Platforms : Linux Vulnerability Type : Design Error Vendor Contacted : 09/02/2002 (no reply) Prior Problems : N/A Current Version : 4.2 (vulnerable) Summary ------- DCP-Portal is a content management system with advanced features like web-based update, link, file, member management, poll, calendar, etc. Its main features include an admin panel to manage the entire site, a smart HTML editor to add news, content, and annoucements, the ability for members to submit news/content and write reviews, and much more. It's an open-source project, which is also supported by FreshMeat. A vulnerability exists in Dcp-Portal, which could allow any remote user to view the full path to the web root. Details ------- If a user submits a HTTP request for the "add_user.php", the system will return an error page containing the path to the web root. The remote attacker may potentially use the disclosed information to aid in further attacks against the host running the vulnerable software. Example: http://www.dcp-portal_host.com.tr/add_user.php This would return; "Warning: Cannot add header information - headers already sent by (output started at /home/usr/www.dcp- portal_host/htdocs/add_user.php:11) in /home/usr/www.dcp- portal_host/htdocs/add_user.php on line 16" Solution -------- Suggested Solution: Cut the lines 10-11 on add_user.php, and paste them at line 20. Vendor did not care to reply or was unreachable.
