CVE-2023-7080 – Arbitrary remote code execution within wrangler dev Workers sandbox
https://notcve.org/view.php?id=CVE-2023-7080
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 wrangler@3.19.0 and wrangler@2.20.2. Whilst wrangler dev's inspector server listens on local interfaces by default as of wrangler@3.16.0, 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 wrangler@3.18.0. wrangler@3.19.0 and wrangler@2.20.2 introduced validation for the Origin/Host headers. • https://github.com/cloudflare/workers-sdk/issues/4430 https://github.com/cloudflare/workers-sdk/pull/4437 https://github.com/cloudflare/workers-sdk/pull/4535 https://github.com/cloudflare/workers-sdk/pull/4550 https://github.com/cloudflare/workers-sdk/security/advisories/GHSA-f8mp-x433-5wpf • CWE-269: Improper Privilege Management •
CVE-2023-7079 – Arbitrary remote file read in Wrangler dev server
https://notcve.org/view.php?id=CVE-2023-7079
Sending specially crafted HTTP requests and inspector messages to Wrangler's dev server could result in any file on the user's computer being accessible over the local network. An attacker that could trick any user on the local network into opening a malicious website could also read any file. El envío de solicitudes HTTP especialmente manipuladas y mensajes de inspector al Wrangler's dev server podría hacer que se pueda acceder a cualquier archivo en el equipo del usuario a través de la red local. Un atacante que pudiera engañar a cualquier usuario de la red local para que abra un sitio web malicioso también podría leer cualquier archivo. • https://github.com/cloudflare/workers-sdk/pull/4532 https://github.com/cloudflare/workers-sdk/pull/4535 https://github.com/cloudflare/workers-sdk/security/advisories/GHSA-cfph-4qqh-w828 • CWE-287: Improper Authentication •
CVE-2023-3348 – Directory traversal vulnerability in Cloudflare Wrangler
https://notcve.org/view.php?id=CVE-2023-3348
The Wrangler command line tool (<=wrangler@3.1.0 or <=wrangler@2.20.1) was affected by a directory traversal vulnerability when running a local development server for Pages (wrangler pages dev command). This vulnerability enabled an attacker in the same network as the victim to connect to the local development server and access the victim's files present outside of the directory for the development server. • https://developers.cloudflare.com/workers/wrangler https://github.com/cloudflare/workers-sdk https://github.com/cloudflare/workers-sdk/security/advisories/GHSA-8c93-4hch-xgxp • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
