TITLE:
PhpWebGallery PHP Code Execution and SQL Injection

SECUNIA ADVISORY ID:
SA32221

VERIFY ADVISORY:
http://secunia.com/advisories/32221/

CRITICAL:
Highly critical

IMPACT:
Manipulation of data, Exposure of sensitive information, System
access

WHERE:
>From remote

SOFTWARE:
PhpWebGallery 1.x
http://secunia.com/advisories/product/6487/

DESCRIPTION:
EgiX has reported two vulnerabilities in PhpWebGallery, which can be
exploited by malicious users to compromise a vulnerable system and by
malicious people to conduct SQL injection attacks.

1) Input passed to the "sort_by" parameter in comments.php is not
properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability may allow e.g.
retrieval of administrator session IDs.

2) Input passed to the "sort" parameter through admin.php to
plugins/event_tracer/event_list.php is not properly sanitised before
being used in a call to "create_function()". This can be exploited to
execute arbitrary PHP code.

Successful exploitation of this vulnerability requires valid
administrator credentials (but see #1).

The vulnerabilities are reported in version 1.7.2. Prior versions may
also be affected.

SOLUTION:
Update to version 1.7.3.
