CVSS v3.1 |
| Instead of typical session tokens or cookies, it is verified on a per-request basis if the originating IP address has once successfully logged in. As soon as an authentication request from a certain source IP is successful, the IP address is handled as authenticated. No other session information is stored. Therefore, it is possible to spoof the IP address of a logged-in user to gain access to the Access Manager web interface. |
| 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. |
| The MQTT add-on of PcVue fails to verify that a remote device’s certificate has not already expired or has not yet become valid. This allows malicious devices to present certificates that are not rejected properly.
The use of a client certificate reduces the risk for random devices to take advantage of this flaw. |
| 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. |
| PaperCut Print Deploy is an optional component that integrates with PaperCut NG/MF which simplifies printer deployment and management. When the component is deployed to an environment, the customer has an option to configure the system to use a self-signed certificate. If the customer does not fully configure the system to leverage the trust database on the clients, it opens up the communication between clients and the server to man-in-the-middle attacks.
It was discovered that certain parts of the documentation related to the configuration of SSL in Print Deploy were lacking, which could potentially contribute to a misconfiguration of the Print Deploy client installation. PaperCut strongly recommends to use valid certificates to secure installations and to follow the updated documentation to ensure the correct SSL configuration. Those who use private CAs and/or self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of their operating system and to the Java key store |
| 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. |
| A weakness identified in OpenText Advanced Authentication where a Malicious browser plugin can record and replay the user authentication process to bypass Authentication. This issue affects Advanced Authentication on or before 6.5.0. |
| 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. |
| A malicious client can bypass the client certificate trust check of an opc.https server when the server endpoint is configured to allow only secure communication. |
| Incorrect validation of OCSP certificates vulnerability in TheGreenBow VPN, versions 7.5 and 7.6. During the IKEv2 authentication step, the OCSP-enabled VPN client establishes the tunnel even if it does not receive an OCSP response or if the OCSP response signature is invalid. |
| Bypass vulnerability in the authentication method in the GTT Tax Information System application, related to the Active Directory (LDAP) login method.
Authentication is performed through a local WebSocket, but the web application does not properly validate the authenticity or origin of the data received, allowing an attacker with access to the local machine or internal network to impersonate the legitimate WebSocket and inject manipulated information.
Exploiting this vulnerability could allow an attacker to authenticate as any user in the domain, without the need for valid credentials, compromising the confidentiality, integrity, and availability of the application and its data. |
| SMB forced authentication vulnerability in versions prior to 2025.35.000 of Sage 200 Spain. This vulnerability allows an authenticated attacker with administrator privileges to obtain NTLMv2-SSP Hash by changing any of the paths to a UNC path pointing to a server controlled by the attacker. |
| An issue pertaining to CWE-295: Improper Certificate Validation was discovered in Ayms node-To master. The application disables TLS/SSL certificate validation by setting 'rejectUnauthorized': false in TLS socket options |
| An Improper Certificate Validation vulnerability could allow an authenticated malicious actor with access to UniFi Protect Cameras adjacent network to make unsupported changes to the camera system. |
| Vela is a Pipeline Automation (CI/CD) framework built on Linux container technology written in Golang. Prior to versions 0.25.3 and 0.26.3, by spoofing a webhook payload with a specific set of headers and body data, an attacker could transfer ownership of a repository and its repo level secrets to a separate repository. These secrets could be exfiltrated by follow up builds to the repository. Users with an enabled repository with access to repo level CI secrets in Vela are vulnerable to the exploit, and any user with access to the CI instance and the linked source control manager can perform the exploit. Versions 0.25.3 and 0.26.3 fix the issue. No known workarounds are available. |
| On IROAD X5 devices, a Bypass of Device Pairing can occur via MAC Address Spoofing. The dashcam's pairing mechanism relies solely on MAC address verification, allowing an attacker to bypass authentication by spoofing an already-paired MAC address that can be captured via an ARP scan. |
| 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. |
| Issue summary: Clients using RFC7250 Raw Public Keys (RPKs) to authenticate a
server may fail to notice that the server was not authenticated, because
handshakes don't abort as expected when the SSL_VERIFY_PEER verification mode
is set.
Impact summary: TLS and DTLS connections using raw public keys may be
vulnerable to man-in-middle attacks when server authentication failure is not
detected by clients.
RPKs are disabled by default in both TLS clients and TLS servers. The issue
only arises when TLS clients explicitly enable RPK use by the server, and the
server, likewise, enables sending of an RPK instead of an X.509 certificate
chain. The affected clients are those that then rely on the handshake to
fail when the server's RPK fails to match one of the expected public keys,
by setting the verification mode to SSL_VERIFY_PEER.
Clients that enable server-side raw public keys can still find out that raw
public key verification failed by calling SSL_get_verify_result(), and those
that do, and take appropriate action, are not affected. This issue was
introduced in the initial implementation of RPK support in OpenSSL 3.2.
The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. |
| fast-jwt provides fast JSON Web Token (JWT) implementation. Prior to 5.0.6, the fast-jwt library does not properly validate the iss claim based on the RFC 7519. The iss (issuer) claim validation within the fast-jwt library permits an array of strings as a valid iss value. This design flaw enables a potential attack where a malicious actor crafts a JWT with an iss claim structured as ['https://attacker-domain/', 'https://valid-iss']. Due to the permissive validation, the JWT will be deemed valid. Furthermore, if the application relies on external libraries like get-jwks that do not independently validate the iss claim, the attacker can leverage this vulnerability to forge a JWT that will be accepted by the victim application. Essentially, the attacker can insert their own domain into the iss array, alongside the legitimate issuer, and bypass the intended security checks. This issue is fixed in 5.0.6. |
| An issue was discovered on Alecto IVM-100 2019-11-12 devices. The device uses a custom UDP protocol to start and control video and audio services. The protocol has been partially reverse engineered. Based upon the reverse engineering, no password or username is ever transferred over this protocol. Thus, one can set up the camera connection feed with only the encoded UID. It is possible to set up sessions with the camera over the Internet by using the encoded UID and the custom UDP protocol, because authentication happens at the client side. |
