Why It Matters

Analysis dossier

Why It Matters

Appsmith is a platform to build admin panels, internal tools, and dashboards. Prior to 2.1, Appsmith's bundled supervisord exposes an XML-RPC interface on port 9001, reachable from outside the container via a Caddy reverse-proxy route at /supervisor/* on the public ingress. Combined with the APPSMITH_SUPERVISOR_PASSWORD exposed via GET /api/v1/admin/env, any authenticated administrator can send arbitrary XML-RPC calls to supervisord and execute OS commands inside the Docker container via twiddler.addProgramToGroup. This vulnerability is fixed in 2.1.

Matched ssrf (CWE-918)

Exposure

  1. Identify affected server-side request features and deployed versions.Telemetry: Application inventory · The specific feature must be confirmed from the advisory. · Rule ssrf

Exploitation evidence

  1. Review unusual outbound connections from the affected service to internal or metadata endpoints.Telemetry: DeviceNetworkEvents · Outbound patterns can support SSRF hunting. · Rule ssrf

Response

  1. Verify the vendor fix and confirm expected egress after deployment.Telemetry: DeviceNetworkEvents · Post-change telemetry helps validate mitigation. · Rule ssrf
