CVE-2025-61727 2 Go Standard Library, Golang 2 Crypto Tls, Go 2025-12-18 6.5 Medium
An excluded subdomain constraint in a certificate chain does not restrict the usage of wildcard SANs in the leaf certificate. For example a constraint that excludes the subdomain test.example.com does not prevent a leaf certificate from claiming the SAN *.example.com.
CVE-2025-6032 1 Redhat 3 Enterprise Linux, Openshift, Rhel Eus 2025-11-29 8.3 High
A flaw was found in Podman. The podman machine init command fails to verify the TLS certificate when downloading the VM images from an OCI registry. This issue results in a Man In The Middle attack.
CVE-2024-49369 2 Debian, Icinga 3 Debian Linux, Icinga, Icinga Web 2 2025-11-26 9.8 Critical
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. The TLS certificate validation in all Icinga 2 versions starting from 2.4.0 was flawed, allowing an attacker to impersonate both trusted cluster nodes as well as any API users that use TLS client certificates for authentication (ApiUser objects with the client_cn attribute set). This vulnerability has been fixed in v2.14.3, v2.13.10, v2.12.11, and v2.11.12.
CVE-2025-34199 2 Printerlogic, Vasion 4 Vasion Print, Virtual Appliance, Virtual Appliance Application and 1 more 2025-11-25 8.1 High
Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.1049 and Application versions prior to 20.0.2786 (VA and SaaS deployments) contain insecure defaults and code patterns that disable TLS/SSL certificate verification for communications to printers and internal microservices. In multiple places, the application sets libcurl/PHP transport options such that CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER are effectively disabled, and environment variables (for example API_*_VERIFYSSL=false) are used to turn off verification for gateway and microservice endpoints. As a result, the client accepts TLS connections without validating server certificates (and, in some cases, uses clear-text HTTP), permitting on-path attackers to perform man-in-the-middle (MitM) attacks. An attacker able to intercept network traffic between the product and printers or microservices can eavesdrop on and modify sensitive data (including print jobs, configuration, and authentication tokens), inject malicious payloads, or disrupt service. This vulnerability has been identified by the vendor as: V-2024-024 — Insecure Communication to Printers & Microservices.
CVE-2024-13990 1 Microworld Technologies 1 Escan 2025-11-19 N/A
MicroWorld eScan AV's update mechanism failed to ensure authenticity and integrity of updates: update packages were delivered and accepted without robust cryptographic verification. As a result, an on-path attacker could perform a man-in-the-middle (MitM) attack and substitute malicious update payloads for legitimate ones. The eScan AV client accepted these substituted packages and executed or loaded their components (including sideloaded DLLs and Java/installer payloads), enabling remote code execution on affected systems. MicroWorld eScan confirmed remediation of the update mechanism on 2023-07-31 but versioning details are unavailable. NOTE: MicroWorld eScan disputes the characterization in third-party reports, stating the issue relates to 2018–2019 and that controls were implemented then.
CVE-2025-34235 2 Microsoft, Vasion 3 Windows, Virtual Appliance Application, Virtual Appliance Host 2025-11-17 7.8 High
Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.1.102 and Application prior to version 25.1.1413 (Windows client deployments) contain a registry key that can be enabled by administrators, causing the client to skip SSL/TLS certificate validation. An attacker who can intercept HTTPS traffic can then inject malicious driver DLLs, resulting in remote code execution with SYSTEM privileges; a local attacker can achieve local privilege escalation via a junction‑point DLL injection. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.
CVE-2025-9708 1 Kubernetes 1 Kubernetes 2025-11-04 6.8 Medium
A vulnerability exists in the Kubernetes C# client where the certificate validation logic accepts properly constructed certificates from any Certificate Authority (CA) without properly verifying the trust chain. This flaw allows a malicious actor to present a forged certificate and potentially intercept or manipulate communication with the Kubernetes API server, leading to possible man-in-the-middle attacks and API impersonation.
CVE-2025-0239 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-03 4 Medium
When using Alt-Svc, ALPN did not properly validate certificates when the original server is redirecting to an insecure site. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Thunderbird < 134, and Thunderbird < 128.6.
CVE-2023-31484 3 Cpanpm Project, Perl, Redhat 3 Cpanpm, Perl, Enterprise Linux 2025-11-03 8.1 High
CPAN.pm before 2.35 does not verify TLS certificates when downloading distributions over HTTPS.
CVE-2025-10548 1 Clevercontrol 1 Clevercontrol 2025-11-03 6.5 Medium
The CleverControl employee monitoring software (v11.5.1041.6) fails to validate TLS server certificates during the installation process. The installer downloads and executes external components using curl.exe --insecure, enabling a man-in-the-middle attacker to deliver malicious files that are executed with SYSTEM privileges. This can lead to full remote code execution with administrative rights. No patch is available as the vendor has been unresponsive. It is assumed that previous versions are also affected, but this is not confirmed.
CVE-2022-26923 1 Microsoft 20 Windows 10 1507, Windows 10 1607, Windows 10 1809 and 17 more 2025-10-30 8.8 High
Active Directory Domain Services Elevation of Privilege Vulnerability
CVE-2025-6433 1 Mozilla 1 Firefox 2025-10-30 9.8 Critical
If a user visited a webpage with an invalid TLS certificate, and granted an exception, the webpage was able to provide a WebAuthn challenge that the user would be prompted to complete. This is in violation of the WebAuthN spec which requires "a secure transport established without errors". This vulnerability affects Firefox < 140 and Thunderbird < 140.
CVE-2025-46551 1 Jruby 2 Jruby, Jruby-openssl 2025-10-21 3.7 Low
JRuby-OpenSSL is an add-on gem for JRuby that emulates the Ruby OpenSSL native library. Starting in JRuby-OpenSSL version 0.12.1 and prior to version 0.15.4 (corresponding to JRuby versions starting in 9.3.4.0 prior to 9.4.12.1 and 10.0.0.0 prior to 10.0.0.1), when verifying SSL certificates, JRuby-OpenSSL does not verify that the hostname presented in the certificate matches the one the user tries to connect to. This means a man-in-the-middle could just present any valid cert for a completely different domain they own, and JRuby would accept the cert. Anybody using JRuby to make requests of external APIs, or scraping the web, that depends on https to connect securely. JRuby-OpenSSL version 0.15.4 contains a fix for the issue. This fix is included in JRuby versions 10.0.0.1 and 9.4.12.1.
CVE-2025-50944 1 Avtech 1 Eagleeyes\(lite\) 2025-10-14 8.8 High
An issue was discovered in the method push.lite.avtech.com.MySSLSocketFactoryNew.checkServerTrusted in AVTECH EagleEyes 2.0.0. The custom X509TrustManager used in checkServerTrusted only checks the certificate's expiration date, skipping proper TLS chain validation.
CVE-2025-5279 2025-10-14 7.5 High
When the Amazon Redshift Python Connector is configured with the BrowserAzureOAuth2CredentialsProvider plugin, the driver skips the SSL certificate validation step for the Identity Provider.
