NOTE: the '/' (slash) vector is already covered by CVE-2007-5383.

In multiple Tecson Tankspion and GOKs SmartBox 4 products the affected application doesn't properly restrict access to an endpoint that is responsible for saving settings, to a unauthenticated user with limited access rights. Based on the lack of adequately implemented access-control rules, by accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to change the application settings without authenticating at all, which violates originally laid ACL rules.

Anviz access control devices allow unverified password change which allows remote attackers to change the administrator password without prior authentication.

The RegistrationMagic plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.2.1.0.

The SOAP interface to the eMBox module in Novell eDirectory 8.7.3.9 and earlier, and 8.8.x before 8.8.2, relies on client-side authentication, which allows remote attackers to bypass authentication via requests for /SOAP URIs, and cause a denial of service (daemon shutdown) or read arbitrary files. NOTE: it was later reported that 8.7.3.10 (aka 8.7.3 SP10) is also affected.

A vulnerability was detected in OpenClaw up to 2026.1.24. The impacted element is the function handleBlueBubblesWebhookRequest of the file extensions/bluebubbles/src/monitor.ts of the component bluebubbles Webhook. Performing a manipulation results in improper authentication. It is possible to initiate the attack remotely. The exploit is now public and may be used. Upgrading to version 2026.2.12 is sufficient to resolve this issue. The patch is named a6653be0265f1f02b9de46c06f52ea7c81a836e6. The affected component should be upgraded.

Improper authentication is possible in Apache Traffic Control versions 3.0.0 and 3.0.1 if LDAP is enabled for login in the Traffic Ops API component. Given a username for a user that can be authenticated via LDAP, it is possible to improperly authenticate as that user without that user's correct password.

The Linksys WRT54G router has "admin" as its default FTP password, which allows remote attackers to access sensitive files including nvram.cfg, a file that lists all HTML documents, and an ELF executable file.

The production build of the M3WebServer hard-codes its backend API keys, which can be easily intercepted through verbose error handling pages.

The ExpandCert function in Apache-SSL before apache_1.3.41+ssl_1.59 does not properly handle (1) '/' and (2) '=' characters in a Distinguished Name (DN) in a client certificate, which might allow remote attackers to bypass authentication via a crafted DN that triggers overwriting of environment variables.

In Joomla! before 3.8.2, a bug allowed third parties to bypass a user's 2-factor authentication method.

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).

DMA Softlab Radius Manager 4.4.0 assigns the same session cookie to every admin session. The cookie is valid when the admin is logged in, but is invalid (temporarily) during times when the admin is logged out. In other words, the cookie is functionally equivalent to a static password, and thus provides permanent access if stolen.

Dataprobe iBootBar (with 2007-09-20 and possibly later beta firmware) allows remote attackers to bypass authentication, and conduct power-cycle attacks on connected devices, via a DCCOOKIE cookie.

wolfSSH’s key exchange state machine can be manipulated to leak the client’s password in the clear, trick the client to send a bogus signature, or trick the client into skipping user authentication. This affects client applications with wolfSSH version 1.4.21 and earlier. Users of wolfSSH must update or apply the fix patch and it’s recommended to update credentials used. This fix is also recommended for wolfSSH server applications. While there aren’t any specific attacks on server applications, the same defect is present. Thanks to Aina Toky Rasoamanana of Valeo and Olivier Levillain of Telecom SudParis for the report.

Spring Security, versions 4.2.x up to 4.2.12, and older unsupported versions support plain text passwords using PlaintextPasswordEncoder. If an application using an affected version of Spring Security is leveraging PlaintextPasswordEncoder and a user has a null encoded password, a malicious user (or attacker) can authenticate using a password of "null".

An attacker can export system configuration which is not encrypted to get the administrator’s account and password in plain text via cgibin/ExportSettings.cgi?Export=1 without any authentication.

YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.

SQLLoginModule in Apache Geronimo 2.0 through 2.1 does not throw an exception for a nonexistent username, which allows remote attackers to bypass authentication via a login attempt with any username not contained in the database.
