SecurityTracker Alert ID: 1007592
CVE Reference: GENERIC-MAP-NOMATCH (Links to External Site)
Date: Aug 28 2003

Impact: Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information

Exploit Included: Yes

Version(s): 8.2

Description: An input validation vulnerability was reported in the eNdonesia portal software. A remote user can conduct cross-site scripting attacks.

Secunia reported that the software does not properly filter HTML code from user-supplied input in the "mod" parameter. A remote user can create a specially crafted URL that, when loaded 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 eNdonesia portal 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 of the form:

http://[some_site]/mod.php?mod=<evil_code>

It is also reported that a remote user can submit a URL with a "lng" parameter that includes a single quote (') to cause the system to display the installation path.
