Multiple cross-site scripting (XSS) vulnerabilities in index.php in VirtueMart (formerly known as mambo-phpShop) Joomla! eCommerce Edition CMS 1.0.11, and possibly earlier, allow remote attackers to inject arbitrary web script or HTML via the Itemid parameter in a (1) com_contact or (2) subscribe action.

Multiple PHP remote file inclusion vulnerabilities in the Joomlaboard Forum Component (com_joomlaboard) before 1.1.2 for Joomla! allow remote attackers to execute arbitrary PHP code via a URL in the sbp parameter to (1) file_upload.php or (2) image_upload.php, a variant of CVE-2006-3528.

Unspecified vulnerability in JoomlaLib (com_joomlalib) before 1.2.2 for Joomla! allows remote attackers to have an unknown impact, related to "Joomla globals hacked by script kiddies."

Multiple cross-site scripting (XSS) vulnerabilities in Joomla! before 1.0.11 allow remote attackers to inject arbitrary web script or HTML via unspecified parameters in (1) Admin Module Manager, (2) Admin Help, and (3) Search.

Unspecified vulnerability in PEAR.php in Joomla! before 1.0.11 allows remote attackers to perform "remote execution," related to "Injection Flaws."

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.

Unspecified vulnerability in com_content in Joomla! before 1.0.11, when $mosConfig_hideEmail is set, allows attackers to perform the emailform and emailsend tasks.

Joomla! before 1.0.11 does not limit access to the Admin Popups functionality, which has unknown impact and attack 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.

Joomla! before 1.0.11 does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to have an unspecified impact. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in Joomla!.
