ht://dig Input Validation Hole in 'config' Parameter Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1013078
SecurityTracker URL:  http://securitytracker.com/id/1013078
CVE Reference:   CVE-2005-0085   (Links to External Site)
Updated:  Feb 4 2005
Original Entry Date:  Feb 3 2005
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information


Description:   An input validation vulnerability was reported in ht://dig. A remote user can conduct cross-site scripting attacks.

SuSE reported that a cross-site scripting vulnerability was discovered by Michael Krax. The 'config' parameter does not properly filter HTML code from user-supplied input before displaying an error message containing the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the ht://dig 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.

A demonstration exploit URL is provided:

http://[target]/cgi-bin/htsearch?config=%3Cscript%3Ealert('foo')%3C/script%3E

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the ht://dig 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:   No solution was available at the time of this entry.
