In the MMM::Agent::Helpers::Network::add_ip function in MySQL Multi-Master Replication Manager (MMM) mmm_agentd 2.2.1 (for Linux), 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 flaw lets an unauthenticated network attacker run operating-system commands on a server running MySQL MMM mmm_agentd 2.2.1 for Linux. If the agent is reachable, compromise can affect confidentiality, integrity, and availability with the agent process privileges.

Executive priority

Treat reachable instances as urgent. The issue enables unauthenticated remote command execution, but prioritization should focus on confirmed MMM 2.2.1 Linux deployments and network reachability to mmm_agentd.

Technical view

CVE-2017-14475 is a command injection in MMM::Agent::Helpers::Network::add_ip. A specially crafted MMM protocol message to mmm_agentd can trigger arbitrary command execution. The CVSS 3.0 score is 9.8 because attack is network-based, low complexity, unauthenticated, and needs no user interaction.

Likely exposure

Exposure is likely limited to environments still running MySQL Multi-Master Replication Manager mmm_agentd 2.2.1 on Linux. Risk is highest where the daemon accepts TCP connections from untrusted networks, broad internal segments, or shared administration networks.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation evidence. They do state an attacker who can initiate a TCP session with mmm_agentd can trigger the vulnerability using a crafted protocol message.

Researcher notes

The key validation question is reachability to mmm_agentd, not just package presence. The bundle identifies the vulnerable add_ip helper and protocol message trigger, but does not provide a named patch, workaround, or confirmed exploitation timeline.

Mitigation direction

  • Inventory systems for MySQL MMM mmm_agentd 2.2.1 on Linux.
  • Restrict mmm_agentd TCP access to trusted replication management hosts only.
  • Place MMM management traffic on isolated administrative networks.
  • Check vendor or Talos guidance for supported updates, replacements, or retirement paths.
  • Remove or disable MMM components that are no longer required.

Validation and detection

  • Confirm installed MySQL MMM and mmm_agentd versions on Linux hosts.
  • Verify whether mmm_agentd is listening on TCP interfaces.
  • Review firewall, security group, and ACL rules controlling agent access.
  • Check process privileges used by mmm_agentd.
  • Review logs for unexpected MMM protocol activity or suspicious child processes.
