[原文]** DISPUTED ** Cross-site scripting (XSS) vulnerability in Fidra Lighthouse CMS 1.1.0 and earlier allows remote attackers to inject arbitrary web script or HTML via the search parameter in a query_string to the home page. NOTE: The vendor disputes this issue, saying "Lighthouse does not in any way make use of the PHP technology. [It] is an application server ... A technology like this cannot be susceptible to client-side cross-site-scripting-attacks on its own, but only applications created based on such a technology. This does not only apply to Lighthouse, but also to Perl, PHP or web applications based on Java Servlet technology." Since the original researcher is known to test demo pages and is sometimes inaccurate, it is likely that this issue will be REJECTED.
Lighthouse CMS contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'search' variable upon submission to the 'index.php' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
The vendor, Fidra Software, has disputed this vulnerability claiming that the product "is not, and never has been, susceptible to attacks like this and does not exhibit any known security issues in this or any other way."
Due to a lack of demo version or free download, OSVDB can not confirm the researcher or vendor's claims.

Lighthouse Lighthouse CMS 1.1
Lighthouse is prone to a cross-site scripting vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.
An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
This issue affects version 1.1; other versions may also be vulnerable.
NOTE: The vendor disputes this issue, stating that Lighthouse is an application server and is not susceptible to client-side cross-site scripting attacks.
No exploit is required.
