"The remote OT asset is affected by a vulnerability.");
  script_set_attribute(attribute:"description", value:
"A vulnerability was publicly announced in the SSLv3 protocol 
when using a block cipher in CBC mode. The vulnerability exists 
because the block cipher padding is not covered by the message 
authentication code and exposes users to a potential 
man-in-the-middle attack that relies on padding oracles. 
Because weaknesses have previously been discovered in stream ciphers 
such as RC4 in the SSLv3 protocol, the whole protocol should now be 
considered deprecated. This vulnerability is related to the protocol 
itself and is not specific to a particular SSLv3 implementation. 

This plugin only works with Tenable.ot.
