2021-12-10, Apache Solr affected by Apache Log4J CVE-2021-44228
As detailed below in light of the recent log4j announcement an evaluation has been conducted by TQS to detail any affected software provided by TQS. As part of the Livepoint X platform, Apache Solr is utilized to provide indexing and as such Apache Solr itself has a dependency on Log4j. It is advised by Apache that only public facing instances of this software are most at risk and as such Apache Solr deployments as part of the Livepoint X stack are not under immediate threat.
