SSLv2-Only Open Ports

Info Nessus Plugin ID 131127


The remote service encrypts communications with an unsupported protocol.


This plugin detects if the remote host has any open ports which only support SSLv2. This protocol has been deprecated since 2011 because of security vulnerabilities and most major SSL libraries such as OpenSSL, NSS, Mbed TLS, and wolfSSL do not provide this functionality in their latest versions.

Nessus 8.9 and later no longer supports SSLv2.


Upgrade encryption protocol used for SSL/TLS traffic to SSLv3, TLS1.0, TLS1.1, TLS1.2, or TLS1.3
