DarkFig has discovered some vulnerabilities in Connectix Boards, which can be exploited by malicious users to conduct SQL injection attacks or compromise a vulnerable system.

1) Certain input when updating the signature is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation allows to e.g. gain administrator privileges, but requires a valid user account.

2) The application does not properly verify uploaded smileys. This can be exploited to execute arbitrary PHP code by uploading a malicious file.

Successful exploitation requires administrator privileges (which can be gained by exploiting vulnerability #1).

The vulnerabilities are confirmed in version 0.7. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly filtered and uploaded files are properly verified.
