New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 9


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 web server is affected by a remote code execution vulnerability. An unauthenticated, remote attacker can exploit this issue, by sending a specially crafted HTTP POST request to the Config API to toggle the params resource loader value for the Velocity Response Writer in the solrconfig.xml file to true.
Enabling this parameter allows to use the velocity template parameter in a specially crafted Solr request to execute arbitrary code.
