CVE-2019-25251 — Teradek Vidiu Pro Firmware security vulnerability

Medium CVSS 6.9

Teradek VidiU Pro 3.0.3 contains a server-side request forgery vulnerability in the management interface that allows attackers to manipulate GET parameters 'url' and 'xml_url'. Attackers can exploit this flaw to bypass firewalls, initiate network enumeration, and potentially trigger external HTTP requests to arbitrary destinations.

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.
