CVE-2016-10536
5.9 · MEDIUMOverview
CVE-2016-10536 is a medium-severity vulnerability affecting socket engine.io-client. It was published on May 31, 2018 and has a CVSS 3.0 base score of 5.9 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 5.9, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
engine.io-client is the client for engine.io, the implementation of a transport-based cross-browser/cross-device bi-directional communication layer for Socket.IO. The vulnerability is related to the way that node.js handles the `rejectUnauthorized` setting. If the value is something that evaluates to false, certificate verification will be disabled. This is problematic as engine.io-client 1.6.8 and earlier passes in an object for settings that includes the rejectUnauthorized property, whether it has been set or not. If the value has not been explicitly changed, it will be passed in as `null`, resulting in certificate verification being turned off.
Remediation
Check the references section for vendor advisories and patches from socket. Update engine.io-client to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
