Affected products:
-------------------------

Product :               Zenphoto 1.4.3.2 (and maybe older) fixed in 1.4.3.3
Affected function:      printPublishIconLink

----------
Details:
----------

The file admin-news-articles.php calls the function printPublishIconLink
which generates HTML from data stored in the $_GET super global, this can be
used to generate a XSS attack or more seriously, as a admin user need to be
logged in to access the page admin-news-articles.php, a cookie stealing
script.

Example code:
http://127.0.0.1/zenphoto/zp-core/zp-extensions/zenpage/admin-news-articles.
php?date=%22%3E%3Cscript%3Ealert%28%27Cookie%20sealing%20Javascript%27%29;%3
C/script%3E%3C>

--------------------
Suggested fix:
--------------------

Sanitize the $_GET super global on lines 1637 through 1641 in
zenpage-admin-functions.php file
