In addition, the attacker may tamper with firmware for them using the disclosed information.

Multiple W&T products of the ComServer Series are prone to an authentication bypass. An unathenticated remote attacker, can log in without knowledge of the password by crafting a modified HTTP GET Request.

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 22.0.1026 and Application prior to version 20.0.2702 (VA deployments only) expose a set of unauthenticated REST API endpoints that return configuration files and clear‑text passwords. The same endpoints also disclose the Laravel APP_KEY used for cryptographic signing. Because the APP_KEY is required to generate valid signed requests, an attacker who obtains it can craft malicious payloads that are accepted by the application and achieve remote code execution on the appliance. This vulnerability has been identified by the vendor as: V-2024-018 — RCE & Leaks via API.

An unauthenticated arbitrary file upload vulnerability exists in Idera Up.Time Monitoring Station versions up to and including 7.2. The `wizards/post2file.php` script accepts arbitrary POST parameters, allowing attackers to upload crafted PHP files to the webroot. Successful exploitation results in remote code execution as the web server user. NOTE: The bypass for this vulnerability is tracked as CVE-2015-9263.

A remote code execution vulnerability exists in CryptoLog (PHP version, discontinued since 2009) due to a chained exploitation of SQL injection and command injection vulnerabilities. An unauthenticated attacker can gain shell access as the web server user by first exploiting a SQL injection flaw in login.php to bypass authentication, followed by command injection in logshares_ajax.php to execute arbitrary operating system commands. The login bypass is achieved by submitting crafted SQL via the user POST parameter. Once authenticated, the attacker can abuse the lsid POST parameter in the logshares_ajax.php endpoint to inject and execute a command using $(...) syntax, resulting in code execution under the web context. This exploitation path does not exist in the ASP.NET version of CryptoLog released since 2009.

The Quantenna Wi-Fi chips ship with an unauthenticated telnet interface by default. This is an instance of CWE-306, "Missing Authentication for Critical Function," and is estimated as a CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). This issue affects Quantenna Wi-Fi chipset through version 8.0.0.28 of the latest SDK, and appears to be unpatched at the time of this CVE record's first publishing, though the vendor has released a best practices guide for implementors of this chipset.

An unauthenticated remote command execution vulnerability exists in Samsung WLAN AP WEA453e firmware prior to version 5.2.4.T1 via improper input validation in the “Tech Support” diagnostic functionality. The command1 and command2 POST or GET parameters accept arbitrary shell commands that are executed with root privileges on the underlying operating system. An attacker can exploit this by crafting a request that injects shell commands to create output files in writable directories and then access their contents via the download endpoint. This flaw allows complete compromise of the device without authentication. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-04 UTC.

A remote code execution vulnerability exists in multiple Netcore and Netis routers models with firmware released prior to August 2014 due to the presence of an undocumented backdoor listener on UDP port 53413. Exact version boundaries remain undocumented. An unauthenticated remote attacker can send specially crafted UDP packets to execute arbitrary commands on the affected device. This backdoor uses a hardcoded authentication mechanism and accepts shell commands post-authentication. Some device models include a non-standard implementation of the `echo` command, which may affect exploitability.

Entrust Instant Financial Issuance (IFI) On Premise software (formerly referred to as CardWizard) versions 5.x, prior to 6.10.5, and prior to 6.11.1 contain an insecure .NET Remoting exposure in the Legacy Remoting Service that is enabled by default. The service registers a TCP remoting channel with SOAP and binary formatters configured at TypeFilterLevel=Full and exposes default ObjectURI endpoints such as logfile.rem, photo.rem, cwPhoto.rem, and reports.rem on a network-reachable remoting port. A remote, unauthenticated attacker who can reach the remoting port can invoke exposed remoting objects to read arbitrary files from the server and coerce outbound authentication, and may achieve arbitrary file write and remote code execution via known .NET Remoting exploitation techniques. This can lead to disclosure of sensitive installation and service-account data and compromise of the affected host.

An authentication bypass vulnerability exists in GFI Kerio Control 9.4.5 due to insecure default proxy configuration and weak access control in the GFIAgent service. The non-transparent proxy on TCP port 3128 can be used to forward unauthenticated requests to internal services such as GFIAgent, bypassing firewall restrictions and exposing internal management endpoints. This enables unauthenticated attackers to access the GFIAgent service on ports 7995 and 7996, retrieve the appliance UUID, and issue administrative requests via the proxy. Exploitation results in full administrative access to the Kerio Control appliance.

An unauthenticated arbitrary file upload vulnerability exists in Tiki Wiki CMS Groupware version 15.1 and earlier via the ELFinder component's default connector (connector.minimal.php), which allows remote attackers to upload and execute malicious PHP scripts in the context of the web server. The vulnerable component does not enforce file type validation, allowing attackers to craft a POST request to upload executable PHP payloads through the ELFinder interface exposed at /vendor_extra/elfinder/.

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 22.0.1026 and Application prior to version 20.0.2702 (only VA deployments) expose an unauthenticated firmware-upload flow: a public page returns a signed token usable at va-api/v1/update, and every Docker image contains the appliance’s private GPG key and hard-coded passphrase. An attacker who extracts the key and obtains a token can decrypt, modify, re-sign, upload, and trigger malicious firmware, gaining remote code execution. This vulnerability has been identified by the vendor as: V-2024-020 — Remote Code Execution.

An unauthenticated command injection vulnerability exists in WePresent WiPG-1000 firmware versions prior to 2.2.3.0, due to improper input handling in the undocumented /cgi-bin/rdfs.cgi endpoint. The Client parameter is not sanitized before being passed to a system call, allowing an unauthenticated remote attacker to execute arbitrary commands as the web server user.

Nginx UI is a web user interface for the Nginx web server. From version 2.0.0 to before version 2.3.8, an unauthenticated network attacker can claim the initial administrator account on a fresh nginx-ui instance during the first-run setup window. The public /api/install endpoint is reachable without authentication, and the request-encryption flow only protects payload confidentiality in transit; it does not authenticate who is allowed to perform installation. A remote attacker who reaches the service before the legitimate operator can set the admin email, username, and password, causing permanent initial-instance takeover. This issue has been patched in version 2.3.8.

An unauthenticated command injection vulnerability exists in Serviio Media Server versions 1.4 through 1.8 on Windows, in the /rest/action API endpoint exposed by the console component (default port 23423). The checkStreamUrl method accepts a VIDEO parameter that is passed unsanitized to a call to cmd.exe, enabling arbitrary command execution under the privileges of the web server. No authentication is required to exploit this issue, as the REST API is exposed by default and lacks access controls.

BSS Continuity CMS 4.2.22640.0 has an Authentication Bypass vulnerability

An issue was discovered in genua genugate before 9.0 Z p19, 9.1.x through 9.6.x before 9.6 p7, and 10.x before 10.1 p4. The Web Interfaces (Admin, Userweb, Sidechannel) can use different methods to perform the authentication of a user. A specific authentication method during login does not check the provided data (when a certain manipulation occurs) and returns OK for any authentication request. This allows an attacker to login to the admin panel as a user of his choice, e.g., the root user (with highest privileges) or even a non-existing user.

Langflow versions prior to 1.3.0 are susceptible to code injection in the /api/v1/validate/code endpoint. A remote and unauthenticated attacker can send crafted HTTP requests to execute arbitrary code.

A request-validation issue was discovered in Open5GS 2.1.3 through 2.2.x before 2.2.1. The WebUI component allows an unauthenticated user to use a crafted HTTP API request to create, read, update, or delete entries in the subscriber database. For example, new administrative users can be added. The issue occurs because Express is not set up to require authentication.

CrowdStrike has released security updates to address a critical unauthenticated path traversal vulnerability (CVE-2026-40050) in LogScale. This vulnerability only requires mitigation by customers that host specific versions of LogScale and does not affect Next-Gen SIEM customers. The vulnerability exists in a specific cluster API endpoint that, if exposed, allows a remote attacker to read arbitrary files from the server filesystem without authentication. Next-Gen SIEM customers are not affected and do not need to take any action. CrowdStrike mitigated the vulnerability for LogScale SaaS customers by deploying network-layer blocks to all clusters on April 7, 2026. We have proactively reviewed all log data and there is no evidence of exploitation. LogScale Self-hosted customers should upgrade to a patched version immediately to remediate the vulnerability. CrowdStrike identified this vulnerability during continuous and ongoing product testing.

NetAlertX is a network, presence scanner and alert framework. Prior to version 25.4.14, it is possible to bypass the authentication mechanism of NetAlertX to update settings without authentication. An attacker can trigger sensitive functions within util.php by sending crafted requests to /index.php. This issue has been patched in version 25.4.14.

Voltronic Power ViewPower through 1.04-21353 and PowerShield Netguard before 1.04-23292 allows a remote attacker to configure the system via an unspecified web interface. An unauthenticated remote attacker can make changes to the system including: changing the web interface admin password, view/change system configuration, enumerate connected UPS devices and shut down connected UPS devices. This extends to being able to configure operating system commands that should run if the system detects a connected UPS shutting down.

This vulnerability occurs when a WebSocket endpoint does not enforce proper authentication mechanisms, allowing unauthorized users to establish connections. As a result, attackers can exploit this weakness to gain unauthorized access to sensitive data or perform unauthorized actions. Given that no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.

A missing authentication for critical function vulnerability [CWE-306] in FortiPresence infrastructure server before version 1.2.1 allows a remote, unauthenticated attacker to access the Redis and MongoDB instances via crafted authentication requests.

Delta Electronics InfraSuite Device Master versions 00.00.01a and prior lack proper authentication for functions that create and modify user groups. An attacker could provide malicious serialized objects that could run these functions without authentication to create a new user and add them to the administrator group.

OneUptime is an open-source monitoring and observability platform. Prior to version 10.0.42, the Worker service's ManualAPI exposes workflow execution endpoints (GET /workflow/manual/run/:workflowId and POST /workflow/manual/run/:workflowId) without any authentication middleware. An attacker who can obtain or guess a workflow ID can trigger arbitrary workflow execution with attacker-controlled input data, enabling JavaScript code execution, notification abuse, and data manipulation. This issue has been patched in version 10.0.42.

Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 22.0.933 Application 20.0.2368 allows Unauthenticated Driver Package Editing V-2024-008.

Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 22.0.913 Application 20.0.2253 allows Addition of Partial Admin Users Without Authentication V-2024-002.

Nginx UI is a web user interface for the Nginx web server. In versions 2.3.5 and prior, the nginx-ui MCP (Model Context Protocol) integration exposes two HTTP endpoints: /mcp and /mcp_message. While /mcp requires both IP whitelisting and authentication (AuthRequired() middleware), the /mcp_message endpoint only applies IP whitelisting - and the default IP whitelist is empty, which the middleware treats as "allow all". This means any network attacker can invoke all MCP tools without authentication, including restarting nginx, creating/modifying/deleting nginx configuration files, and triggering automatic config reloads - achieving complete nginx service takeover. At time of publication, there are no publicly available patches.

An attacker could provide malicious serialized objects which, when deserialized, could activate an opcode for a backup scheduling function without authentication. This function allows the user to designate all function arguments and the file to be executed. This could allow the attacker to start any new process and achieve remote code execution.

There is no account authentication and permission check logic in the firmware and existing apps of SiHAS's SGW-300, ACM-300, GCM-300, so unauthorized users can remotely control the device.

Improper configuration of the SSH service in Infinera MTC-9 allows an unauthenticated attacker to execute arbitrary commands and access data on file system . This issue affects MTC-9: from R22.1.1.0275 before R23.0.

The LatePoint plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.0.12. This is due to insufficient verification on the user being supplied during the booking customer step. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id. Note that logging in as a WordPress user is only possible if the "Use WordPress users as customers" setting is enabled, which is disabled by default. The vulnerability is partially patched in version 5.0.12 and fully patched in version 5.0.13.
