CVE-2019-0192: Apache Solr - Deserialization of Untrusted Data

id: CVE-2019-0192

info:
  name: Apache Solr - Deserialization of Untrusted Data
  author: hnd3884
  severity: critical
  description: |
    In Apache Solr versions 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5, the Config API allows to configure the JMX server via an HTTP POST request. By pointing it to a malicious RMI server, an attacker could take advantage of Solr's unsafe deserialization to trigger remote code execution on the Solr side.
