PhpGedView PGV_BASE_DIRECTORY Parameter Remote File Inclusion

high Nessus Plugin ID 20339

Language:

Synopsis

The remote web server contains a PHP application that is prone to a remote file inclusion attack.

Description

The version of PhpGedView installed on the remote host fails to sanitize user-supplied input to the 'PGV_BASE_DIRECTORY' parameter of the 'help_text_vars.php' script before using it in a PHP 'require' function.

Provided PHP's 'register_globals' setting is enabled, an unauthenticated attacker may be able to exploit this flaw to read arbitrary files on the remote host and/or run arbitrary code, possibly taken from third-party hosts, subject to the privileges of the web server user id.

In addition, the application reportedly fails to sanitize user input to the 'user_language', 'user_email', and 'user_gedcomid' parameters of the 'login_register.php' script, which could be used by an attacker to inject arbitrary PHP code into a log file that can then be executed on the affected host, subject to the permissions of the web server user id.

Solution

Upgrade to PhpGedView 3.3.7 or 4.0 beta 3 and apply the patch referenced in the vendor advisory above.
