DESCRIPTION:
Multiple vulnerabilities have been discovered in the Pay With Tweet
plugin for WordPress, 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 to the "id" attribute to a "paywithtweet" shortcode
is not properly sanitised before being used in a SQL query. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

Successful exploitation requires access rights to modify pages.

2) Input passed to the "link", "title", and "dl" parameters in
wp-content/plugins/pay-with-tweet.php/pay.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.

Successful exploitation requires the victim to be logged into a
twitter account.

The vulnerabilities are confirmed in version 1.1. Prior versions may
also be affected.

SOLUTION:
Update to version 1.2.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor. Additional details provided by Gianluca
Brindisi.
