LimeSurvey sUser Parameter SQL Injection

high Nessus Plugin ID 38694

Language:

Synopsis

The remote web server contains a PHP script that is prone to a SQL injection attack.

Description

The remote host is running LimeSurvey, an open source tool for online surveys.

The version of LimeSurvey installed on the remote host fails to sanitize user-supplied input passed to the 'sUser' argument in the 'checkUser()' method of the 'LsrcHelper' class in 'admin/remotecontrol/lsrc.helper.php' before using it to construct database queries. Regardless of PHP's 'magic_quotes_gpc' setting, an unauthenticated attacker can exploit this issue to manipulate database queries to, for example, bypass authentication and gain administrative access, which in turn could allow for arbitrary code execution.

Solution

Either upgrade to LimeSurvey 1.82 or later, or remove the application's 'admin/remotecontrol' directory.
