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.

An issue was discovered in certain Apple products. macOS before 10.12.5 is affected. The issue involves the "802.1X" component. It allows remote attackers to discover the network credentials of arbitrary users by operating a crafted network that requires 802.1X authentication, because EAP-TLS certificate validation mishandles certificate changes.

An exploitable information leak vulnerability exists in the ustream-ssl library of OpenWrt, versions 18.06.4 and 15.05.1. When connecting to a remote server, the server's SSL certificate is checked but no action is taken when the certificate is invalid. An attacker could exploit this behavior by performing a man-in-the-middle attack, providing any certificate, leading to the theft of all the data sent by the client during the first request.An exploitable information leak vulnerability exists in the ustream-ssl library of OpenWrt, versions 18.06.4 and 15.05.1.

In Redgate SQL Monitor 7.1.4 through 10.1.6 (inclusive), the scope for disabling some TLS security certificate checks can extend beyond that defined by various options on the Configuration > Notifications pages to disable certificate checking for alert notifications. These TLS security checks are also ignored during monitoring of VMware machines. This would make SQL Monitor vulnerable to potential man-in-the-middle attacks when sending alert notification emails, posting to Slack or posting to webhooks. The vulnerability is fixed in version 10.1.7.
