Patched 4.3.1 SystemVMs (was Re: git commit: updated

If we don’t support TLS v1.0, it will break console proxy on IE etc. Further, what vulnerabilities do TLS v1.0 and v1.1 have?
Here’s the tool to check POODLE vulnerability on your servers: http://packages.shapeblue.com/tools/poodle-checker.sh (taken from RedHat)
Patched systemvm template for 4.3.1 that fixes for ShellShock and POODLE:

Rohit,
The recent fix can solve the issue, but instead if we can use apache2.conf for these directives and remove them from http2.conf and ssl.conf, it makes usage at one place and avoids usage at different places.
As well, if some body downs the lane includes httpd.conf under apache2.conf, then these references can lead to confusion.

Rohit,
As well, we may want to just revert the previous changes done to httpd.conf to keep the configuration of ciphers consistent across files.
There we mentioned to support only TLS1...etc through + logic
Here, we are excluding few protocols from all.

Yes, I figured that this morning and have fixed it for 4.3. Doing it for master/4.5 now.

Rohit,
As well, we may want to just revert the previous changes done to httpd.conf to keep the configuration of ciphers consistent across files.
There we mentioned to support only TLS1...etc through + logic
Here, we are excluding few protocols from all.

Regarding the configurations in httpd.conf, they don't apply to apache server running in our system vms.
We need to put the configuration in “/etc/apache2/mods-enabled/ssl.conf”, if you see apache2.conf it includes ssl.conf “Include mods-enabled/*.conf" not httpd.conf.
I tried using namp, it worked if we put the configuration in ssl.conf.

AFAIK, on SSVM apache2 runs to serve templates/iso/volumes which users download and it uses 443/https and uses a custom SSL certificate if uploaded. If SSL is not enabled then it does not apply.
In case of CPVM, the Java based agent uses an in-memory SSL keystore (that mgmt server sends it when it starts) and it implements its own Java based webservice that serves the console proxy over 443/https, again if SSL is enabled and a SSL certificate was uploaded.
In both cases, if SSL is not enabled (global settings) for SSVM/CPVM these SSL based attacks don’t apply. Other than these components, it’s the ACS mgmt server (tomcat) or the reverse-proxy/LB in front of it that needs to be fixed either in the server.xml file or in respective reverse-proxy (such as nginx) or the LB (netscaler etc). I’m only aware of these components prone to SSL attacks. If there are other areas, we should find and fix them.

Not sure how this applies for us, we use newer openssl version in systemvm templates. This is for some Cisco appliance not related to Debian/openssl.

Hi Rohit,
1. does changing in httpd.conf reflects the setting for apache2? Use the nmap script as suggested below to identify ssl versions on installed system vm template. Check the suggested change works or not.

2. TLSv1.2 is the latest to be used and suggested default, ssl protocol and the ciphers we use leads to vulnerability, the settings for these as well should be available in similar config file. In our code, search for TLS leads to usage at places, and assumption is that it should negotiate the protocol version from configured and available latest version to least, so if TLSv1.2 is configured on server and client supports it, then it should work.

If we don’t support TLS v1.0, it will break console proxy on IE etc. Further, what vulnerabilities do TLS v1.0 and v1.1 have?
Here’s the tool to check POODLE vulnerability on your servers: http://packages.shapeblue.com/tools/poodle-checker.sh (taken from RedHat)
Patched systemvm template for 4.3.1 that fixes for ShellShock and POODLE:
