Janek Vind has reported some vulnerabilities in PHP-Nuke, potentially allowing malicious people to reveal sensitive information, conduct cross-site scripting, script insertion, and SQL injection attacks.

1) Path information can be disclosed in error pages by passing invalid input or accessing scripts directly.

Examples:
/modules/Web_Links/voteinclude.php
/modules.php?name=Statistics&op=convert_month
/modules.php?name=Journal&file=add&filelist=[some_data]
/modules.php?name=Journal&file=modify&filelist=[some_data]

2) Input passed to various parameters in certain modules 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=Journal&file=friend&jid=2&yun=[malicious_code]
/modules.php?name=Journal&file=friend&jid=2&ye=[malicious_code]
/modules.php?name=Journal&file=add&filelist[]=[malicious_code]
/modules.php?name=Journal&file=modify&filelist[]=[malicious_code]
/modules.php?name=Journal&file=delete&jid=[malicious_code]&forwhat=waraxe
/modules.php?name=Journal&file=comment&onwhat=[malicious_code]
/modules.php?name=Journal&file=commentsave&rid=[malicious_code]

3) The problem is that the "title" parameter in the Journal module isn't properly santised allowing malicious HTML and script to be included. The included code will be executed when a user or administrative user reads the journal index or the journal entry.

4) Certain functions in the Journal module fails to verify if a user is authenticated, allowing malicious people to delete comments and add new journal entries.

5) The Journal module fails to verify input passed to the "forwhat" parameter properly before it is used in a SQL query. This can be exploited to manipulate SQL queries, an example has been posted which reveals the md5 encoded administrative password.

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