Description:
Roozbeh Afrasiabi has discovered a vulnerability in MyBB, which can be exploited by malicious people to conduct cross-site request forgery attacks.

The vulnerability is caused due to the application allowing users to perform certain actions via HTTP POST requests without performing any validity checks to verify the user's request. This can e.g. 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.

Example:
Input passed to the "notepad" parameter when editing the personal pad and the "signature" parameter when editing the signature in the user control panel.

NOTE: The "notepad" parameter is sanitised in version 1.03 and later.

The vulnerability has been confirmed in versions 1.02 and 1.10. Other versions may also be affected.
