Cross-site scripting (XSS) vulnerability in the nBill (com_nbill) component 2.3.2 for Joomla! allows remote attackers to inject arbitrary web script or HTML via the message parameter in an income action to administrator/index.php.
plugins/system/highlight/highlight.php in Joomla! 3.0.x through 3.0.2 and 2.5.x through 2.5.8 allows attackers to unserialize arbitrary PHP objects to obtain sensitive information, delete arbitrary directories, conduct SQL injection attacks, and possibly have other impacts via the highlight parameter. Note: it was originally reported that this issue only allowed attackers to obtain sensitive information, but later analysis demonstrated that other attacks exist.
SQL injection vulnerability in the JV Comment (com_jvcomment) component before 3.0.3 for Joomla! allows remote authenticated users to execute arbitrary SQL commands via the id parameter in a comment.like action to index.php.
Cross-site scripting (XSS) vulnerability in the JoomShopping (com_joomshopping) component before 4.3.1 for Joomla! allows remote attackers to inject arbitrary web script or HTML via the user_name parameter to index.php.
