kspecial has discovered some vulnerabilities in Cholod Mysql based message board, which can be exploited by malicious people to conduct script insertion and SQL injection attacks.

1) Input passed to the "Name", "Subject", and "Message" parameters in "mb.cgi" when posting a 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 user data is viewed.

2) Input passed to the "topicnumber" and "threadnumber" parameters in "mb.cgi" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Some other parameters may also be affected.

The vulnerabilities have been confirmed in the latest available version. Other versions may also be affected.
