Listed in the CISA Known Exploited Vulnerabilities catalog
1 catalogued vulnerability is associated with this product line, 1 of them linked to known ransomware campaigns. CISA lists these as actively exploited.
CISA names product lines and software rather than part numbers, so each row states how it was matched. Confirm against the vendor advisory before acting: this augments vendor data, it does not replace it.
