Nessus tell my hpsmh homepage is vulnerable to logjam
I have try to fix it with this solution
cat /opt/hpws22/apache/conf/dhparams.pem >> /opt/hpws22/apache/conf/ssl.crt/server.crt
And restart hpsmh
But doesn't work.
Why?
Those are ssl params
SSLProtocol -all +TLSv1 +TLSv1.1 +TLSv1.2 # SSL Cipher Suite: # List the ciphers that the client is permitted to negotiate. # See the mod_ssl documentation for a complete list. SSLCipherSuite ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD 5:!DSS:!RC4
Solved! Go to Solution.

Re: Logjam vulnerability
I've add succesfully this line with smhconfig
ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA
but nessus still report error,of course i've added the dhparams.pem to cert.pem file with
cat dhparams.pem >> cert.pem
and restart the app.

SolutionSolution found,
create first the dhparams
openssl dhparam -out dhparams.pem 2048 chmod 600 dhparams.pem
then add this to your certificates,in my case proxy.pem cert.pem
cat dhparams.pem >> /opt/hpsmh/certs/proxy.pem
cat dhparams.pem >> /opt/hpsmh/certs/cert.pem
then modify hpsmh to use correct ciphers
/opt/hpsmh/bin/smhconfig -Z `cat /cip.txt`
cip.txt contain those
ECDH+AESGCM:ECDH+AES256:ECDH+AES128:ECDH+3DES:RSA+AES:RSA+3DES:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!ADH:!AECDH:!MD5:!DSS:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA
Finally reload hpsmh
/opt/hpsmh/bin/hpsmh stop /opt/hpsmh/bin/hpsmh start
