Nessus vulnerabilities after upgrading to 7.16 CU5


Last week we upgraded to 7.16 CU5. A few days later our security team did their weekly scans and revealed SSL2/3 issues on the servers. I put a ticket into Citrix and they think it is our Netscaler, which we haven't touched in awhile.


Looking up more info on it, ----

SSLv3 is enabled and the server supports at least one cipher.
    Explanation: TLS 1.0 and SSL 3.0 cipher suites may be used with SSLv3


It appears CU5 is talking on SSL 3, on port 5986, has anyone come across this before?

Plugin is 20007.  Since my post yesterday, we discovered that it may be related to the server O/S instead, waiting for the NESSUS scan results to come back.


I ran:

winrm e winrm/config/listener

and found winRM on this port.

I used IISCrypto to disable SSL2/3 and TLS 1.0. and rebooted.


Very odd to say the least that the issue came up on all Windows 2012 R2 servers, days after the the CU5 upgrade. Wonder if a Windows update snuck in and turn on SSL and TLS.
