Two vulnerabilities have been discovered in Wikepage, which can be exploited by malicious people to conduct cross-site scripting attacks or to disclose sensitive information.

1) Input passed to the "wiki" parameter in index.php is not properly sanitised before being used. This can be exploited to disclose the content of arbitrary files via directory traversal attacks.

2) Input passed to the "wiki" parameter in index.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities are confirmed in version Opus 13 2007.2 (Landauer-Büttiker). Other versions may also be affected.

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