-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Symantec Vulnerability Research Security Advisory Advisory ID: SYMSA-2008-001 Advisory Title: Lyris ListManager - Multiple Vulnerabilities Author: Tyler Shields tyler_shields (at) symantec (dot) com [email concealed] 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: 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 Affected clients can download a new version and install it over the previous installation.
