Description:
Aliaksandr Hartsuyeu has discovered some vulnerabilities in 427BB, which can be exploited by malicious people to conduct script insertion and SQL injection attacks, and bypass certain security restrictions.
1) An error in the authentication process can be exploited to login as an arbitrary user by manipulating the "username", "authenticated", and "usertype" cookie parameters.
2) Input passed to the "ForumID" parameter in "showthread.php" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
3) Input passed via the "url" bbcode tag when posting a message isn't properly verified, 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 a malicious link with the "JavaScript" URI handler is followed from a malicious message.
The vulnerabilities have been confirmed in version 2.2.1 and have also been reported in version 2.2. Other versions may also be affected.
Solution:
Update to version 2.3.1.
