Pretty Link Plugin for WordPress 'pretty-bar.php' 'url' Parameter XSS

Medium Nessus Plugin ID 59387


The remote web server hosts a PHP script that is affected by a cross-
site scripting vulnerability.


The version of the Pretty Link Lite plugin for WordPress installed on
the remote host fails to properly sanitize user-supplied input to the
'url' parameter of the 'pretty-bar.php' script before using it to
generate dynamic HTML output. An attacker can leverage this issue to
inject arbitrary HTML and script code into a user's browser to be
executed within the security context of the affected site.

Note that the install is also reportedly affected by an additional
cross-site scripting issue as well as a SQL injection vulnerability;
however, Nessus has not tested for these.


Upgrade to Pretty Link Lite 1.5.4 or later
