Technical Description

Multiple vulnerabilities have been identified in Joomla!, which could be exploited by attackers to bypass security restrictions or execute arbitrary commands and scripting code.

The first issue is due to input validation errors in the "mosMail()" and "JosIsValidEmail()" functions, which could be exploited by attackers to bypass security checks.

The second flaw is due to an error in the "PEAR.php" script, which could be exploited by attackers to execute arbitrary commands.

The third issue is due to an error in the "administrator/index.php" script that does not include the "globals.php" file.

The fourth flaw is due to insufficient access controls in the Admin "Upload Image", Admin "Popups", and "com_content" functionalities.

The fifth vulnerability is due to errors in the "do_pdf" functionality and in the emailform com_content task, which be exploited by attackers to bypass the authentication process.

The seventh flaw is due to input validation errors in the Admin "Module Manager", Admin "Help", and Search functionalities, which could be exploited by malicious people to conduct cross site scripting attacks.

Other security issues have also been addressed.
