Greymatter allows a remote attacker to retrieve a file that contains the administrative login and password stored in plaintext. The issue is due to the package storing this information in a file named "gmrightclick*reg" (where * is a six digit number) and being readable via the web server. With this information, an attacker can login with administrative privileges and have full control over the Greymatter installation.
