Web Editor (LWE) itself (without cloud) is not affected. 3) LOGO! web project on cloud includes "log4j" but don't use functions of "log4j". But there is a workaround for it, see attachment. 4) No LOGO! hardware module has a relation to "log4j" - not affected. Attachment Apache Log4j Vulnerability Mitigation.doc (675 Downloads)

Peterako Experienced Member Joined: 3/27/2009 Last visit: 9/7/2025 Posts: 97 Rating: (6)	Is there a update to this subject.??? Ipersonally install all PLC's in a isolated (hardware level) network so i do not think personally to be affected. Even then for this forum it will be good if we have a final answer and if required solution. Thanks , all the best wishes during the holidays.

Especially on the LOGO! related there is no update because since the update V1.3 of the CERT it has been written that the LOGO! contrary to the statements in the first 3 CERT's is not affected.
