Multiple PHP remote file inclusion vulnerabilities in Security Images (com_securityimages) component 3.0.5 and earlier for Joomla! allow remote attackers to execute arbitrary code via a URL in the mosConfig_absolute_path parameter in (1) configinsert.php, (2) lang.php, (3) client.php, and (4) server.php.
Multiple unspecified vulnerabilities in Joomla! before 1.0.11, related to unvalidated input, allow attackers to have an unknown impact via unspecified vectors involving the (1) mosMail, (2) JosIsValidEmail, and (3) josSpoofValue functions; (4) the lack of inclusion of globals.php in administrator/index.php; (5) the Admin User Manager; and (6) the poll module.
Joomla! before 1.0.11 omits some checks for whether _VALID_MOS is defined, which allows attackers to have an unknown impact, possibly resulting in PHP remote file inclusion.
The Admin Upload Image functionality in Joomla! before 1.0.11 allows remote authenticated users to upload files outside of the /images/stories/ directory via unspecified vectors.
Multiple unspecified vulnerabilities in Joomla! before 1.0.11 allow attackers to bypass user authentication via unknown vectors involving the (1) do_pdf command and the (2) emailform com_content task.
The com_rss option (rss.php) in (1) Mambo and (2) Joomla! allows remote attackers to cause a denial of service (disk consumption and possibly web-server outage) via multiple requests with different values of the feed parameter.
