Directory traversal vulnerability in PHProjekt 2.1 and earlier allows a remote attacker to conduct unauthorized activities via a dot dot (..) attack on the file module.

PHProjekt 2.0 through 3.1 relies on the $PHP_SELF variable for authentication, which allows remote attackers to bypass authentication for scripts via a request to a .php file with "sms" in the URL, which is included in the PATH_INFO portion of the $PHP_SELF variable, as demonstrated using "mail_send.php/sms".

PHProjekt 2.0 through 3.1 allows remote attackers to view or modify data via requests to certain scripts that do not verify if the user is logged in.

The upload function in PHProjekt 2.0 through 3.1 does not properly verify certain variables related to uploaded data, which allows remote attackers to cause PHProjekt to process arbitrary files.

Multiple SQL injection vulnerabilities in PHProjekt 2.0 through 3.1 allow remote attackers to execute arbitrary SQL commands via the unknown attack vectors.

Directory traversal vulnerability in PHProjekt 2.0 through 3.1 allows remote attackers to read arbitrary files via .. (dot dot) sequences.

The setup routine (setup.php) in PHProjekt 4.2.1 and earlier allows remote attackers to modify system configuration via unknown attack vectors.

PHP remote file inclusion vulnerability in authform.inc.php in PHProjekt 4.2.3 and earlier allows remote attackers to include arbitrary PHP code via a URL in the path_pre parameter.

Cross-site scripting (XSS) vulnerability in PHProjekt 4.2 and earlier allows remote attackers to inject arbitrary web script or HTML via the chatroom text submission form.

PHProjekt 6.0.5 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by Setup/Controllers/IndexController.php.
