A vulnerability in the IP Version 6 (IPv6) packet processing functions of multiple Cisco products could allow an unauthenticated, remote attacker to cause an affected device to stop processing IPv6 traffic, leading to a denial of service (DoS) condition on the device. The vulnerability is due to insufficient processing logic for crafted IPv6 packets that are sent to an affected device. An attacker could exploit this vulnerability by sending crafted IPv6 Neighbor Discovery (ND) packets to an affected device for processing. A successful exploit could allow the attacker to cause the device to stop processing IPv6 traffic, leading to a DoS condition on the device.
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.
