DO NOT REPLY [Bug 46950] New: SSL renegotiation does not occur when
resource with CLIENT-CERT auth is requested
https://issues.apache.org/bugzilla/show_bug.cgi?id=46950
Summary: SSL renegotiation does not occur when resource with
CLIENT-CERT auth is requested
Product: Tomcat 6
Version: 6.0.18
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Servlet & JSP API
AssignedTo: dev@tomcat.apache.org
ReportedBy: andre@cabine.org
When a part of a webapp requires an SSL connection with a client certificate
there should be an SSL renegotiation to request a client certificate from the
browser.
This is the configuration I added to an webapp that already uses an SSL
connector:
<login-config id="LoginConfig_1">
<auth-method>CLIENT-CERT</auth-method>
<realm-name>WPS</realm-name>
</login-config>
<security-constraint id="SecurityConstraint_1">
<web-resource-collection id="WebResourceCollection_1">
<web-resource-name/>
<url-pattern>/LoginWithCert.do</url-pattern>
<http-method>DELETE</http-method>
<http-method>GET</http-method>
<http-method>POST</http-method>
<http-method>PUT</http-method>
<http-method>HEAD</http-method>
</web-resource-collection>
<user-data-constraint id="UserDataConstraint_4">
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
Requests to /LoginWithCert.do require an SSL connection, if there isn't one,
but no client certificate is requested.

Created an attachment (id=23663)
--> (https://issues.apache.org/bugzilla/attachment.cgi?id=23663)
Patch that makes the Apr connector behave like the non-Apr
This patch will turn on the SSL Client requirement prior to the SSL
renegotiation prompting the browser for one.

The native fixes have been applied to the 1.1.x branch and trunk (1.2.x)
The Tomcat fixes have been applied to trunk (7.0.x) and proposed for 6.0.x and
5.5.x. Note that the 6.0.x/5.5.x patch depends on there being a new tc-native
release

The following configuration works for me. At a guess, you haven't configured
Tomcat to trust the issuer of your client certificate. The browser only prompts
you to select a cert if it has one that the server will trust.
Please use the users list if you need further help configuring your SSL certs.

--- Comment #9 from Mark Thomas <ma...@apache.org> 2009-05-27 06:08:48 PST ---
The proposed patch does not work exactly as intended. It does not trigger
renegotiation, rather it sets SSLVerifyClient for the all future SSL sessions
created by that request processor.
The side effects of this are:
- cert still not prompted for when transitioning from resource that doesn't
require cert to one that does
- subsequent SSL requests handled by that processor will prompt for a cert,
even when not required.
As per comment #7, a fix for this that aligns the APR/native connector
behaviour with the Java connectors will require a change to the native
component of the native connector (to enable the connection to be renegotiated
for the current connection).

There is no <auth-constraint> in the configuration, so of course Tomcat doesn't
ask for a certificate.

OK, I can confirm this when I test with the APR/native connector. Looking for a
fix now...

Ok. So now I changed the security-constraint to:
<security-constraint id="SecurityConstraint_1">
<web-resource-collection id="WebResourceCollection_1">
<web-resource-name/>
<url-pattern>/LoginWithCert.do</url-pattern>
<http-method>DELETE</http-method>
<http-method>GET</http-method>
<http-method>POST</http-method>
<http-method>PUT</http-method>
<http-method>HEAD</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>*</role-name>
</auth-constraint>
<user-data-constraint id="UserDataConstraint_4">
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
Now I get this error when I access the resource:
HTTP Status 400 - No client certificate chain in this request
BUT no certificate was asked in the SSL (re-)negotiation.

It will also be proposed for backport to 5.5.x

What works for you? Did you even read what I said?
How can the browser know if a server trusts a certain certificate or not
without even asking for it?
Let me explain the problem better.
Most of my site runs without client cert checking, so I have
SSLVerifyClient="none" on the connector. But I have one servlet that DOES want
a client certificate and so I configured the security restriction accordingly
in the deployment descriptor. Just that one resource, not the entire site.
It's in these cases that a SSL renegotiation does not occur to ask for the
client certificate. Tomcat only knows that I want a client certificate after
the client sends the http request.
Apache httpd has this feature and someone at the tomcat user's list asked me to
file this as a bug. Maybe it's just a missing feature.

--- Comment #5 from Mark Thomas <ma...@apache.org> 2009-04-15 04:38:10 PST ---
(In reply to comment #4)
> What works for you?
The security constraint and login configuration I posted which requires SSL for
the entire context but only requires user authentication for a single JSP. If I
browse to any resource except the one that requires auth using http I get
switched to https as expected. If I then request the protected resource I get
prompted for my certificate.
> Did you even read what I said?
Yes I did. Quite carefully. Taking that attitude is not going to induce people
to help you.
> How can the browser know if a server trusts a certain certificate or not
> without even asking for it?
This is the way the SSL handshake works. The server provides a client with a
list of trusted certs. If the client doesn't have a user cert issued by one of
the trysted certs the client doesn't waste time prompting the user to select
one.
> Let me explain the problem better.
>
> Most of my site runs without client cert checking, so I have
> SSLVerifyClient="none" on the connector.
That is new information. Your original bug report made no mention of using the
APR/native connector. I'd expect the behaviour to remain the same but I'll
re-test with the native and see.
