CVE-2023-20002 — Cisco Roomos security vulnerability

Medium CVSS 4.4

A vulnerability in Cisco TelePresence CE and RoomOS Software could allow an authenticated, local attacker to bypass access controls and conduct an SSRF attack through an affected device. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to a user of the web application. A successful exploit could allow the attacker to send arbitrary network requests that are sourced from the affected system.

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.
