on other sites (and at using multiple web
sites it's possible to conduct DDoS attacks). And my tool DAVOSET can be
used for conducting such attacks via XXE vulnerabilities.

Video demonstration of DAVOSET: http://www.youtube.com/watch?v=RKi35-f346I

So all vulnerable versions of HP Release Control can be used for attacks on
other sites via XXE Injection.
