Apache Solr RCE Scanner Detail

Vulnerability Overview

Apache Solr 9.1 is found to be vulnerable to a critical RCE flaw. This vulnerability stems from improper input validation and security configuration, allowing attackers to execute arbitrary code remotely.

Vulnerability Details

The vulnerability exploits two main aspects:

  1. Enabling remote streaming through a POST request to the /solr/<collection_name>/config endpoint.
  2. Using the /solr/<collection_name>/debug/dump?param=ContentStreams endpoint to inject a remote JAR file containing malicious Java class code.

The exploitation process involves sending crafted requests that modify Solr's configuration to accept remote streams and execute arbitrary Java classes, leading to potential unauthorized access or control over the affected system.

Possible Effects

  • Unauthorized remote code execution on the server hosting Apache Solr.
  • Potential access to sensitive data stored in the Solr indexes.
  • Compromise of the underlying server infrastructure.
