TITLE:
MySQL HTML Output Script Insertion Security Issue

SECUNIA ADVISORY ID:
SA32072

VERIFY ADVISORY:
http://secunia.com/advisories/32072/

CRITICAL:
Not critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
MySQL 5.x
http://secunia.com/advisories/product/8355/

DESCRIPTION:
Thomas Henlich has reported a security issue in MySQL, which can be
exploited by malicious people to conduct script insertion attacks.

The security issue is caused due to the MySQL command line client not
properly sanitising HTML output. This can be exploited to execute
arbitrary HTML and script code in a MySQL user's browser session by
e.g. tricking the user into generating and viewing the HTML output of
malicious database entries.

Successful exploitation requires that the attacker can insert HTML or
script code into the database and the victim generates HTML output of
malicious data and views the resulting file in a browser.

The security issue is reported in versions 5.0.26, 5.0.37, and
5.0.45. Other versions may also be affected.

SOLUTION:
Do not generate HTML output for databases containing potentially
untrusted values.
