A security issue and two vulnerabilities have been discovered in Advanced Electron Forum (AEF), which can be exploited by malicious users to disclose certain system information and conduct SQL injection attacks and by malicious people to conduct cross-site request forgery attacks.

1) Input passed via the filename when uploading attachments is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is disabled.

2) Input passed via the "avatargalfile" parameter when changing the avatar image is not properly verified before an error message is returned. This can be exploited to determine the existence of files on the system via directory traversal attacks.

3) The application's web interface allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. edit administrator's profile settings by tricking a logged in administrator into visiting a malicious web site.

The security issue and the vulnerabilities are confirmed in version 1.0.9. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised and verified. Do not browse untrusted websites or follow untrusted links while logged in to the application.
