README-SUSE.txt for apache2-mod_nss
==============================================================================
Rationale:
The apache2-mod_nss package was added to the SLES11 codebase to satisfy the
increased demand for a TLSv1.2 capable crypto solution for the apache
webserver, as an enhancement in parallel to the mod_ssl package that comes
with the apache2 package set.
SSL/TLS support in the apache2 package is normally provided by mod_ssl, the
apache module that provides SSL/TLS using the openssl crypto suite. The
specific version in SLES11-SP2 and newer is "0.9.8j", which support TLS of
version 1.0 only. TLSv1.2 can only be provided by versions that are not
compatible with the large variety of packages contained in SLES. The
alternative is to make use of the crypto routines provided by mozilla-nss.
The configuration of mod_nss is similar to that of mod_ssl, but some the
individual options expect different values; as a consequence, a simple
conversion of option names does not work as desired.
------------------------------------------------------------------------------
Converting SSL/TLS certificates:
Because mod_nss uses a database format for the server and CA certificates
and the private key, existing mod_ssl-based certificates need to be converted
to be used by mod_nss.
The SUSE package apache2-mod_nss contains the perl script
/usr/sbin/mod_nss_migrate.pl
that can do that work for you. It may lead to satisfactory results, but in
case it doesn't, here is what it does when it converts mod_ssl to mod_nss
key/certificate storage:
# we make a backup. Good practice...
old /etc/apache2/mod_nss.d
# initialize the database; this creates a NEW database!
certutil -N -d /etc/apache2/mod_nss.d
# convert the existing openssl key and the certificate to pkcs#12 format, uses temporary password "foo":
openssl pkcs12 -export -in your_certificate_file.crt -inkey your_keyfile.key -out server.p12 -name \"Server-Cert\" -passout pass:foo
# import the pkcs#12 file into the freshly created NSS database, again temporary password "foo":
pk12util -i server.p12 -d /etc/apache2/mod_nss.d -W foo
# the last step: -n specifies a name that the certificate can be referred to
# in an easy way from within apache config files; you may use a name of your
# choice, provided you use the same string to reference it in mod_nss.
# Often, the subject of a certificate is used for this.
# set SUBJECT=your_subject from the output of "openssl x509 -subject -in your_certificate_file.crt"
# certutil -A -n $SUBJECT -t \"CT,,\" -d /etc/apache2/mod_nss.d -i your_ca_certificate.pem
You are basically done now.
Use the command
certutil -d /etc/apache2/mod_nss.d -L
to list the certificates contained in the NSS database.
More options of the certutil utility are shown with
certutil -h # short help
certutil --help # longer help
------------------------------------------------------------------------------
TLS versions:
This package has a direct dependency on mozilla-nss of version 3.15.1 or
higher, as TLSv1.2 support first came with this version. The specification of
TLS versions is done with the NSSProtocol directive in apache. Contrary to
the SSLProtocol option from mod_ssl, the NSSProtocol directive specifies a
range of versions, not a list.
The default configuration file that comes with the apache2-mod_nss package
is /etc/apache2/conf.d/mod_nss.conf and reads as follows:
NSSProtocol TLSv1.0,TLSv1.1,TLSv1.2
Please note that SSLv2 support is not provided by mod_nss. If you require
the deprecated SSLv2 protocol, you may need to revert to mod_ssl.
Please read through the comments on top of the file
/etc/apache2/conf.d/mod_nss.conf for more information about usage and
configuration of mod_nss.
Thank you,
Roman Drahtmueller <draht@suse.com>

This is CVE-2013-4566:
The flaw is in the NSSVerifyClient (which is equivalent to mod_ssl's
SSLVerifyClient) setting enforcement. If 'NSSVerifyClient none' is set
in the server / vhost context (i.e. when server is configured to not
request or require client certificate authentication on the initial
connection), and client certificate authentication is expected to be
required for a specific directory via 'NSSVerifyClient require'
setting, mod_nss fails to properly require certificate authentication.
Remote attacker can use this to access content of the restricted
directories.
Reported by Thomas Hoger <thoger@redhat.com>.

* Support for per-directory reconfigured SSL connection parameters.
*
* This is implemented by forcing an SSL renegotiation with the
* reconfigured parameter suite. But Apache's internal API processing
* makes our life very hard here, because when internal sub-requests occur
* we nevertheless should avoid multiple unnecessary SSL handshakes (they
* require extra network I/O and especially time to perform).
*
* But the optimization for filtering out the unnecessary handshakes isn't
* obvious and trivial. Especially because while Apache is in its
* sub-request processing the client could force additional handshakes,
* too. And these take place perhaps without our notice. So the only
* possibility is to explicitly _ask_ OpenSSL whether the renegotiation
* has to be performed or not. It has to performed when some parameters
* which were previously known (by us) are not those we've now
* reconfigured (as known by OpenSSL) or (in optimized way) at least when
* the reconfigured parameter suite is stronger (more restrictions) than
* the currently active one.

* Override of NSSCipherSuite
*
* We provide two options here:
*
* o The paranoid and default approach where we force a renegotiation when
* the cipher suite changed in _any_ way (which is straight-forward but
* often forces renegotiations too often and is perhaps not what the
* user actually wanted).
*
* o The optimized and still secure way where we force a renegotiation
* only if the currently active cipher is no longer contained in the
* reconfigured/new cipher suite. Any other changes are not important
* because it's the servers choice to select a cipher from the ones the
* client supports. So as long as the current cipher is still in the new
* cipher suite we're happy. Because we can assume we would have
* selected it again even when other (better) ciphers exists now in the
* new cipher suite. This approach is fine because the user explicitly
* has to enable this via ``NSSOptions +OptRenegotiate''. So we do no
* implicit optimizations.

A comma-separated string that lists the basic protocols that the server
can use (and clients may connect with). It doesn't enable a cipher
specifically but allows ciphers for that protocol to be used at all.<br>
<br>
Options are:<br>
<ul>
<li><code>SSLv3</code></li>
<li><code>TLSv1 (legacy only; replaced by TLSv1.0)</code></li>
<li><code>TLSv1.0</code></li>
<li><code>TLSv1.1</code></li>
<li><code>TLSv1.2</code></li>
<li><code>All</code></li>
</ul>
Note that this differs from mod_ssl in that you can't add or subtract
protocols.<br>
<br>
If no NSSProtocol is specified, mod_nss will default to allowing the use of
the SSLv3, TLSv1.0, TLSv1.1, and TLSv1.2 protocols, where SSLv3 will be set to be the
minimum protocol allowed, and TLSv1.2 will be set to be the maximum protocol
allowed.
<br>
If values for NSSProtocol are specified, mod_nss will set both the minimum
and the maximum allowed protocols based upon these entries allowing for the
inclusion of every protocol in-between. For example, if only SSLv3 and TLSv1.2
are specified, SSLv3, TLSv1.0, TLSv1.1 and TLSv1.2 will all be allowed, as NSS utilizes
protocol ranges to accept all protocols inclusively
(TLS 1.2 -&gt;TLS 1.1 -&gt; TLS 1.0 -&gt; SSL 3.0), and does not allow exclusion of any protocols
in the middle of a range (e. g. - TLS 1.0).<br>
<br>
Finally, NSS will always automatically negotiate the use of the strongest
possible protocol that has been specified which is acceptable to both sides of
a given connection.<br>

# Configuration for mod_nss starts in this file.
#
# Contents:
# 1) generic information about mod_nss and its relation to mod_ssl
# 2) initialization and loading of the apache module in the SUSE framework
# 3) hints on specifics for the configuration.
#..............................................................................
#
# 1) generic information about mod_nss and its relation to mod_ssl
#
# Concurrency of apache crypto modules:
#
# mod_nss implements SSL/TLS protocol support for the apache webserver and
# is an alternative to mod_ssl. Both modules can be initialized at the same
# time, but, obviously, the protocol handlers ("SSLEngine on" for mod_ssl
# and "NSSEngine on" for mod_nss) cannot be active simultaneously, at a
# global scope, or in the context of a VirtualHost configuration directive
# block.
#
# If for a port that apache listens on, only one VirtualHost section
# has the directive "NSSEngine" set to "on", it will have precedence over
# all other VirtualHost declarations (that may have SSLEngine set to on
# in their context). A simultaneaous operation of both modules for different
# VirtualHosts on the same IP Address and port is not possible.
#
# Reason:
# The brwoser/client connects to the web server's port 443 and initializes
# an SSL/TLS handshake. If SSLv3 protocol is used, there is no way for the
# client to specify the host that it wants to connect to, unless the crypto
# has been fully initialized already. Similarly, the server cannot present
# the correct certificate to the browser that matches the requested hostname.
# As a consequence, if endpoints are limited to SSLv3, only one web server and
# no virtual servers can be bound to one address. Each additional web server
# would need a new IP address.
# Starting with TLSv1.0, the protocol comes with the Server Name Indication
# (SNI) extension that allows the client to specify the requested hostname
# before the cryptographical part of the protocol is initialized. However,
# this type of hostname distinction is handled by the crypto library in
# combination with mod_ssl or mod_nss, not by apache's core.
# This means that in a dual mod_ssl and mod_nss configuration that is not
# selective on IP addresses, and even if you use TLSv1.0 and newer only,
# only one out of mod_ssl or mod_nss will be active.
# Consequences:
# a) If you need support for encrypted connections using _both_ mod_nss and
# mod_ssl, you should consider using more than one IP addresses, and
# configure the server's crypto engine/module bound to the IP address.
# b) If you do NOT need both mod_nss and mod_ssl simultaneaously in apache,
# it is recommended to decide for one and deactivate the other.
#
# Certificates:
# The directory /etc/apache/mod_nss.d contains everything that mod_nss
# needs: keys, certificates. The default configuration has reference
# to .db files in /etc/apache/mod_nss.d that shall illustrate how the
# configuration should/could look like.
#
# In addition to providing a central location to store keys and certificates,
# /etc/apache/mod_nss.d may also contain configuration files that are
# included directly after this documentation text. Note that only files
# named *.conf are included!
#
#
#..............................................................................
# 2) initialization and loading of the apache module in the SUSE framework
#
# To get SSL/TLS support activated in apache, two things have to be done:
# a) configure and initialize the crypto module that provides the SSL/TLS
# protocol support in apache
# b) tell apache to listen on the port where browsers typically connect to
# if they want to talk SSL/TLS. Normally TCP port 443.
#
# about a):
# The apache module (a shared object file) is loaded by the framework if
# the config variable APACHE_MODULES set in /etc/sysconfig/apache2
# contains the module name ("nss", without the preceding "mod_").
# Either you edit /etc/sysconfig/apache2 manually and add the module name
# nss to the other modules in APACHE_MODULES, or you let the command
#
# a2enmod nss
#
# do this for you. "a2enmod -d nss" reverses that change and disables mod_nss
# again.
# All of the configuration directives set in the default config files are
# conditional for the loading of the module, which is evident when looking at
# the "<IfModule mod_ssl.c>" that shows up further below.
#
# about b)
# The Listen directive in /etc/apache2/listen_nss.conf is conditional on
# the server-define "SSL". Add the word SSL to the variable
# APACHE_SERVER_FLAGS in the file /etc/sysconfig/apache2 .
#
# Please note that /etc/apache2/listen.conf is read/included from the apache
# main configuration file /etc/apache2/httpd.conf;
# /etc/apache2/listen_nss.conf is read from this file, just below.

# SSL Protocol:
# Cryptographic protocols that provide communication security.
# NSS handles the specified protocols as "ranges", and automatically
# negotiates the use of the strongest protocol for a connection starting
# with the maximum specified protocol and downgrading as necessary to the
# minimum specified protocol that can be used between two processes.
# Since all protocol ranges are completely inclusive, and no protocol in the
# middle of a range may be excluded, the entry "NSSProtocol SSLv3,TLSv1.2"
# is identical to the entry "NSSProtocol SSLv3,TLSv1.0,TLSv1.1,TLSv1.2".
# Here, we disable SSLv3, but allow TLSv1.0 through TLSv1.2 :
NSSProtocol TLSv1.0,TLSv1.1,TLSv1.2
# SSL Certificate Nickname:
# The nickname of the RSA server certificate you are going to use.
NSSNickname Server-Cert
# SSL Certificate Nickname:
# The nickname of the ECC server certificate you are going to use, if you
# have an ECC-enabled version of NSS and mod_nss
#NSSECCNickname Server-Cert-ecc
# Server Certificate Database:
# The NSS security database directory that holds the certificates and
# keys. The database consists of 3 files: cert8.db, key3.db and secmod.db.
# Provide the directory that these files exist.
NSSCertificateDatabase @apache_conf@/mod_nss.d
# Database Prefix:
# In order to be able to store multiple NSS databases in one directory
# they need unique names. This option sets the database prefix used for
# cert8.db and key3.db.
#NSSDBPrefix my-prefix-
# Client Authentication (Type):
# Client certificate verification type. Types are none, optional and
# require.
#NSSVerifyClient none
#
# Online Certificate Status Protocol (OCSP).
# Verify that certificates have not been revoked before accepting them.
#NSSOCSP off
#
# Use a default OCSP responder. If enabled this will be used regardless
# of whether one is included in a client certificate. Note that the
# server certificate is verified during startup.
#
# NSSOCSPDefaultURL defines the service URL of the OCSP responder
# NSSOCSPDefaultName is the nickname of the certificate to trust to
# sign the OCSP responses.

#NSSOCSPDefaultURL http://example.com/ocsp/status
#NSSOCSPDefaultName ocsp-nickname
# Access Control:
# With SSLRequire you can do per-directory access control based
# on arbitrary complex boolean expressions containing server
# variable checks and other lookup directives. The syntax is a
# mixture between C and Perl. See the mod_nss documentation
# for more details.
#<Location />
#NSSRequire ( %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
# and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
# and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"} \
# and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
# and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20 ) \
# or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
#</Location>
# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation. This means that
# the standard Auth/DBMAuth methods can be used for access control. The
# user name is the `one line' version of the client's X.509 certificate.
# Note that no password is obtained from the user. Every entry in the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables: SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
# server (always existing) and the client (only existing when client
# authentication is used). This can be used to import the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*' environment variables.
# Per default this exportation is switched off for performance reasons,
# because the extraction step is an expensive operation and is usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o StrictRequire:
# This denies access when "NSSRequireSSL" or "NSSRequire" applied even
# under a "Satisfy any" situation, i.e. when it applies access is denied
# and no other module can change it.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation handling when SSL
# directives are used in per-directory context.
