A vulnerability in the TACACS+ authentication, authorization and accounting (AAA) feature of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an unauthenticated, remote attacker to bypass authentication and log in to an affected device as an administrator. This vulnerability is due to incomplete validation of user-supplied input that is passed to an authentication script. An attacker could exploit this vulnerability by injecting parameters into an authentication request. A successful exploit could allow the attacker to bypass authentication and log in as an administrator to the affected device.

The WooCommerce - Social Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to and including 2.8.7. This is due to the plugin's Apple login handler accepting the Apple id_token and decoding only its base64 payload without verifying the JWT signature against Apple's public keys or validating the issuer, audience, or expiry claims, combined with the security nonce required to invoke the login flow being publicly exposed to unauthenticated users via a localized JavaScript object on the login page. This makes it possible for unauthenticated attackers to log in as any existing WordPress user — including administrators — by supplying a forged id_token whose payload contains the target user's email address, as that email is used without any role exclusion to resolve a WordPress account and immediately issue an authenticated session for it.

DataEase is an open source data visualization analysis tool. Prior to 2.10.4, there is a flaw in the authentication in the io.dataease.auth.filter.TokenFilter class, which can be bypassed and cause the risk of unauthorized access. In the io.dataease.auth.filter.TokenFilter class, ”request.getRequestURI“ is used to obtain the request URL, and it is passed to the "WhitelistUtils.match" method to determine whether the URL request is an interface that does not require authentication. The "match" method filters semicolons, but this is not enough. When users set "server.servlet.context-path" when deploying products, there is still a risk of being bypassed, which can be bypassed by any whitelist prefix /geo/../context-path/. The vulnerability has been fixed in v2.10.4.

The Elated Membership plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.2. This is due to the plugin not properly logging in a user with the data that was previously verified through the 'eltdf_membership_check_facebook_user' and the 'eltdf_membership_login_user_from_social_network' function. This makes it possible for unauthenticated attackers to log in as administrative users, as long as they have an existing account on the site which can easily be created by default through the temp user functionality, and access to the administrative user's email.

Soft Serve is a self-hostable Git server for the command line. Versions 0.11.2 and below have a critical authentication bypass vulnerability that allows an attacker to impersonate any user (including admin) by "offering" the victim's public key during the SSH handshake before authenticating with their own valid key. This occurs because the user identity is stored in the session context during the "offer" phase and is not cleared if that specific authentication attempt fails. This issue has been fixed in version 0.11.3.

Authentication Bypass by Alternate Name vulnerability in DTS Electronics Redline Router firmware allows Authentication Bypass. This issue affects Redline Router: before 7.17.
