I am failing a server security scan on Windows 2008 R2, with
TLS Protocol Session Renegotiation Security Vulnerability TLS SSL Man In The Middle CVE-2009-3555
The scan results recommend an upgrade to openssl 0.9.8l or higher.
I am using the latest version of tcnative-1.dll (1.1.29 13/02/14) which, as I understand it is built using the native libraries and openssl libraries.
Is the only way I can resolve this is to build tcnative myself with the latest version of openssl?
Looking at the http://tomcat.apache.org/native-doc/ build section I need MS Visual Studio (which I don't have and have never used).
Has anybody else build it? If so I cannot find it.
This result is a false positive. I've performed various tests with various versions of Tomcat using the 1.1.29 APR/native connector and in none of those test did insecure renegotiation occur.
Note that Tomcat - depending on version, connector and configuration may support secure renegotiation.
The most definitive test was with OpenSSL 0.9.8.k (i.e. a version of OpenSSL that is vulnerable to CVE2009-3555 and will attempt an insecure renegotiation). When I try this, the connection blocks and eventually times out.
You need to find a better security scanner.
For completeness, the output of the test was:
$ ./openssl s_client -connect 192.168.23.9:8443
CONNECTED(00000003)
