CVE-2020-11023
Overview
This vulnerability is a cross-site scripting (XSS) flaw caused by improper handling of HTML containing <option> elements within jQuery's DOM manipulation methods such as .html() and .append(). The root cause lies in jQuery's failure to correctly sanitize or neutralize executable code embedded in untrusted HTML input, specifically when processing <option> tags. The affected component is the jQuery DOM manipulation API in versions from 1.0.3 up to but not including 3.5.0.
Vulnerability Description
In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
Impact
An attacker can execute arbitrary JavaScript in the context of the affected web application by supplying crafted HTML input to vulnerable jQuery DOM manipulation methods. This requires the ability to influence or provide HTML content to these functions, which may occur via user input or third-party data sources. Successful exploitation can lead to session hijacking, unauthorized actions on behalf of users, or data theft, impacting confidentiality and integrity of user sessions and application data.
Solution
Upgrade jQuery to version 3.5.0 or later, where this vulnerability is patched as documented in the official jQuery upgrade guide (https://jquery.com/upgrade-guide/3.5/). Debian security advisory DSA-4693 and Fedora package announcements provide patched package versions for their distributions. Refer to these advisories for detailed patch instructions: https://www.debian.org/security/2020/dsa-4693 and https://lists.fedoraproject.org/archives/list/[email protected]/message/QPN2L2XVQGUA2V5HNQJWHK3APSK3VN7K/. Vendors including Oracle and NetApp also reference this fix in their security alerts.
