Severity: High
Vulnerability Published: 2019-10-29
Patch Published: 2019-12-29
CVE [?]: CVE-2019-17558
CPE [?]: cpe:/a:apache:solr

Synopsis

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

Description

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.

Solution

Upgrade to Apache Solr version 8.4.0 or later.
