When an SRX Series device is configured to use HTTP/HTTPS pass-through authentication services, a client sending authentication credentials in the initial HTTP/HTTPS session is at risk that these credentials may be captured during follow-on HTTP/HTTPS requests by a malicious actor through a man-in-the-middle attack or by authentic servers subverted by malicious actors. FTP, and Telnet pass-through authentication services are not affected. Affected releases are Juniper Networks SRX Series: 12.1X46 versions prior to 12.1X46-D67 on SRX Series; 12.3X48 versions prior to 12.3X48-D25 on SRX Series; 15.1X49 versions prior to 15.1X49-D35 on SRX Series.

This affects all versions of package com.mintegral.msdk:alphab. The Android SDK distributed by the company contains malicious functionality in this module that tracks: 1. Downloads from Google urls either within Google apps or via browser including file downloads, e-mail attachments and Google Docs links. 2. All apk downloads, either organic or not. Mintegral listens to download events in Android's download manager and detects if the downloaded file's url contains: a. google.com or comes from a Google app (the com.android.vending package) b. Ends with .apk for apk downloads In both cases, the module sends the captured data back to Mintegral's servers. Note that the malicious functionality keeps running even if the app is currently not in focus (running in the background).

An issue was discovered in BT CTROMS Terminal OS Port Portal CT-464. Account takeover can occur because the password-reset feature discloses the verification token. Upon a getverificationcode.jsp request, this token is transmitted not only to the registered phone number of the user account, but is also transmitted to the unauthenticated HTTP client.

Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response.

An unintended cleartext issue exists in Go before 1.8.4 and 1.9.x before 1.9.1. RFC 4954 requires that, during SMTP, the PLAIN auth scheme must only be used on network connections secured with TLS. The original implementation of smtp.PlainAuth in Go 1.0 enforced this requirement, and it was documented to do so. In 2013, upstream issue #5184, this was changed so that the server may decide whether PLAIN is acceptable. The result is that if you set up a man-in-the-middle SMTP server that doesn't advertise STARTTLS and does advertise that PLAIN auth is OK, the smtp.PlainAuth implementation sends the username and password.

ikst versions before 1.1.2 download resources over HTTP, which leaves it vulnerable to MITM attacks.

The issue was addressed with improved UI handling. This issue is fixed in iOS 13.3.1 and iPadOS 13.3.1, Safari 13.0.5. A local user may unknowingly send a password unencrypted over the network.
