Loxone Miniserver devices with firmware before 11.1 (aka 11.1.9.3) are unable to use an authentication method that is based on the "signature of the update package." Therefore, these devices (or attackers who are spoofing these devices) can continue to use an unauthenticated cloud service for an indeterminate time period (possibly forever). Once an individual device's firmware is updated, and authentication occurs once, the cloud service recategorizes the device so that authentication is subsequently always required, and spoofing cannot occur.

Affected Products and Versions * Apache Druid * Affected Versions: 0.17.0 through 35.x (all versions prior to 36.0.0) * Prerequisites: * druid-basic-security extension enabled * LDAP authenticator configured * Underlying LDAP server permits anonymous bind                                                                                                                                                    Vulnerability Description An authentication bypass vulnerability exists in Apache Druid when using the druid-basic-security extension with LDAP authentication. If the underlying LDAP server is configured to allow anonymous binds, an attacker can bypass authentication by providing an existing username with an empty password. This allows unauthorized access to otherwise restricted Druid resources without valid credentials. The vulnerability stems from improper validation of LDAP authentication responses when anonymous binds are permitted, effectively treating anonymous bind success as valid user authentication. Impact A remote, unauthenticated attacker can: * Gain unauthorized access to the Apache Druid cluster * Access sensitive data stored in Druid datasources * Execute queries and potentially manipulate data * Access administrative interfaces if the bypassed account has elevated privileges * Completely compromise the confidentiality, integrity, and availability of the Druid deployment                                                                                                                                                                                     Mitigation   Immediate Mitigation (No Druid Upgrade Required):                                                                                                                                                   * Disable anonymous bind on your LDAP server. This prevents the vulnerability from being exploitable and is the recommended immediate action. Resolution * Upgrade Apache Druid to version 36.0.0 or later, which includes fixes to properly reject anonymous LDAP bind attempts.

It is possible to enumerate access card credentials via an unauthenticated network connection to the server in versions of Command Centre v8.20 prior to v8.20.1166(MR3), versions of 8.10 prior to v8.10.1211(MR5), versions of 8.00 prior to v8.00.1228(MR6), all versions of 7.90 and earlier. These credentials can then be used to encode low security cards to be used by the system where insecure card technologies are supported.

A vulnerability has been identified in SIMATIC HMI Unified Comfort Panels (All versions <= V16). Affected devices insufficiently validate authentication attempts as the information given can be truncated to match only a set number of characters versus the whole provided string. This could allow a remote attacker to discover user passwords and obtain access to the Sm@rt Server via a brute-force attack.

METIS WIC devices (versions <= oscore 2.1.234-r18) expose a web-based shell at the /console endpoint that does not require authentication. Accessing this endpoint allows a remote attacker to execute arbitrary operating system commands with root (UID 0) privileges. This results in full system compromise, allowing unauthorized access to modify system configuration, read sensitive data, or disrupt device operations

An issue was discovered on Mofi Network MOFI4500-4GXeLTE 4.1.5-std devices. The authentication function contains undocumented code that provides the ability to authenticate as root without knowing the actual root password. An adversary with the private key can remotely authenticate to the management interface as root.

A security flaw has been discovered in code-projects Contact Management System 1.0. This affects an unknown part of the component CRUD Endpoint. The manipulation of the argument ID results in improper authentication. The attack may be launched remotely.

Authentication Bypass Using an Alternate Path or Channel in temi Robox OS prior to120, temi Android app up to 1.3.7931 allows remote attackers to gain elevated privileges on the temi and have it automatically answer the attacker's calls, granting audio, video, and motor control via unspecified vectors.

iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches.

The Limit Login Attempts plugin before 1.7.1 for WordPress does not clear auth cookies upon a lockout, which might make it easier for remote attackers to conduct brute-force authentication attempts.

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In versions up to and including 1.5.0, the application checks the validity of the username but appears to skip, misinterpret, or incorrectly validate the password when the provided username matches a known system service account. The application's login function fails to properly handle the password validation result for these users, effectively granting authenticated access to anyone who knows one of these common usernames and provides any password. As of time of publication, no known patched versions are available.

Schneider Electric Modicon Quantum PLC does not perform authentication between the Unity software and PLC, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via unspecified vectors.

Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. In versions of Onedev prior to 7.3.0 unauthenticated users can take over a OneDev instance if there is no properly configured reverse proxy. The /git-prereceive-callback endpoint is used by the pre-receive git hook on the server to check for branch protections during a push event. It is only intended to be accessed from localhost, but the check relies on the X-Forwarded-For header. Invoking this endpoint leads to the execution of one of various git commands. The environment variables of this command execution can be controlled via query parameters. This allows attackers to write to arbitrary files, which can in turn lead to the execution of arbitrary code. Such an attack would be very hard to detect, which increases the potential impact even more. Users are advised to upgrade. There are no known workarounds for this issue.
