SMF Shoutbox 1.x (mod for Simple Machines Forum)

DESCRIPTION:
enterth3dragon has discovered a vulnerability in the SMF Shoutbox mod
for Simple Machines Forum, which can be exploited by malicious users
to conduct script insertion attacks.
Input passed to the "sboxText" parameter in sboxDB.php is not
properly sanitised before being stored. This can be exploited to
insert arbitrary HTML and script code, which is executed in a user's
browser session in context of an affected site when the malicious
data is viewed.
In the default settings, successful exploitation requires that both
the attacker and the victim have valid user credentials.
The vulnerability is confirmed in version 1.16b. Other versions may
also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
