Title: PHProjekt Arbitrary User Modification Vulnerability
Severity: HIGH
Description:
PHProjekt is a freely available, open source PHP Groupware package. It is actively maintained by the PHPProjekt Development Team.
PHProjekt is prone to an input validation problem which will allow remote attackers to view, modify and delete arbitrary user data. This is done by changing the ID number in the URL. The issue occurs because vulnerable versions of PHProjekt do not attempt to check if the user has authenticated when an arbitrary ID number is specified.
Affected Products:
- PHProjekt PHProjekt 2.0.0
- PHProjekt PHProjekt 2.0.1
- PHProjekt PHProjekt 2.1.0
- PHProjekt PHProjekt 2.1.0a
- PHProjekt PHProjekt 2.2.0
