DESCRIPTION:
Secunia Research has discovered two vulnerabilities in the JCE
component for Joomla!, which can be exploited by malicious users to
compromise a vulnerable system and by malicious people to conduct
cross-site scripting attacks.
1) Input passed to the "search" parameter in administrator/index.php
(when "option" is set to "com_jce" and "view" is set to "profiles")
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) An error due to the
components/com_jce/editor/extensions/browser/file.php script (when
"chunk" is set to a value greater than "0") not properly verifying
uploaded files can be exploited to execute arbitrary PHP code by
uploading a PHP file with e.g. a ".jpg.pht" file extension.
Successful exploitation of this vulnerability requires "Author"
privileges.
The vulnerabilities are confirmed in version 2.0.21. Prior versions
may also be affected.
SOLUTION:
Update to version 2.1.0.
PROVIDED AND/OR DISCOVERED BY:
Jon Butler, Secunia.
