Lostmon has discovered two vulnerabilities in Vikingboard, which can be exploited by malicious users to conduct script-insertion attacks, and malicious people to conduct cross-site scripting attacks.
1) Input passed via the URL is not properly sanitised in inc/lib/screen.php. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires that the target uses a browser that does not URL encode requests (e.g. Internet Explorer).
2) Input passed to the "title" parameter in post.php is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.
The vulnerabilities are confirmed in version 0.1.2.
