A vulnerability in session management for the web-based interface of Cisco Small Business Smart and Managed Switches could allow an unauthenticated, remote attacker to defeat authentication protections and gain unauthorized access to the management interface. The attacker could obtain the privileges of the highjacked session account, which could include administrator privileges on the device. The vulnerability is due to the use of weak entropy generation for session identifier values. An attacker could exploit this vulnerability to determine a current session identifier through brute force and reuse that session identifier to take over an ongoing session. In this way, an attacker could take actions within the management interface with privileges up to the level of the administrative user.

An issue was discovered on Dasan GPON home routers. It is possible to bypass authentication simply by appending "?images" to any URL of the device that requires authentication, as demonstrated by the /menu.html?images/ or /GponForm/diag_FORM?images/ URI. One can then manage the device.

The ASUS DSL-N17U modem with firmware 1.1.0.2 allows attackers to access the admin interface by changing the admin password without authentication via a POST request to Advanced_System_Content.asp with the uiViewTools_username=admin&uiViewTools_Password= and uiViewTools_PasswordConfirm= substrings.

Dell Storage Center - Dell Storage Manager, version(s) 20.1.21, contain(s) an Improper Authentication vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass. Authentication Bypass in DSM Data Collector. An unauthenticated remote attacker can access APIs exposed by ApiProxy.war in DataCollectorEar.ear by using a special SessionKey and UserId. These userid are special users created in compellentservicesapi for special purposes.

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.

A vulnerability classified as critical has been found in Private Cloud Management Platform. Affected is an unknown function of the file /management/api/rcx_management/global_config_query of the component POST Request Handler. The manipulation leads to improper authentication. It is possible to launch the attack remotely. VDB-205614 is the identifier assigned to this vulnerability.

Barco wePresent WiPG-1600W devices allow Authentication Bypass. Affected Version(s): 2.5.1.8. The Barco wePresent WiPG-1600W web interface does not use session cookies for tracking authenticated sessions. Instead, the web interface uses a "SEID" token that is appended to the end of URLs in GET requests. Thus the "SEID" would be exposed in web proxy logs and browser history. An attacker that is able to capture the "SEID" and originate requests from the same IP address (via a NAT device or web proxy) would be able to access the user interface of the device without having to know the credentials.

In Alerta before version 8.1.0, users may be able to bypass LDAP authentication if they provide an empty password when Alerta server is configure to use LDAP as the authorization provider. Only deployments where LDAP servers are configured to allow unauthenticated authentication mechanism for anonymous authorization are affected. A fix has been implemented in version 8.1.0 that returns HTTP 401 Unauthorized response for any authentication attempts where the password field is empty. As a workaround LDAP administrators can disallow unauthenticated bind requests by clients.

Unauthorized access to Gateway user capabilities

The Linux-PAM package before 1.5.2-6.1 for openSUSE Tumbleweed allows authentication bypass for SSH logins. The pam_access.so module doesn't correctly restrict login if a user tries to connect from an IP address that is not resolvable via DNS. In such conditions, a user with denied access to a machine can still get access. NOTE: the relevance of this issue is largely limited to openSUSE Tumbleweed and openSUSE Factory; it does not affect Linux-PAM upstream.

In cPanel before 88.0.3, insecure chkservd test credentials are used on a templated VM (SEC-554).

A vulnerability, which was classified as critical, was found in holdennb CollabCal. Affected is the function handleGet of the file calenderServer.cpp. The manipulation leads to improper authentication. It is possible to launch the attack remotely.

The communication protocol implemented in Ghost Robotics Vision 60 v0.27.2 could allow an attacker to send commands to the robot from an external attack station, impersonating the control station (tablet) and gaining unauthorised full control of the robot. The absence of encryption and authentication mechanisms in the communication protocol allows an attacker to capture legitimate traffic between the robot and the controller, replicate it, and send any valid command to the robot from any attacking computer or device. The communication protocol used in this interface is based on MAVLink, a widely documented protocol, which increases the likelihood of attack. There are two methods for connecting to the robot remotely: Wi-Fi and 4G/LTE.

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".

The remotely accessible Java servlet com.manageengine.ads.fw.servlet.UpdateProductDetails is prone to an authentication bypass. System integration properties can be modified and lead to full ManageEngine suite compromise.

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.

An issue was discovered in Dynamicweb before 9.12.8. An attacker can add a new administrator user without authentication. This flaw exists due to a logic issue when determining if the setup phases of the product can be run again. Once an attacker is authenticated as the new admin user they have added, it is possible to upload an executable file and achieve command execution. This is fixed in 9.5.9, 9.6.16, 9.7.8, 9.8.11, 9.9.8, 9.10.18, 9.12.8, and 9.13.0 (and later).

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.

Cron log backup files contain administrator session IDs. It is trivial for any attacker who can reach the Pandora FMS Console to scrape the cron logs directory for cron log backups. The contents of these log files can then be abused to authenticate to the application as an administrator. This issue affects Pandora FMS <= 772.

TeslaMate before 1.25.1 (when using the default Docker configuration) allows attackers to open doors of Tesla vehicles, start Keyless Driving, and interfere with vehicle operation en route. This occurs because an attacker can leverage Grafana login access to obtain a token for Tesla API calls.

Sysaid – Sysaid System Takeover - An attacker can bypass the authentication process by accessing to: /wmiwizard.jsp, Then to: /ConcurrentLogin.jsp, then click on the login button, and it will redirect you to /home.jsp without any authentication.

Softing Secure Integration Server, edgeConnector, and edgeAggregator software ships with the default administrator credentials as `admin` and password as `admin`. This allows Softing to log in to the server directly to perform administrative functions. Upon installation or upon first login, the application does not ask the user to change the `admin` password. There is no warning or prompt to ask the user to change the default password, and to change the password, many steps are required.

Multiple Lenze products of the cabinet series skip the password verification upon second login. After a user has been logged on to the device once, a remote attacker can get full access without knowledge of the password.

An issue was discovered on Crestron HD-MD4X2-4K-E 1.0.0.2159 devices.
