Detailsinfo

A vulnerability, which was classified as problematic, has been found in Node.js 9.7.x/10.x (JavaScript Library). Affected by this issue is an unknown functionality of the component net.Socket. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability. CVE summarizes:

Node.js versions 9.7.0 and later and 10.x are vulnerable and the severity is MEDIUM. A bug introduced in 9.7.0 increases the memory consumed when reading from the network into JavaScript using the net.Socket object directly as a stream. An attacker could use this cause a denial of service by sending tiny chunks of data in short succession. This vulnerability was restored by reverting to the prior behaviour.

The bug was discovered 06/12/2018. The weakness was published 06/13/2018 (Website). The advisory is shared for download at nodejs.org. This vulnerability is handled as CVE-2018-7164 since 02/15/2018. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1499.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 110539 (FreeBSD : node.js -- multiple vulnerabilities (45b8e2eb-7056-11e8-8fab-63ca6e0e13a2)), 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.

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 days after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (110539) and SecurityFocus (BID 104463†). Similar entries are available at VDB-119538, VDB-119539 and VDB-119541. Once again VulDB remains the best source for vulnerability data.
