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.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.
Rockwell Automation has provided a new firmware version, Version 15.6.3, to mitigate these vulnerabilities.
Rockwell Automation encourages users of the affected versions to update to the latest available software versions
addressing the associated risk, and including improvements to further harden the software and enhance its resilience
against similar malicious attacks. Users can find the latest firmware version by searching for their device at the
following web site:
http://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?famID=15
Additional precautions and risk mitigation strategies specific to these types of attacks are recommended in the Rockwell
Automation security release. When possible, multiple strategies should be implemented simultaneously.
