In this configuration, attackers could impersonate other users or exploit the client-server protocol without being authenticated.

Netbus 1.5 through 1.7 allows more than one client to be connected at the same time, but only prompts the first connection for authentication, which allows remote attackers to gain access.

Session fixation vulnerability in moziloCMS 1.10.2 and earlier allows remote attackers to hijack web sessions by setting the PHPSESSID parameter.

login_ldap 3.1 and 3.2 allows remote attackers to initiate unauthenticated bind requests if (1) bind_anon_dn is on, which allows a bind with no password provided, (2) bind_anon_cred is on, which allows a bind with no DN, or (3) bind_anon is on, which allows a bind with no DN or password.

The time-based one-time-password (TOTP) function in the application logic of the Green Electronics RainMachine Mini-8 (2nd generation) uses the administrator's password hash to generate a 6-digit temporary passcode that can be used for remote and local access, aka a "Use of Password Hash Instead of Password for Authentication" issue. This is exploitable by an attacker who discovers a hash value in the rainmachine-settings.sqlite file.

Imperva SecureSphere gateway (GW) running v13, for both pre-First Time Login or post-First Time Login (FTL), if the attacker knows the basic authentication passwords, the GW may be vulnerable to RCE through specially crafted requests, from the web access management interface.

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). Prior to version 2.7.0, server side authentication against a `SAM` file might be successful for invalid credentials if the server has configured an invalid `SAM` file path. FreeRDP based clients are not affected. RDP server implementations using FreeRDP to authenticate against a `SAM` file are affected. Version 2.7.0 contains a fix for this issue. As a workaround, use custom authentication via `HashCallback` and/or ensure the `SAM` database path configured is valid and the application has file handles left.

The TIBCO Spotfire authentication component of TIBCO Software Inc.'s TIBCO Spotfire Analytics Platform for AWS Marketplace, and TIBCO Spotfire Server contains a vulnerability in the handling of the authentication that theoretically may allow an attacker to gain full access to a target account, independent of configured authentication mechanisms.

When MISP before 2.4.80 is configured with X.509 certificate authentication (CertAuth) in conjunction with a non-MISP external user management ReST API, if an external user provides X.509 certificate authentication and this API returns an empty value, the unauthenticated user can be granted access as an arbitrary user.

A vulnerability in the Common Access Card (CAC) authentication feature of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to bypass authentication and access the FMC system. The attacker must have a valid CAC to initiate the access attempt. The vulnerability is due to incorrect session invalidation during CAC authentication. An attacker could exploit this vulnerability by performing a CAC-based authentication attempt to an affected system. A successful exploit could allow the attacker to access an affected system with the privileges of a CAC-authenticated user who is currently logged in.

A vulnerability in the Kerberos authentication feature of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to impersonate the Kerberos key distribution center (KDC) and bypass authentication on an affected device that is configured to perform Kerberos authentication for VPN or local device access. The vulnerability is due to insufficient identity verification of the KDC when a successful authentication response is received. An attacker could exploit this vulnerability by spoofing the KDC server response to the ASA device. This malicious response would not have been authenticated by the KDC. A successful attack could allow an attacker to bypass Kerberos authentication.

MaLion for Windows 5.2.1 and earlier (only when "Remote Control" is installed) and MaLion for Mac 4.0.1 to 5.2.1 (only when "Remote Control" is installed) allow remote attackers to bypass authentication to execute arbitrary commands or operations on Terminal Agent.

Verizon 5G Home LVSKIHP outside devices through 2022-02-15 allow anyone (knowing the device's serial number) to access a CPE admin website, e.g., at the 10.0.0.1 IP address. The password (for the verizon username) is calculated by concatenating the serial number and the model (i.e., the LVSKIHP string), running the sha256sum program, and extracting the first seven characters concatenated with the last seven characters of that SHA-256 value.

Nextcloud Server before 9.0.54 and 10.0.1 & ownCloud Server before 9.1.2, 9.0.6, and 8.2.9 suffer from SMB User Authentication Bypass. Nextcloud/ownCloud include an optional and not by default enabled SMB authentication component that allows authenticating users against an SMB server. This backend is implemented in a way that tries to connect to a SMB server and if that succeeded consider the user logged-in. The backend did not properly take into account SMB servers that have any kind of anonymous auth configured. This is the default on SMB servers nowadays and allows an unauthenticated attacker to gain access to an account without valid credentials. Note: The SMB backend is disabled by default and requires manual configuration in the Nextcloud/ownCloud config file. If you have not configured the SMB backend then you're not affected by this vulnerability.

The Google Authenticator login (ga_login) module 7.x before 7.x-1.3 for Drupal, when multi-factor authentication is enabled, allows remote attackers to bypass authentication for accounts without an associated Google Authenticator token by logging in with the username.

Tenda AC18 Router through V15.03.05.05_EN and through V15.03.05.19(6318) CN devices could cause a remote code execution due to incorrect authentication handling of vulnerable logincheck() function in /usr/lib/lua/ngx_authserver/ngx_wdas.lua file if the administrator UI Interface is set to "radius".
