MyBB calendar.php 'month' Parameter SQLi

critical Nessus Plugin ID 20342


The remote web server hosts a PHP application that is affected by a SQL injection vulnerability.


The version of MyBB installed on the remote host is affected by a SQL injection vulnerability due to improper sanitization of user-supplied input to the 'month' parameter of the calendar.php script. A remote, unauthenticated attacker can exploit this issue to manipulate SQL queries, resulting in the disclosure of sensitive information and modification of data.

Note that the application is also reportedly affected by several additional SQL injection vulnerabilities, many of which can be exploited even if PHP's 'register_globals' setting is disabled and the 'magic_quotes_gpc' setting is enabled. However, Nessus has not tested for these additional issues.


Upgrade to MyBB 1.0 or later.
