Security Advisory

Advisory ID: SYMSA-2008-001
Advisory Title: Lyris ListManager - Multiple Vulnerabilities
Author: Tyler Shields [email protected]
Release Date: Wednesday, January 21, 2008
Application: Lyris List Manager
Platform: Web Interface
Severity: Remotely Exploitable
Vendor status: Vendor has corrected products and is ok with public release
CVE Number: CVE-2007-6319
Reference: http://www.securityfocus.com/bid/26792

Overview:

"Lyris ListManager is the world's most popular software for creating,
sending, and tracking highly effective email campaigns, newsletters,
and discussion groups. From our new Template and Content Builder to
our Image Library and new HTML editor, ListManager is the smarter,
faster, easier way to manage all the aspects of your email marketing
program."

Details:

1. A user who is subscribed to any list on the ListManager system may
   modify client side information sent to the server related to their
   account, effectively elevating their privileges to list administrator.

2. A user who is subscribed to any list may gain access to arbitrary
   mailing lists by modifying client side information sent to the server.
   Accessing a preexisting mailing list on the ListManager system causes
   the active user to be added as a member or administrator to that list.

3. Once administrative access is granted, a vulnerability in the
   ListManager administrative interface allows an attacker
   to create new accounts that collide with existing accounts. This
   collision will result in overwriting data in the original account
   with the data from the new account.

Vendor Response:

Vendor has acknowledged and corrected the issue in several versions
of the product.

Recommendation:

New versions of each major revision (8.95d, 9.2c and 9.3b), are available
at http://www.lyris.com/support/listmanager/archives.html. Affected
clients can download a new version and install it over the previous
installation.
