Node.js up to 0.10.41/0.12.9/4.2.x/5.5.x HTTP Header Parser UTF-8 Encoding input validation

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Node.js up to 0.10.41/0.12.9/4.2.x/5.5.x (JavaScript Library) and classified as critical. This issue affects an unknown part of the component HTTP Header Parser. The manipulation as part of a UTF-8 Encoding leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The HTTP header parsing code in Node.js 0.10.x before 0.10.42, 0.11.6 through 0.11.16, 0.12.x before 0.12.10, 4.x before 4.3.0, and 5.x before 5.6.0 allows remote attackers to bypass an HTTP response-splitting protection mechanism via UTF-8 encoded Unicode characters in the HTTP header, as demonstrated by %c4%8d%c4%8a.

The weakness was disclosed 04/07/2016 by Amit Klein (Website). It is possible to read the advisory at lists.fedoraproject.org. The identification of this vulnerability is CVE-2016-2216 since 02/03/2016. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 89508 (Fedora 23 : nodejs-0.10.42-4.fc23 (2016-3102c11757)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 168737 (OpenSuSE Security Update for Security nodejs (openSUSE-SU-2016:0604-1)).

Upgrading to version 0.10.42, 0.12.10, 4.3.0 or 5.6.0 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (89508), SecurityFocus (BID 83141†) and Vulnerability Center (SBV-58061†). The entries VDB-81704, VDB-93152 and VDB-93153 are pretty similar. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
