These bugs were published in full-disclosure about 2 weeks ago (CVE :
CVE-2007-0373, CVE-2007-0374 and CVE-2007-0375, CVE-2007-0387) .
In Mambo 4.6.1 and Joomla 1.0.11 (and 1.5 Beta) , the 'id' parameter can
cause sql injection when cancelling content editting . Other versions maybe
affected too . This problem has been solved in Joomla 1.0.12 .
Several other sql injections exist in Joomla! 1.5.0 Beta :
The 'searchword' parameter is not checked properly before be used
in the sql query in several files :
In both 'plugins/search/content.php' and 'plugins/search/weblinks.php'
files, the '$where' variable is not checked .
Also, in 'plugins/search/contacts.php', 'plugins/search/categories.php' and
'plugins/search/sections.php' files, the '$text' var is affected. For example :
File plugins/search/sections.php, Line 75 :
:: $query = "SELECT a.name AS title,"
:: . "\n a.description AS text,"
:: . "\n '' AS created,"
:: . "\n '2' AS browsernav,"
:: . "\n a.id AS secid, m.id AS menuid, m.type AS menutype"
:: . "\n FROM #__sections AS a"
:: . "\n LEFT JOIN #__menu AS m ON m.componentid = a.id"
** . "\n WHERE ( a.name LIKE '%$text%'"
** . "\n OR a.title LIKE '%$text%'"
** . "\n OR a.description LIKE '%$text%' )"
:: . "\n AND a.published = 1"
:: . "\n AND a.access <= " .$user->get( 'gid' )
:: . "\n AND ( m.type = 'content_section' OR m.type = 'content_blog_section' )"
:: . "\n GROUP BY a.id"
:: . "\n ORDER BY $order"
The search word is limited to 20 characters, so this bug doesnt seem to be

Another sql injection exists in "check()" function . The 'email' parameter is
not checked properly :
File libraries/joomla/database/table/user.php, Line 104 :
:: $query = "SELECT id"
:: . "\n FROM #__users "
** . "\n WHERE email = '$this->email'"
:: . "\n AND id != $this->id"
This is reachable by normal users, and can be dangerous .
The SVN version had another sql injection (I have not checked the recent SVN
version after my post to full-disclosure) :
The 'catid' parameter is not checked properly in "_buildQuery()" function :
File components/com_weblinks/models/category.php, Line 209 :
:: $query = "SELECT *" .
:: "\n FROM #__weblinks" .
** "\n WHERE catid = $this->_id".
:: "\n AND published = 1" .
:: "\n AND archived = 0".
:: "\n ORDER BY $filter_order $filter_order_dir, ordering";

Also, there are several full path disclosure bugs in Joomla 1.5.0 Beta .
Many files call "jimport()" function at the top of the file . So direct access
to these files will expose full path of the script . For example :
