how do I block weak ciphers on Tomcat 4.1.31

2008-05-13 Thread Naqvi Zahid - znaqvi
I have extensively searched the web, but I can't find a definitive
answer on this. Here's the situation.

 

I have tomcat 4.1.31 with Java(TM) 2 Runtime Environment, Standard
Edition (build 1.5.0_15-b04), running on a Solaris 8 box. Due to custom
production apps we can not upgrade tomcat at this time (the transition
to tomcat 6 is in progress but not yet completed). Our security scanner
is reporting the following weak ciphers on the port we use for tomcat.

EXP-DES-CBC-SHA Weak Security

EXP-RC4-MD5 Weak Security

DES-CBC-SHA Weak Security

 

The list of ciphers I have configured in servers.xml is

 

ciphers=SSL_RSA_WITH_RC4_128_MD5,SSL_RSA_WITH_RC4_128_SHA,SSL_DHE_RSA_W
ITH_3DES_EDE_CBC_SHA

 

as you can see none of the weak ciphers detected by the scanner are
listed in the servers.xml. The question is how do I block these weak
ciphers and is it possible that an application other than tomcat might
be providing/serving these ciphers (such as a java certificate etc.) on
the port used by tomcat.

 

 

Thanks for any help you can provide.

You'll need 4.1.32 onwards for the ciphers option work.

If you are worried about this, then there are plenty of other things to 
worry about (http://tomcat.apache.org/security-4.html) and an upgrade to 
4.1.37 is probably in order.

Thanks Mar, I think it makes a lot of sense. I know that we have to
upgrade but can't do it until all the scripts and production stuff is
moved over to TC6.
Thanks for the pointer I will try the upgrade to TC4.1.32 so that the
ciphers option starts to work.
