Secunia

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.
