Who should care

Administrators and users of Apache MINA SSHD servers that have the GitPgmCommandFactory configured are potentially affected and should upgrade to a fixed version. They should review their server configurations and monitor for suspicious activity. Security teams should also review compensating controls for exposed systems while remediation is scheduled and verified.

Technical summary

The sshd-git component of Apache MINA SSHD allows authenticated SSH clients to execute arbitrary JGit commands, including those that can write files to arbitrary locations. This is due to the GitPgmCommandFactory not properly restricting the available commands. The vulnerability is fixed by whitelisting uncritical commands and ignoring the --output argument for git archive. Affected servers should be upgraded to Apache MINA SSHD version 2.19.0 or 3.0.0-M5.

Defensive priority

Medium

Recommended defensive actions

  • Upgrade to Apache MINA SSHD version 2.19.0 or 3.0.0-M5
  • Review and restrict GitPgmCommandFactory configurations
  • Monitor SSH server logs for suspicious activity
  • Implement additional security controls for SSH access
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
