Detailsinfo

A vulnerability classified as critical was found in Node.js 6.x (JavaScript Library). This vulnerability affects an unknown code block of the component DNS Handler. The manipulation with an unknown input leads to a 7pk security vulnerability (DNS Rebinding). The CWE definition for the vulnerability is CWE-254. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The Node.js inspector, in 6.x and later is vulnerable to a DNS rebinding attack which could be exploited to perform remote code execution. An attack is possible from malicious websites open in a web browser on the same computer, or another computer with network access to the computer running the Node.js process. A malicious website could use a DNS rebinding attack to trick the web browser to bypass same-origin-policy checks and to allow HTTP connections to localhost or to hosts on the local network. If a Node.js process with the debug port active is running on localhost or on a host on the local network, the malicious website could connect to it as a debugger, and get full code execution access.

The bug was discovered 03/21/2018. The weakness was disclosed 05/17/2018 (Website). The advisory is shared for download at nodejs.org. This vulnerability was named CVE-2018-7160 since 02/15/2018. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1211.

The vulnerability was handled as a non-public zero-day exploit for at least 7 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 108738 (FreeBSD : node.js -- multiple vulnerabilities (5a9bbb6e-32d3-11e8-a769-6daaba161086)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l.
