Apache Wicket CSRF Bypass via Fetch Meta Headers (9.16.0,10.0.x)
CVE-2024-27439 Published on March 19, 2024
Apache Wicket: Possible bypass of CSRF protection
An error in the evaluation of the fetch metadata headers could allow a bypass of the CSRF protection in Apache Wicket.
This issue affects Apache Wicket: from 9.1.0 through 9.16.0, and the milestone releases for the 10.0 series.
Apache Wicket 8.x does not support CSRF protection via the fetch metadata headers and as such is not affected.
Users are recommended to upgrade to version 9.17.0 or 10.0.0, which fixes the issue.

Weakness Types
What is a Session Riding Vulnerability?
The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. When a web server is designed to receive a request from a client without any mechanism for verifying that it was intentionally sent, then it might be possible for an attacker to trick a client into making an unintentional request to the web server which will be treated as an authentic request. This can be done via a URL, image load, XMLHttpRequest, etc. and can result in exposure of data or unintended code execution.
CVE-2024-27439 has been classified to as a Session Riding vulnerability or weakness.
What is a HTTP Request Smuggling Vulnerability?
When malformed or abnormal HTTP requests are interpreted by one or more entities in the data flow between the user and the web server, such as a proxy or firewall, they can be interpreted inconsistently, allowing the attacker to "smuggle" a request to one device without the other device being aware of it.
CVE-2024-27439 has been classified to as a HTTP Request Smuggling vulnerability or weakness.
