Janek Vind has reported some vulnerabilities in PHP-Nuke, allowing malicious people to conduct Cross Site Scripting and SQL injection attacks.

1) Input passed in the search string in the "Search" module isn't 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 a vulnerable site.

2) The "Search" module fails to verify input passed to the "instory" parameter properly before it is used in a SQL query. This can be exploited to manipulate SQL queries.

3) Path information can be disclosed in error pages by passing invalid input such as "**" or "+" to the "Search" module.

4) Input passed to various parameters in the "Search" module isn't 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 a vulnerable site.

Examples:
modules.php?name=Search&sid=[malicious code]
modules.php?name=Search&query=*&max=[malicious code]
(Requires more than 9 search results)
modules.php?name=Search&query=waraxe&sel1=[malicious code]&type=comments
modules.php?name=Search&a=6&query=*&match=[malicious code]
modules.php?name=Search&query=*&mod3=[malicious code]
(The specific module must be disabled)

5) The "Search" module fails to verify input passed to the "min" and "categ" parameters properly before it is used in a SQL query. This can be exploited to manipulate SQL queries.

This has been reported to affect version 7.3. Other versions may also be affected.
