CVE intelligence and bounded remediation
CVE-2020-24264 — Portainer 1.24.1 and earlier is affected by incorrect access control that may lead to remote arbitrary code execution
Portainer 1.24.1 and earlier is affected by incorrect access control that may lead to remote arbitrary code execution. The restriction checks for bind mounts are applied only on the client-side and not the server-side, which can lead to spawning a container with bind mount. Once such a container is spawned, it can be leveraged to break out of the container leading to complete Docker host machine takeover.

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
