• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 7.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-20

Description

All versions of Node.js 8.x, 9.x, and 10.x are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node server providing an http2 server to crash. This can be accomplished by interacting with the http2 server in a manner that triggers a cleanup bug where objects are used in native code after they are no longer available. This has been addressed by updating the http2 implementation.

Affected products

• Node.js: from 8.0.0 through 8.8.1; from 8.9.0 before 8.11.3; from 9.0.0 before 9.11.2; from 10.0.0 before 10.4.1 — fixed in 10.4.1, 8.11.3, 9.11.2

How to fix

Upgrade to a fixed version: Node.js 10.4.1, 8.11.3, 9.11.2. Check the vendor advisory for mitigations.
