CVE Reference:   CVE-2006-0349, CVE-2006-0350   (Links to External Site)
Updated:  Apr 6 2006
Original Entry Date:  Jan 18 2006
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network

Version(s): 2.0
Description:   Aliaksandr Hartsuyeu of eVuln reported a vulnerability in eggblog. A remote user can inject SQL commands. A remote user can also conduct cross-site scripting attacks.

The software does not properly validate user-supplied input. A remote user can supply a specially crafted parameter value to execute SQL commands on the underlying database. The 'id' parameter in 'blog.php' is affected. Other parameters and scripts may be affected.

A demonstration exploit URL is provided:

http://[target]/eggblog/home/blog.php?id=70'%20union%20select%201,2,3,4,5,6,7/*

The 'topic.php' script does not properly filter HTML code from user-supplied input in the message before displaying the input. A remote user can submit a specially crafted message that, when viewed by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the eggblog software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

The original advisory is available at:

Impact:   A remote user can execute SQL commands on the underlying database.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the eggblog software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   The vendor has issued a fixed version (v3.0b).
