CVE-2020-6998
5.8 · MEDIUMOverview
CVE-2020-6998 is a medium-severity vulnerability affecting rockwellautomation armor_compact_guardlogix_5370_firmware. It was published on July 27, 2022 and has a CVSS 3.1 base score of 5.8 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.8, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The connection establishment algorithm found in Rockwell Automation CompactLogix 5370 and ControlLogix 5570 versions 33 and prior does not sufficiently manage its control flow during execution, creating an infinite loop. This may allow an attacker to send specially crafted CIP packet requests to a controller, which may cause denial-of-service conditions in communications with other products.
Remediation
Check the references section for vendor advisories and patches from rockwellautomation. Update armor_compact_guardlogix_5370_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
