rgod has discovered some vulnerabilities in Papoo, which can be exploited by malicious people to conduct cross-site scripting attacks and SQL injection attacks.

1) Input passed to the "titel" and "ausgabe" parameters in interna/hilfe.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 have been confirmed in version 3 RC3. Other versions may also be affected.

2) Input passed to the "msgid" parameter in forumthread.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been confirmed in version 2.1.3 and 3 RC3. Other versions may also be affected.

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