Affected and fixed version statements observed in the public BlackTree CVE catalogue. These statements describe vulnerability scope, not publisher support entitlement.

Lifecycle evidence status

This identity is present in BlackTree CVE records, but no product-specific publisher support or retirement history is currently registered in Lifecycle.

A missing support date does not mean the product is supported. CVE publication dates and affected-version ranges must not be interpreted as EOL dates.

CVE-observed version history

CVE	Published	Affected versions	Fixed version information	Publisher evidence
CVE-2020-28220	11 Dec 2020	Modicon M258 Firmware (All versions prior to V5.0.4.11) and SoMachine/SoMachine Motion software (All versions)	Version 5.0.4.11 of the Modicon M258 Logic Controller and the new software version of SoMachine/SoMachine Motion (now called EcoStruxure Machine Expert) no longer exhibit this problem. We recommend customers migrate from the legacy SoMachine/SoMachine Motion software to the new version called EcoStruxure Machine Expert (available here https://www.se.com/ww/en/product-range-download/2226-ecostruxure-machine-expert/ - /software-firmware-tab). Then, update the Modicon M258 Logic Controller firmware to the latestversion through Schneider Electric Software Update (SESU). Note: a reboot of the controller is required.	Update reference ↗

How this record is maintained

The CVE inventory is reconciled automatically from cve.blacktree.nl. Exact identity matches link to existing Lifecycle product or package histories. Unmatched products stay in a prioritised publisher-source research queue, and Lifecycle marks the date gap instead of inferring a support boundary from vulnerability data.
