SimpBook Input Validation Hole in Message Posting Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1015451
SecurityTracker URL:  http://securitytracker.com/id/1015451
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jan 6 2006
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 1.0
Description:   A vulnerability was reported in SimpBook. A remote user can conduct cross-site scripting attacks.

The software does not properly filter HTML code from user-supplied input in the message field before displaying the input. A remote user can submit specially crafted input 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 SimpBook 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.

0o_zeus_o0 reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the SimpBook 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.

The report indicates that as a workaround, you can set "html_enable" to "off" in the "config.php" file.

Vendor URL:  codegrrl.com/scripts/simpbook/ (Links to External Site)
Cause:   Input validation error
Underlying OS:   Linux (Any), UNIX (Any), Windows (Any)

Message History:   None.

#
#An input validation vulnerability in SimpBook has been reported, which can
be exploited
#
#by remote users to conduct cross-site scripting attacks.
#
#User-supplied input passed to the "message" field isn't sanitised before
being stored in
#
#the guestbook. This can be exploited to execute arbitrary script code in
the security context
#
#of an affected website, as a result the code will be able to access any of
the target user's
#
#cookies, 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.
#
#Successful exploitation requires that "html_enable" is set to "on" in "
config.php".
#
#This is set to"on" in the default installation.
#
#Solution:
#
#Set "html_enable" to "off" in "config.php" or edit the source code to
ensure that input is properly sanitised.
