CVE-2016-6806

Apache Wicket vulnerable to CSRF attacks

8.8 HighFix available

CVE-2016-6806 is a high vulnerability (CVSS 8.8) in Apache Wicket, published October 2, 2017. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.82%, the 57th percentile. Fixed in org.apache.wicket:wicket-core 6.25.0.

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.
