  • Hunt ctrl-service.log for invocations of the hotfix-removal utility with path traversal sequences (e.g., '../../') pointing to shell scripts in /tmp — indicative of CVE-2026-15410 exploitation.
  • Alert on /var/lib/unit/conf.json containing routes for /__api__/login or /__api__/logout, as these URIs do not exist in legitimate SMA1000 configuration and indicate post-exploitation tampering.
  • Monitor extraweb_access.log for HTTP 200 responses to /__api__/login or /__api__/logout as an indicator of compromise.
  • The Erlang cookie used for unauthenticated RCE via the SSRF tunnel to localhost:1050 is hardcoded; detect use of the value '10ecad5b446e86864832904cd439b6b70262' in network traffic to port 1050.
  • Flag WebSocket upgrade requests (HTTP 101) to /wsproxy with the User-Agent 'SMA Connect Agent' from external/untrusted sources as a strong exploitation indicator.
  • Monitor for access to /tmp/temp.db* on the SMA1000 appliance, consistent with theft of stored session data.
  • Detect pre-exploitation reconnaissance via repeated requests to /auth1.html, /.env, and /api/sonicos/is-sslvpn-enabled against internet-facing SMA1000 appliances.
  • ·CVE-2026-15409 and CVE-2026-15410 do not affect SSL VPN functionality on SonicWall firewalls or the SMA 100 Series product line — scope detection and remediation only to SMA1000 Series appliances.
  • ·For CVE-2026-15410 path traversal, the system only reboots (and executes the payload) if the referenced hotfix file actually exists on disk; a missing file results in no reboot and no execution, which may affect forensic interpretation of reboot events.
  • ·There are no workarounds available for these vulnerabilities; patching to the fixed platform-hotfix versions is the only remediation.
