CVE-2016-6806

22
FAUCET Score

CVE-2016-6806 describes a Cross-Site Request Forgery (CSRF) vulnerability in Apache Wicket versions 6.x before 6.25.0, 7.x before 7.5.0, and 8.0.0-M1. The flaw stemmed from an insufficient CSRF prevention mechanism that failed to properly validate cross-origin requests by not consistently checking the Referer HTTP header when the Origin header was absent, and by not applying CSRF checks to all server-side targets. This vulnerability carries a high severity CVSS score of 8.8, indicating a critical risk. It is easily exploitable over the network with low attack complexity, requiring user interaction, and could lead to high impacts on confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. The vulnerability has also garnered minimal community discussion or media coverage, suggesting low public awareness.
