CVSS v3.1 |
| An Improper Certificate Validation vulnerability in the OPC-UA client and ANSL over TLS client used in Automation Studio versions before 6.5 could allow an unauthenticated attacker on the network to position themselves to intercept and interfere with data exchanges. |
| A vulnerability was reported in the Lenovo Scanner pro application during an internal security assessment that, under certain circumstances, could allow an attacker on the same logical network to disclose sensitive user files from the application. |
| A certificate verification error in wolfSSL when building with the WOLFSSL_SYS_CA_CERTS and WOLFSSL_APPLE_NATIVE_CERT_VALIDATION options results in the wolfSSL
client failing to properly verify the server certificate's domain name,
allowing any certificate issued by a trusted CA to be accepted regardless of the hostname. |
| Improper Certificate Validation (CWE-295) in the Controller 7000 OneLink implementation could allow an unprivileged attacker to perform a limited denial of service or perform privileged overrides during the initial configuration of the Controller, there is no risk for Controllers once they are connected.
This issue affects Controller 7000:
9.30 prior to vCR9.30.250624a (distributed in 9.30.1871 (MR1)). |
| Improper certificate validation in Logstash's TCP output could lead to a man-in-the-middle (MitM) attack in “client” mode, as hostname verification in TCP output was not being performed when the ssl_verification_mode => full was set. |
| An Improper Certificate Validation vulnerability exists in Tenable Security Center where an authenticated, privileged attacker could intercept email messages sent from Security Center via a rogue SMTP server. |
| 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. |
| Improper certificate validation vulnerability exists in 'デジラアプリ' App for iOS prior to ver.80.10.00. If this vulnerability is exploited, a man-in-the-middle attack may allow an attacker to eavesdrop on and/or tamper with an encrypted communication. |
| HCL Digital Experience components Ring API and dxclient may be vulnerable to man-in-the-middle (MitM) attacks prior to 9.5 CF226. An attacker could intercept and potentially alter communication between two parties. |
| 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. |
| Multiple MFPs provided by Brother Industries, Ltd. does not properly validate server certificates, which may allow a man-in-the-middle attacker to replace the set of root certificates used by the product with a set of arbitrary certificates. |
| 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. |
| An issue in Eugeny Tabby 1.0.213 allows a remote attacker to obtain sensitive information via the server and sends the SSH username and password even when the host key verification fails. |
| WTW-EAGLE App does not properly validate server certificates, which may allow a man-in-the-middle attacker to monitor encrypted traffic. |
| A vulnerability in the meeting-join functionality of Cisco Webex Meetings could have allowed an unauthenticated, network-proximate attacker to complete a meeting-join process in place of an intended targeted user, provided the requisite conditions were satisfied. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed.
This vulnerability existed due to client certificate validation issues. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by monitoring local wireless or adjacent networks for client-join requests and attempting to interrupt and complete the meeting-join flow as another user who was currently joining a meeting. To successfully exploit the vulnerability, an attacker would need the capability to position themselves in a local wireless or adjacent network, to monitor and intercept the targeted network traffic flows, and to satisfy timing requirements in order to interrupt the meeting-join flow and exploit the vulnerability. A successful exploit could have allowed the attacker to join the meeting as another user. However, the Cisco Product Security Incident Response Team (PSIRT) is not aware of any malicious use of the vulnerability that is described in this advisory. |
| GoSign Desktop through 2.4.1 disables TLS certificate validation when configured to use a proxy server. This can be problematic if the GoSign Desktop user selects an arbitrary proxy server without consideration of whether outbound HTTPS connections from the proxy server to Internet servers succeed even for untrusted or invalid server certificates. In this scenario (which is outside of the product's design objectives), integrity protection could be bypassed. In typical cases of a proxy server for outbound HTTPS traffic from an enterprise, those connections would not succeed. (Admittedly, the usual expectation is that a client application is configured to trust an enterprise CA and does not set SSL_VERIFY_NONE.) Also, it is of course unsafe to place ~/.gosign in the home directory of an untrusted user and then have other users execute downloaded files. |
| In Yealink RPS before 2025-05-26, the certificate upload function does not properly validate certificate content, potentially allowing invalid certificates to be uploaded. |
| An improper certificate validation vulnerability was reported in the Lenovo Universal Device Client (UDC) that could allow a user capable of intercepting network traffic to obtain application metadata, including device information, geolocation, and telemetry data. |
| A vulnerability was reported in the Lenovo LeCloud client application that, under certain conditions, could allow information disclosure. |
| A vulnerability was found in Hualai Xiaofang iSC5 3.2.2_112 and classified as problematic. Affected by this issue is some unknown functionality. The manipulation leads to improper certificate validation. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The identifier of this vulnerability is VDB-261788. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. |
