Apache Solr < 8.4.0 Remote Code Execution

Medium Nessus Plugin ID 132583


The remote web server contains a Java application that is affected by a remote code execution vulnerability.


The version of Apache Solr running on the remote host is at least 5.0.0 and prior to 8.4.0. It is, therefore, affected by a remote code execution vulnerability. A remote code execution vulnerability exists in VelocityResponseWriter due to a flaw in the velocity template parameter. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands with the privileges of Apache Solr.


Upgrade to Apache Solr version 8.4.0 or later.
