In the MMM::Agent::Helpers::_execute function in MySQL Multi-Master Replication Manager (MMM) mmm_agentd 2.2.1, a specially crafted MMM protocol message can cause a shell command injection resulting in arbitrary command execution with the privileges of the mmm\_agentd process. An attacker that can initiate a TCP session with mmm\_agentd can trigger this vulnerability.

Security readout for executives and security teams

Plain-English summary

This is a critical remote command execution flaw in MySQL MMM mmm_agentd 2.2.1. Anyone able to open a TCP session to the agent can send a crafted MMM protocol message that may run operating-system commands as the agent process. Treat reachable agents as high-risk infrastructure exposure.

Executive priority

Prioritize immediately if MMM 2.2.1 is present or reachable. This is a critical unauthenticated network RCE affecting database replication management infrastructure, so compromise could affect sensitive data, service availability, and operational trust.

Technical view

CVE-2017-14474 is a command injection issue in MMM::Agent::Helpers::_execute in MySQL Multi-Master Replication Manager mmm_agentd 2.2.1. The CVSS 3.0 score is 9.8 because exploitation is network-accessible, low complexity, unauthenticated, requires no user interaction, and can impact confidentiality, integrity, and availability.

Likely exposure

Exposure is limited to systems running MySQL MMM mmm_agentd 2.2.1 where the agent accepts TCP connections. Risk is highest when that service is reachable from untrusted networks. The provided sources do not identify additional affected versions or products.

Exploitation context

The sources support remote unauthenticated exploitation when an attacker can initiate a TCP session with mmm_agentd. The CVE is not listed as KEV in the provided bundle, and no cited source here confirms active exploitation in the wild.

Researcher notes

The source bundle provides strong impact and attack-vector evidence but limited remediation detail. Avoid assuming affected versions beyond MMM 2.2.1. Focus validation on service reachability, version evidence, privilege context, and whether vendor or distribution advisories provide a patched package.

Mitigation direction

  • Identify and remove internet or broad network access to mmm_agentd.
  • Restrict agent access to trusted replication management hosts only.
  • Check Talos, CVE, and distribution guidance for fixed or supported packages.
  • Disable or retire MMM deployments that cannot be patched or isolated.
  • Review process privileges and reduce mmm_agentd permissions where operationally feasible.

Validation and detection

  • Inventory hosts running MySQL MMM and confirm mmm_agentd versions.
  • Verify whether mmm_agentd 2.2.1 is reachable over TCP.
  • Check firewall and security-group rules around replication management networks.
  • Review host logs for unexpected mmm_agentd activity or process execution.
  • Confirm remediation status against vendor or distribution package information.
