#xss

A cross-site scripting vulnerability has been discovered in the CMS page history tab. This vulnerability can only be exploited if a user with CMS access has posted malicious or unescaped HTML into any of the text fields on a page, and if the "compare mode" option is selected. The HTML will be embedded into the page unescaped. This has been resolved by performing the text comparison in a HTML friendly way.

It is possible for a bad actor with access to the CMS to make use of onmouseover or onmouseout attributes in the WYSIWYG editor to embed malicious javascript.

NorthStar C2, prior to commit 7674a44 on March 11 2024, contains a vulnerability where the logs page is vulnerable to a stored cross site scripting issue. An unauthenticated user can simulate an agent registration to cause the cross site scripting attack and take over a users session. With this access, it is then possible to run a new payload on all of the NorthStar C2 compromised hosts (agents), and kill the original agent. Successfully tested against NorthStar C2 commit e7fdce148b6a81516e8aa5e5e037acd082611f73 running on Ubuntu 22.04. The agent was running on Windows 10 19045.

A non-persistent Cross-Site Scripting (XSS) vulnerability has been identified in the Shopware eCommerce platform within the frontend. This vulnerability may allow an attacker to inject and execute malicious scripts in the context of a victim's web browser.

CHAOS version 5.0.8 is a free and open-source Remote Administration Tool that allows generated binaries to control remote operating systems. The web application contains a remote command execution vulnerability which can be triggered by an authenticated user when generating a new executable. The web application also contains a cross site scripting vulnerability within the view of a returned command being executed on an agent.

The NethServer module installed as WebTop, produced by Sonicle, is affected by a stored cross site scripting vulnerability due to insufficient input sanitization and output escaping which allows an attacker to store a malicious payload as to execute arbitrary web scripts or HTML. Versions 7 and 8 are affected.

Red Hat Security Advisory 2024-2945-03 - Red Hat AMQ Broker 7.12.0 is now available from the Red Hat Customer Portal. Issues addressed include bypass, cross site scripting, denial of service, and deserialization vulnerabilities.

### Impact Stored Cross-site scripting (XSS) enable attackers that have access to backoffice to bring malicious content into a website or application. ### Affected versions Umbraco CMS >= 8.00 ### Patches This is fixed in 8.18.13, 10.8.4, 12.3.7, 13.1.1 by implementing IHtmlSanitizer

The PHP file view/about.php is vulnerable to an XSS issue due to no sanitization of the user agent. At line [53], the website gets the user-agent from the headers through $_SERVER['HTTP_USER_AGENT'] and echo it without any sanitization. In PHP, echo a user generated statement, here the User-Agent Header, without any sanitization allows an attacker to inject malicious scripts into the output of a web page, which are then executed in the browser of anyone viewing that page.

Versions preceding 0.6.1 of the phpxmlrpc/extras project are susceptible to a Cross-Site Scripting (XSS) vulnerability. This vulnerability exists within the class documenting_xmlrpc_server when processing the GET methodName parameter.
