Using the ability to perform a Man-in-the-Middle (MITM) attack, which indicates a lack of hostname verification, sensitive account information was able to be intercepted. In this specific scenario, the application's network traffic was intercepted using a proxy server set up in 'transparent' mode while a certificate with an invalid hostname was active. The Android application was found to have hostname verification issues during the server setup and login flows; however, the application did not process requests post-login.

A vulnerability in the Web Services Management Agent (WSMA) feature of Cisco Industrial Network Director (IND) could allow an unauthenticated, remote attacker to gain unauthorized read access to sensitive data using an invalid X.509 certificate. The vulnerability is due to insufficient X.509 certificate validation when establishing a WSMA connection. An attacker could exploit this vulnerability by supplying a crafted X.509 certificate during the WSMA connection setup phase. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on WSMA connections to the affected software. At the time of publication, this vulnerability affected Cisco IND Software releases prior to 1.7.

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. 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. After an SSL connection is initialized via _ustream_ssl_init, and after any data (e.g. the client's HTTP request) is written to the stream using ustream_printf, the code eventually enters the function _ustream_ssl_poll, which is used to dispatch the read/write events
