CVE-2023-7080 · Arbitrary remote code execution within wrangler dev Workers sandbox

Diese Seite enthält Fakten aus öffentlichen Sicherheitsquellen. Lesen Sie vor dem Aktualisieren die Originalmeldung.

The V8 inspector intentionally allows arbitrary code execution within the Workers sandbox for debugging. wrangler dev would previously start an inspector server listening on all network interfaces. This would allow an attacker on the local network to connect to the inspector and run arbitrary code. Additionally, the inspector server did not validate Origin/Host headers, granting an attacker that can trick any user on the local network into opening a malicious website the ability to run code. If wrangler dev --remote was being used, an attacker could access production resources if they were bound to the worker. This issue was fixed in [email protected] and [email protected]. Whilst wrangler dev's inspector server listens on local interfaces by default as of [email protected], an SSRF vulnerability in miniflare https://github.com/cloudflare/workers-sdk/security/advisories/GHSA-fwvg-2739-22v7  (CVE-2023-7078) allowed access from the local network until [email protected]. [email protected] and [email protected] introduced validation for the Origin/Host headers.
