Per ESA-2021-31 [1] the common mitigation is not sufficient for logstash: > The widespread flag -Dlog4j2.formatMsgNoLookups=true is NOT sufficient to mitigate the vulnerability in Logstash in all cases, as Logstash uses Log4j in a way where the flag has no effect. It is therefore necessary to remove the JndiLookup class from the log4j2 core jar, with the following command: Logstash 7.16.1 should be out today to fix this... update even if mitigated: > Users should upgrade to Logstash 6.8.21 or 7.16.1 once they are released (expected Monday 13th December). These releases will replace vulnerable versions of Log4j with Log4j 2.15.0. EDIT: 7.16.1 is out in GitHub, but not yet everywhere on elastic co: https://github.com/elastic/logstash/releases/tag/v7.16.1 [1] https://discuss.elastic.co/t/apache-log4j2-remote-code-execu...
