In the MMM::Agent::Helpers::Network::add_ip function in MySQL Multi-Master Replication Manager (MMM) mmm_agentd 2.2.1 (for FreeBSD), 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

CVE-2017-14477 is a critical remote command execution flaw in MySQL Multi-Master Replication Manager mmm_agentd 2.2.1 for FreeBSD. If an attacker can connect to the agent’s TCP service, they may run commands with the agent process privileges. This is high urgency where MMM is still deployed or exposed.

Executive priority

Treat as urgent for any confirmed MMM deployment. Prioritize internet-facing or broadly reachable agents first, then legacy internal systems. If MMM is not present, document non-exposure.

Technical view

The issue is a shell command injection in MMM::Agent::Helpers::Network::add_ip. A crafted MMM protocol message to mmm_agentd can result in arbitrary command execution as the mmm_agentd process. The CVSS 3.0 score is 9.8 because exploitation is network-based, low complexity, unauthenticated, and requires no user interaction.

Likely exposure

Exposure is most likely on legacy FreeBSD systems running MySQL MMM mmm_agentd 2.2.1, especially where the agent TCP service is reachable from untrusted networks or broad internal segments.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation evidence. The vulnerability is still operationally serious because the source states any attacker able to initiate a TCP session with mmm_agentd can trigger it.

Researcher notes

The source bundle identifies MMM 2.2.1 for FreeBSD and the add_ip helper as the vulnerable code path. Evidence does not include exploit-in-the-wild confirmation, CWE mapping, or a named patch, so avoid assuming more affected versions or a specific fix.

Mitigation direction

  • Identify any MySQL MMM mmm_agentd 2.2.1 deployments, especially on FreeBSD.
  • Restrict mmm_agentd TCP access to trusted replication management hosts only.
  • Remove or isolate legacy MMM deployments that are no longer required.
  • Check Talos and vendor guidance for fixed packages or supported migration paths.
  • Monitor affected hosts for unexpected commands or MMM agent behavior.

Validation and detection

  • Inventory hosts for MySQL MMM and confirm exact mmm_agentd versions.
  • Verify whether mmm_agentd is listening on TCP and from which networks it is reachable.
  • Review firewall rules for unnecessary access to MMM agent services.
  • Check system and application logs for unusual MMM agent activity.
  • Confirm remediation by documenting version, access controls, and remaining exposure.
