CVE intelligence and bounded remediation
CVE-2025-64427 — ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI
ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.0 and prior, due to insufficient validation or restriction of target URLs, an authenticated local user can craft requests that target internal IP addresses (e.g., 127.0.0.1, localhost, or private network ranges). This allows the attacker to interact with internal HTTP/HTTPS services that are not intended to be exposed externally or to local users. No known patch is publicly available.

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.
