DESCRIPTION:
Stefan Schurtz has discovered multiple vulnerabilities in MGB, which
can be exploited by malicious users to conduct SQL injection attacks
and by malicious people to conduct cross-site scripting attacks.

1) Input passed via the "p" parameter to index.php is not 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 via the "name", "city", "email", "icq", "aim", "msn",
"hp", and "message" parameters to newentry.php is not properly
sanitised in the "template()" function in includes/functions.inc.php
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.

3) Input passed via the "id" parameter to admin/admin.php (when
"action" is set to "delete") is not properly sanitised in
admin/delete.inc.php before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability requires the "Delete
post" permission.

The vulnerabilities are confirmed in version 0.6.9.1. Other versions
may also be affected.

SOLUTION:
No official solution is currently available.

PROVIDED AND/OR DISCOVERED BY:
Stefan Schurtz.
