dotnet: .NET Information Disclosure Vulnerability

A flaw exists in certain .NET builds where a man-in-the-middle MITM attacker can prevent or downgrade TLS between a client and an SMTP server. This may cause the client to send credentials or message data over an unencrypted connection, exposing sensitive information to the attacker...

CVE-2025-59270 psPAS does not enforce TLS 1.2 within Get-PASSAMLResponse

psPAS PowerShell module does not explicitly enforce TLS 1.2 within the 'Get-PASSAMLResponse' function during the SAML authentication process. An unauthenticated attacker in a 'Man-in-the-Middle' position could manipulate the TLS handshake and downgrade TLS to a deprecated protocol. Fixed in 7.0.2...

TLS Downgrade Attack

github.com/refraction-networking/utls is vulnerable to TLS Downgrade Attack. The vulnerability is due to missing downgrade protection caused due to failure to implement and verify the downgrade canary in TLS 1.3 handshakes when using a custom ClientHello spec, allowing an attacker to force a...

Protection Mechanism Failure

Overview Affected versions of this package are vulnerable to Protection Mechanism Failure in the ClientHandshake function, which handles ClientHello messages, and in particular the serverHello.random field. An attacker can downgrade the TLS connection from TLS 1.3 by removing the SupportedVersion...

GHSA-PMC3-P9HX-JQ96 uTLS ServerHellos are accepted without checking TLS 1.3 downgrade canaries

Description Before version 1.7.0, utls did not implement the TLS 1.3 downgrade protection mechanism specified in RFC 8446 Section 4.1.3 when using a utls ClientHello spec. This allowed an active network adversary to downgrade TLS 1.3 connections initiated by a utls client to a lower TLS version...

CVE-2024-5814

A malicious TLS1.2 server can force a TLS1.3 client with downgrade capability to use a ciphersuite that it did not agree to and achieve a successful connection. This is because, aside from the extensions, the client was skipping fully parsing the server hello...

CVE-2024-5814

CVE-2024-5814 is confirmed in the NVD entry and echoed by other connected advisories describing a downgrade flaw where a malicious TLS1.2 server can force a TLS1.3 client with downgrade capability to use a cipher-suite it did not agree to, due to the client skipping full parsing of the ServerHell...

DEBIAN-CVE-2024-28755

An issue was discovered in Mbed TLS 3.5.x before 3.6.0. When an SSL context was reset with the mbedtlssslsessionreset API, the maximum TLS version to be negotiated was not restored to the configured one. An attacker was able to prevent an Mbed TLS server from establishing any TLS 1.3 connection,...

Weak TLS Encryption

MeshCentral is vulnerable to TLS Downgrade Attack. The vulnerability is due to the usage of TLS that includes known vulnerabilities. An attacker can possibly eavesdrop on communication as result of this vulnerability...

SUSE CVE-2018-16868

A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade...

ruby: StartTLS stripping vulnerability in Net::IMAP

Ruby's Net::IMAP module did not raise an exception when receiving an unexpected response to the STARTTLS command and the connection was not upgraded to use TLS. A man-in-the-middle attacker could use this flaw to prevent Ruby applications using Net::IMAP to enable TLS encryption for a connection ...
