CVE-2024-28863

Description:

During some analysis today on npm's node-tar package I came across the folder creation process, Basicly if you provide node-tar with a path like this ./a/b/c/foo.txt it would create every folder and sub-folder here a, b and c until it reaches the last folder to create foo.txt, In-this case I noticed that there's no validation at all on the amount of folders being created, that said we're actually able to CPU and memory consume the system running node-tar and even crash the nodejs client within few seconds of running it using a path with too many sub-folders inside

Steps To Reproduce:

You can reproduce this issue by downloading the tar file I provided in the resources and using node-tar to extract it, you should get the same behavior as the video

Proof Of Concept:

Here's a video show-casing the exploit:

Impact

Denial of service by crashing the nodejs client when attempting to parse a tar archive, make it run out of heap memory and consuming server CPU and memory resources

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language.

Security Fix(es):

• node-tar: denial of service while parsing a tar file due to lack of folders depth validation (CVE-2024-28863)

• nodejs: Bypass network import restriction via data URL (CVE-2024-22020)

Root has patched CVE-2024-28863 in the tar package for Root:npm. Multiple fixed versions available.

node-tar is a Tar for Node.js. node-tar prior to version 6.2.1 has no limit on the number of sub-folders created in the folder creation process. An attacker who generates a large number of sub-folders can consume memory on the system running node-tar and even crash the Node.js client within few seconds of running it using a path with too many sub-folders inside. Version 6.2.1 fixes this issue by preventing extraction in excessively deep sub-folders.
