(Links to External Site)
|
Date: Mar 27 2006
|
Impact: Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
|
Fix Available: Yes
Vendor Confirmed: Yes

Version(s): 2.0.7 and prior versions

Description: A vulnerability was reported in phpAdsNew. A remote user can conduct cross-site scripting attacks.
Several scripts within the admin interface do not properly filter HTML code from user-supplied input (collected by the delivery scripts)
before displaying the input. A remote user can submit specially crafted data. Then, when the affected admin scripts are loaded
by a target administrator, arbitrary scripting code will be executed by the target administrator's browser. The code will originate
from the site running the phpAdsNew 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 login form does not properly
filter HTML code from user-supplied input. 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.
|
Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
phpAdsNew 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 (2.0.8).
