PhpGedView PGV_BASE_DIRECTORY Parameter Remote File Include Vulnerability

Vulnerability Assessment Summary
Checks for PGV_BASE_DIRECTORY parameter remote file include vulnerability in PhpGedView

Detailed Explanation for this Vulnerability Assessment

Summary :

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

Description :

The remote host appears to be running PhpGedView, a web-based
genealogy program written in PHP.

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 rights 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 a possible hacker
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.

referenced in the vendor advisory above.
