CVE-2022-37033 — Dotcms Dotcms security vulnerability

Medium CVSS 6.5

In dotCMS 5.x-22.06, TempFileAPI allows a user to create a temporary file based on a passed in URL, while attempting to block any SSRF access to local IP addresses or private subnets. In resolving this URL, the TempFileAPI follows any 302 redirects that the remote URL returns. Because there is no re-validation of the redirect URL, the TempFileAPI can be used to return data from those local/private hosts that should not be accessible remotely.

Matched remediation archetype

Server-side request forgery and unintended proxying

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory server-side URL fetchers, webhooks, importers, previews, redirects, proxies, and protocol handlers reachable from untrusted input.
  • Map egress paths to internal services, metadata endpoints, loopback, private address space, and privileged control planes.
  • Review DNS resolution, redirect, proxy, credential-forwarding, and URL parsing behavior without requesting sensitive targets.

Remediate safely

  • Replace arbitrary destinations with named integrations or a strict allowlist of schemes, hosts, ports, and paths.
  • Resolve and validate every destination and redirect hop, then enforce egress policy independently of application checks.
  • Remove ambient credentials and sensitive headers from fetchers; apply response size, time, and content limits.
