An issue was discovered in WildFly 10.1.2.Final. In the case of a default installation without a security realm reference, an attacker can successfully access the server without authentication. NOTE: the Security Realms documentation in the product's Admin Guide indicates that "without a security realm reference" implies "effectively unsecured." The vendor explicitly supports these unsecured configurations because they have valid use cases during development

An issue was discovered in WildFly 10.1.2.Final. It is possible for an attacker to access the administration panel on TCP port 9990 without any authentication using "anonymous" access that is automatically created. Once logged in, a misconfiguration present by default (auto-deployment) permits an anonymous user to deploy a malicious .war file, leading to remote code execution. NOTE: the vendor indicates that anonymous access is not available in the default installation; however, it remains optional because there are several use cases for it, including development environments and network architectures that have a proxy server for access control to the WildFly server

The Motorola ACE1000 RTU through 2022-05-02 has default credentials. It exposes an SSH interface on port 22/TCP. This interface is used for remote maintenance and for SFTP file-transfer operations that are part of engineering software functionality. Access to this interface is controlled by 5 preconfigured accounts (root, abuilder, acelogin, cappl, ace), all of which come with default credentials. Although the ACE1000 documentation mentions the root, abuilder and acelogin accounts and instructs users to change the default credentials, the cappl and ace accounts remain undocumented and thus are unlikely to have their credentials changed.

The RingCentral Communications plugin for WordPress is vulnerable to Authentication Bypass due to improper validation within the ringcentral_admin_login_2fa_verify() function in versions 1.5 to 1.6.8. This makes it possible for unauthenticated attackers to log in as any user simply by supplying identical bogus codes.

authentik is an open-source identity provider. When initialising a oauth2 flow with a `code_challenge` and `code_method` (thus requesting PKCE), the single sign-on provider (authentik) must check if there is a matching and existing `code_verifier` during the token step. Prior to versions 2023.10.4 and 2023.8.5, authentik checks if the contents of `code_verifier` is matching only when it is provided. When it is left out completely, authentik simply accepts the token request with out it; even when the flow was started with a `code_challenge`. authentik 2023.8.5 and 2023.10.4 fix this issue.

Unauthorized access to Gateway user capabilities

PKCE was implemented in the OAuth implementation in workers-oauth-provider that is part of MCP framework https://github.com/cloudflare/workers-mcp . However, it was found that an attacker could cause the check to be skipped. Fixed in: https://github.com/cloudflare/workers-oauth-provider/pull/27 https://github.com/cloudflare/workers-oauth-provider/pull/27 Impact: PKCE is a defense-in-depth mechanism against certain kinds of attacks and was an optional extension in OAuth 2.0 which became required in the OAuth 2.1 draft. (Note that the MCP specification requires OAuth 2.1.). This bug completely bypasses PKCE protection.
