Detection & IOCsextracted from sources · hover to see the quote

  • Detect shell injection attempts via ProxyCommand in salt-api SSH client arguments
  • Monitor API requests to salt-api for ssh_options fields containing ProxyCommand directives, which indicate exploitation attempts
  • ·Vulnerability only affects SaltStack Salt versions before 3002.5; patch to 3002.5 or later to remediate
  • ·Salt has been deprecated in Red Hat Ceph Storage 2.5 and will not be fixed in that package; treat any RHCS 2 deployments using Salt as permanently exposed
