EUVDB-ID: #VU33814

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-8027

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

Node.js 0.12.x before 0.12.9, 4.x before 4.2.3, and 5.x before 5.1.1 does not ensure the availability of a parser for each HTTP socket, which allows remote attackers to cause a denial of service (uncaughtException and service outage) via a pipelined HTTP request.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Node.js: 0.12.0 - 0.12.8
