Description:
syini666 has reported some vulnerabilities in MyBulletinBoard, which can be exploited by malicious people to cause a DoS (Denial of Service), manipulate certain information, and conduct script insertion attacks.

1) Input passed to the subject field when creating a new thread isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed in the main page.

2) Some input passed in the Reputation system isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed in the user configuration panel.

3) The problem is that users can delete or move other users' private messages (PM).

Successful exploitation requires knowledge of the ID number.

4) An unspecified error can be exploited to cause a Denial of Service on a vulnerable server.
