CVE-2024-28863 | node-tar vulnerable to denial of service while parsing a tar file due to lack of folders count validation

Exp

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.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
