SynopsisApache Tomcat 9.0.0.M1 < 9.0.0.M22 Multiple Vulnerabilities
DescriptionThe version of Apache Tomcat installed on the remote host is 9.0.0.M1 or later but prior to 9.0.0.M22. It is, therefore, affected by multiple vulnerabilities :
- A flaw exists in the CORS filter because the HTTP Vary header was not properly added. This allows a remote attacker to conduct client-side and server-side cache poisoning attacks. (CVE-2017-7674)
- A flaw exists in the HTTP/2 implementation that bypasses a number of security checks that prevented directory traversal attacks. A remote attacker can exploit this to bypass security constraints. (CVE-2017-7675)
Note that the scanner has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Apache Tomcat version 9.0.0.M22 or later.
