CVE-2019-0192 : Vulnerability Insights and Analysis
Learn about CVE-2019-0192 affecting Apache Solr versions 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5. Understand the deserialization vulnerability allowing remote code execution and how to mitigate the risk.
Apache Solr versions 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5 are vulnerable to remote code execution due to unsafe deserialization. Attackers can exploit the Config API to configure the JMX server, leading to potential security risks.
Understanding CVE-2019-0192
Apache Solr versions 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5 are affected by a deserialization vulnerability that allows attackers to execute remote code by manipulating the JMX server configuration.
What is CVE-2019-0192?
The vulnerability in Apache Solr versions 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5 enables attackers to exploit the Config API to configure the JMX server via an HTTP POST request, potentially leading to remote code execution.
The Impact of CVE-2019-0192
Exploiting this vulnerability can result in remote code execution on the targeted Solr system, posing a significant security risk to affected systems.
Technical Details of CVE-2019-0192
Apache Solr's vulnerability to deserialization attacks allows threat actors to execute malicious code remotely, compromising system integrity.
Vulnerability Description
The Config API in Apache Solr versions 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5 permits the configuration of the JMX server through an HTTP POST request, enabling attackers to trigger remote code execution via unsafe deserialization.
Affected Systems and Versions
- Product: Apache Solr
- Vendor: Apache Software Foundation
- Versions: 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5
Exploitation Mechanism
Attackers can exploit the vulnerability by directing the Config API towards a malicious RMI server, leveraging Solr's insecure deserialization to execute remote code on the targeted system.
