Synapse is a Matrix protocol homeserver written in Python with the Twisted framework. In affected versions it may be possible for a deactivated user to login when using uncommon configurations. This only applies if any of the following are true: 1. JSON Web Tokens are enabled for login via the `jwt_config.enabled` configuration setting. 2. The local password database is enabled via the `password_config.enabled` and `password_config.localdb_enabled` configuration settings *and* a user's password is updated via an admin API after a user is deactivated. Note that the local password database is enabled by default, but it is uncommon to set a user's password after they've been deactivated. Installations that are configured to only allow login via Single Sign-On (SSO) via CAS, SAML or OpenID Connect (OIDC); or via an external password provider (e.g. LDAP) are not affected. If not using JSON Web Tokens, ensure that deactivated users do not have a password set. This issue has been addressed in version 1.85.0. Users are advised to upgrade.Show less

Insufficient authentication in the MQTT backend (broker) allows an attacker to access and even manipulate the telemetry data of the entire fleet of vehicles using the HopeChart HQT-401 telematics unit. Other models are possibly affected too. Multiple vulnerabilities were identified: - The MQTT backend does not require authentication, allowing unauthorized connections from an attacker. - The vehicles publish their telemetry data (e.g. GPS Location, speed, odometer, fuel, etc) as messages in public topics. The backend also sends commands to the vehicles as MQTT posts in public topics. As a result, an attacker can access the confidential data of the entire fleet that is managed by the backend. - The MQTT messages sent by the vehicles or the backend are not encrypted or authenticated. An attacker can create and post messages to impersonate a vehicle or the backend. The attacker could then, for example, send incorrect information to the backend about the vehicle's location. - The backend can inject data into a vehicle´s CAN bus by sending a specific MQTT message on a public topic. Because these messages are not authenticated or encrypted, an attacker could impersonate the backend, create a fake message and inject CAN data in any vehicle managed by the backend. The confirmed version is 201808021036, however further versions have been also identified as potentially impacted. Show less

A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.Show less

Teltonika’s Remote Management System versions 4.14.0 is vulnerable to an unauthorized attacker registering previously unregistered devices through the RMS platform. If the user has not disabled the "RMS management feature" enabled by default, then an attacker could register that device to themselves. This could enable the attacker to perform different operations on the user's devices, including remote code execution with 'root' privileges (using the 'Task Manager' feature on RMS). Show less

Teltonika’s Remote Management System versions prior to 4.10.0 use device serial numbers and MAC addresses to identify devices from the user perspective for device claiming and from the device perspective for authentication. If an attacker obtained the serial number and MAC address of a device, they could authenticate as that device and steal communication credentials of the device. This could allow an attacker to enable arbitrary command execution as root by utilizing management options within the newly registered devices. Show less

The OTP Login Woocommerce & Gravity Forms plugin for WordPress is vulnerable to authentication bypass. This is due to the fact that when generating OTP codes for users to use in order to login via phone number, the plugin returns these codes in an AJAX response. This makes it possible for unauthenticated attackers to obtain login codes for administrators. This does require an attacker have access to the phone number configured for an account, which can be obtained via social engineering or reconnaissance.Show less
