DESCRIPTION:
Multiple vulnerabilities have been discovered in the Listbingo
component for Joomla, which can be exploited by malicious users to
conduct script insertion attacks and by malicious people to conduct
cross-site scripting and SQL injection attacks.

1) Input passed via the "title" and "address2" parameters to
index.php (when "option" is set to "com_listbingo", "task" is set to
"ads", and "Itemid" is set to a valid value) when editing a listing
is not properly sanitised before being used. This can be exploited to
insert arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the
malicious data is being viewed.

Successful exploitation requires permissions to modify listings.

2) Input passed to the "Itemid" parameter in index.php (when "option"
is set to "com_listbingo") 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.

3) Input passed via the "search_from_price" parameter to index.php
(when "option" is set to "com_listbingo" and "task" is set to
"ads.search") is not properly sanitised before being used in a SQL
query. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

The vulnerabilities are confirmed in version 1.3.1. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
