CVE-2023-3724

This CVE (CVE-2023-3724) describes a TLS 1.3 client-side issue where, if a server is malicious and the client sends neither a PSK nor a KSE, a default, potentially known, IKM buffer is used to generate the session master secret. The root cause is a mishandled IKM when PSK/KSE are absent, which ca...

CVE-2023-3724 TLS 1.3 client issue handling malicious server when not including a KSE and PSK extension

If a TLS 1.3 client gets neither a PSK pre shared key extension nor a KSE key share extension when connecting to a malicious server, a default predictable buffer gets used for the IKM Input Keying Material value when generating the session master secret. Using a potentially known IKM value when...

Siemens SCALANCE W1750D Cryptographic Issues (CVE-2017-13099)

wolfSSL prior to version 3.12.2 provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private key from a vulnerable wolfSSL application. This vulnerability is referred to as ROBOT. This plugin only works with Tenable.ot...

K15622: wolfSSL CyaSSL vulnerability CVE-2013-1623

Security Advisory Description The TLS and DTLS implementations in wolfSSL CyaSSL before 2.5.0 do not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks...

wolfSSL 5.3.0 Denial Of Service Vulnerability

In wolfSSL version 5.3.0, man-in-the-middle attackers or a malicious server can crash TLS 1.2 clients during a handshake. If an attacker injects a large ticket above 256 bytes into a NewSessionTicket message in a TLS 1.2 handshake, and the client has a non-empty session cache, the session cache...

wolfSSL 5.5.0 Session Resumption Denial Of Service Vulnerability

wolfSSL versions prior to 5.5.0 suffer from a denial of service condition related to session resumption. When a TLS 1.3 client connects to a wolfSSL server and SSLclear is called on its session, the server crashes with a segmentation fault. The bug occurs after a client performs a handshake again...
