VERIFY ADVISORY:
http://secunia.com/advisories/18177/

CRITICAL:
Highly critical

IMPACT:
Exposure of sensitive information, System access

WHERE:
>From remote

SOFTWARE:
PhpGedView 3.x
http://secunia.com/product/6591/
PhpGedView 2.x
http://secunia.com/product/2733/

DESCRIPTION:
rgod has reported some vulnerabilities in PhpGedView, which can be
exploited by malicious people to disclose sensitive information and
compromise a vulnerable system.

1) Input passed to the "PGV_BASE_DIRECTORY" parameter in
"help_text_vars.php" isn't properly verified, before it is used to
include files. This can be exploited to include arbitrary files from
external and local resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed to the "user_language", "user_email", and
"user_gedcomid" parameters when registering isn't properly sanitised
before being stored in the PHP script "authenticate.php". This can be
exploited to inject and execute arbitrary PHP code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities have been reported in version 3.3.7 and prior.

SOLUTION:
Apply patch for version 3.3.7.
