TITLE:
HAURI LiveCall Arbitrary File Overwrite Vulnerability

SECUNIA ADVISORY ID:
SA16221

VERIFY ADVISORY:
http://secunia.com/advisories/16221/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
HAURI LiveCall
http://secunia.com/product/5448/

DESCRIPTION:
Neo and Park Gyu Tae have reported a vulnerability in LiveCall, which
potentially can be exploited by malicious people to compromise a
vulnerable system.

The vulnerability is caused due to the LiveCall ActiveX control
failing to verify some input parameters (e.g. the URL of the update
site) and the authenticity of the received live update configuration
file (liveup.haz). This can potentially be exploited to download
arbitrary files to a user's system via a specially crafted liveup.haz
file from a malicious web site.

Successful exploitation requires that the user is tricked into
visiting a malicious web site or requires a site hosting LiveCall to
e.g. have some exploitable cross-site scripting vulnerabilities.

The vulnerability has been reported in versions 2004.6.25.1 and
2005.6.21.1. Other versions may also be affected.

SOLUTION:
The vulnerability has reportedly been fixed in the latest version.

PROVIDED AND/OR DISCOVERED BY:
Neo and Park Gyu Tae
