The following versions were EOL at the time the CVE was created but are known to be affected: from 1.1.23 through 1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected. Apache Tomcat Native users are recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue. Apache Tomcat users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which fix the issue.

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-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-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-2025-0501 2026-04-15 7.5 High
An issue in the native clients for Amazon WorkSpaces (when running PCoIP protocol) may allow an attacker to access remote sessions via man-in-the-middle.
CVE-2025-30000 2026-04-15 6.7 Medium
A vulnerability has been identified in Siemens License Server (SLS) (All versions < V4.3). The affected application does not properly restrict permissions of the users. This could allow a lowly-privileged attacker to escalate their privileges.
CVE-2025-32057 1 Bosch 1 Infotainment System Ecu 2026-04-15 6.5 Medium
The Infotainment ECU manufactured by Bosch which is installed in Nissan Leaf ZE1 – 2020 uses a Redbend service for over-the-air provisioning and updates. HTTPS is used for communication with the back-end server. Due to usage of the default configuration for the underlying SSL engine, the server root certificate is not verified. As a result, an attacker may be able to impersonate a Redbend backend server using a self-signed certificate. First identified on Nissan Leaf ZE1 manufactured in 2020.
