SynopsisThe remote Apache Tomcat server is affected by multiple vulnerabilities.
DescriptionThe version of Apache Tomcat installed on the remote host is 8.5.x prior to 8.5.16. 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.
- 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.
Note that Nessus 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 8.5.16 or later.
