Russ McRee has discovered some vulnerabilities in LightNEasy, which can be exploited by malicious users and malicious people to conduct SQL injection attacks.
1) Input passed via the "page" parameter to LightNEasy.php is not properly sanitised before being used in SQL queries, if it contains a URL-encoded NULL byte. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability requires that "magic_quotes_gpc" is disabled.
2) Input passed via the "id" parameter to LightNEasy.php (when "do" is set to "users" and "action" is set to "edituser") is not properly sanitised before being used in SQL queries, if it contains a URL-encoded NULL byte. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability requires access to the administrative interface and that "magic_quotes_gpc" is disabled.
NOTE: The vulnerabilities can further be exploited to conduct cross-site scripting attacks via SQL error messages.
The vulnerabilities are confirmed in version 3.2.1. Other versions may also be affected.
Solution: Update to version 3.2.4.
