DESCRIPTION:
Multiple vulnerabilities have been discovered in PBBoard, which can
be exploited by malicious users to conduct script insertion attacks
and compromise a vulnerable system, and by malicious people to
conduct cross-site scripting and SQL injection attacks.

1) Input passed via the "URL" field when setting the location of a
new avatar is not properly sanitised before being used and returned
to the user. This can be exploited to insert arbitrary HTML and
script code which will be executed in a user's browser session when
the malicious data is being viewed.

2) The application insecurely validates uploaded file types. This can
be exploited to execute arbitrary PHP code by uploading a PHP file
with e.g. a ".pht" file extension

3) Input passed via the "username" POST parameter to index.php and
admin.php (when "page" is set to "login" and "login" is set to "1")
is not properly sanitised before being used in SQL queries. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

NOTE: This can further be exploited to bypass the log-in mechanism.

4) Input passed via the "id" parameter (when "page" is set to "forum"
and "show" is set) and via the "username" parameter (when "page" is
set to "profile" and "show" is set) to index.php is not properly
sanitised before being used in SQL queries. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

NOTE: This can further be exploited to conduct cross-site scripting
attacks via SQL error messages.

Successful exploitation of vulnerabilities #3 and #4 requires that
"magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 2.1.1. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
uploaded file types are securely validated.
