luny has reported two vulnerabilities in ChatPat, which can be exploited by malicious people to conduct script insertion and SQL injection attacks.

1) Input passed to the "message" parameter when submitting a chat message 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 chat message is viewed.

2) Input passed to the "Nick Name" field when entering the chat isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been reported in version 1.0. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised.
