Apache Wicket 6.x before 6.25.0, 7.x before 7.5.0, and 8.0.0-M1 provide a CSRF prevention measure that fails to discover some cross origin requests. The mitigation is to not only check the Origin HTTP header, but also take the Referer HTTP header into account when no Origin was provided. Furthermore, not all Wicket server side targets were subjected to the CSRF check. This was also fixed.

Apache Wicket before 1.5.13, 6.x before 6.19.0, and 7.x before 7.0.0-M5 make it easier for attackers to defeat a cryptographic protection mechanism and predict encrypted URLs by leveraging use of CryptoMapper as the default encryption provider.

The DiskFileItem class in Apache Wicket 6.x before 6.25.0 and 1.5.x before 1.5.17 allows remote attackers to cause a denial of service (infinite loop) and write to, move, and delete files with the permissions of DiskFileItem, and if running on a Java VM before 1.3.1, execute arbitrary code via a crafted serialized Java object.

Cross-site scripting (XSS) vulnerability in the getWindowOpenJavaScript function in org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow in Apache Wicket 1.5.x before 1.5.15, 6.x before 6.22.0, and 7.x before 7.2.0 might allow remote attackers to inject arbitrary web script or HTML via a ModalWindow title.

Multiple cross-site scripting (XSS) vulnerabilities in the (1) RadioGroup and (2) CheckBoxMultipleChoice classes in Apache Wicket 1.5.x before 1.5.15, 6.x before 6.22.0, and 7.x before 7.2.0 allow remote attackers to inject arbitrary web script or HTML via a crafted "value" attribute in a <input> element.

Unspecified vulnerability in Apache Wicket 1.4.x before 1.4.23, 1.5.x before 1.5.11, and 6.x before 6.8.0 allows remote attackers to obtain sensitive information via vectors that cause raw HTML templates to be rendered without being processed and reading the information that is outside of wicket:panel markup.

Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.21 and 1.5.x before 1.5.8 allows remote attackers to inject arbitrary web script or HTML via vectors involving a %00 sequence in an Ajax link URL associated with a Wicket app.

Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.20 allows remote attackers to inject arbitrary web script or HTML via the wicket:pageMapName parameter.

Directory traversal vulnerability in Apache Wicket 1.4.x before 1.4.20 and 1.5.x before 1.5.5 allows remote attackers to read arbitrary web-application files via a relative pathname in a URL for a Wicket resource that corresponds to a null package.

Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.18, when setAutomaticMultiWindowSupport is enabled, allows remote attackers to inject arbitrary web script or HTML via unspecified parameters.
