TITLE:
Help Center Live Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA15401

VERIFY ADVISORY:
http://secunia.com/advisories/15401/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
From remote

SOFTWARE:
Help Center Live 1.x
http://secunia.com/product/4459/

DESCRIPTION:
James Bercegay has reported some vulnerabilities in Help Center Live,
which can be exploited by malicious people to conduct cross-site
scripting, script insertion and SQL injection attacks.

1) Input passed to the "find" parameter in "index.php" isn't properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

2) Input passed to the name and message fields when requesting a
chat, and the message body when opening a trouble ticket isn't
properly sanitised before being used. This can be exploited to inject
arbitrary HTML and script code, which will be executed in a user's or
administrator's browser session in context of an affected site when
the malicious user data is viewed.

3) Certain input isn't properly sanitised before being used in a SQL
query. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

It is also possible to trick an administrator into performing certain
actions (e.g. deleting attachments) on an affected site when accessing
a specially crafted URL while logged in.

SOLUTION:
The vulnerabilities have reportedly been fixed by the vendor.

PROVIDED AND/OR DISCOVERED BY:
James Bercegay, GulfTech Security Research Team.
