CVE-2002-0862 2 Apple, Microsoft 10 Macos, Internet Explorer, Office and 7 more 2026-04-16 N/A
The (1) CertGetCertificateChain, (2) CertVerifyCertificateChainPolicy, and (3) WinVerifyTrust APIs within the CryptoAPI for Microsoft products including Microsoft Windows 98 through XP, Office for Mac, Internet Explorer for Mac, and Outlook Express for Mac, do not properly verify the Basic Constraints of intermediate CA-signed X.509 certificates, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack for SSL sessions, as originally reported for Internet Explorer and IIS.
CVE-2005-3170 1 Microsoft 1 Windows 2000 2026-04-16 5 Medium
The LDAP client on Microsoft Windows 2000 before Update Rollup 1 for SP4 accepts certificates using LDAP Secure Sockets Layer (LDAPS) even when the Certificate Authority (CA) is not trusted, which could allow attackers to trick users into believing that they are accessing a trusted site.
CVE-2003-1229 2 Oracle, Sun 3 Jre, Java Web Start, Jsse 2026-04-16 N/A
X509TrustManager in (1) Java Secure Socket Extension (JSSE) in SDK and JRE 1.4.0 through 1.4.0_01, (2) JSSE before 1.0.3, (3) Java Plug-in SDK and JRE 1.3.0 through 1.4.1, and (4) Java Web Start 1.0 through 1.2 incorrectly calls the isClientTrusted method when determining server trust, which results in improper validation of digital certificate and allows remote attackers to (1) falsely authenticate peers for SSL or (2) incorrectly validate signed JAR files.
CVE-2019-12098 4 Debian, Fedoraproject, Heimdal Project and 1 more 5 Debian Linux, Fedora, Heimdal and 2 more 2026-04-15 7.4 High
In the client side of Heimdal before 7.6.0, failure to verify anonymous PKINIT PA-PKINIT-KX key exchange permits a man-in-the-middle attack. This issue is in krb5_init_creds_step in lib/krb5/init_creds_pw.c.
CVE-2026-21228 1 Microsoft 1 Azure Local 2026-04-15 8.1 High
Improper certificate validation in Azure Local allows an unauthorized attacker to execute code over a network.
CVE-2026-35560 4 Amazon, Apple, Linux and 1 more 5 Amazon Athena Odbc Driver, Athena Odbc, Macos and 2 more 2026-04-15 7.4 High
Improper certificate validation in the identity provider connection components in Amazon Athena ODBC driver before 2.1.0.0 might allow a man-in-the-middle threat actor to intercept authentication credentials due to insufficient default transport security when connecting to identity providers. This only applies to connections with external identity providers and does not apply to connections with Athena. To remediate this issue, users should upgrade to version 2.1.0.0.
CVE-2024-9160 2026-04-15 N/A
In versions of the PEADM Forge Module prior to 3.24.0 a security misconfiguration was discovered.
CVE-2024-7383 1 Redhat 2 Advanced Virtualization, Enterprise Linux 2026-04-15 7.4 High
A flaw was found in libnbd. The client did not always correctly verify the NBD server's certificate when using TLS to connect to an NBD server. This issue allows a man-in-the-middle attack on NBD traffic.
CVE-2024-48915 1 Astroxnetwork 1 Agent Dart 2026-04-15 N/A
Agent Dart is an agent library built for Internet Computer for Dart and Flutter apps. Prior to version 1.0.0-dev.29, certificate verification in `lib/agent/certificate.dart` does not occur properly. During the delegation verification in the `_checkDelegation` function, the canister_ranges aren't verified. The impact of not checking the canister_ranges is that a subnet can sign canister responses in behalf of another subnet. The certificate’s timestamp, i.e /time path, is also not verified, meaning that the certificate effectively has no expiration time. Version 1.0.0-dev.29 implements appropriate certificate verification.
CVE-2024-47258 2026-04-15 8.1 High
2N Access Commander version 2.1 and prior is vulnerable in default settings to Man In The Middle attack due to not verifying certificates of 2N edge devices. 2N has currently released an updated version 3.3 of 2N Access Commander, with added Certificate Fingerprint Verification. Since version 2.2 of 2N Access Commander (released in February 2022) it is also possible to enforce TLS certificate validation.It is recommended that all customers update 2N Access Commander to the latest version and use one of two mentioned practices.
