Vulnerabilidades

*** Pendiente de traducción *** A vulnerability was detected in wasm3 up to 0.5.0. Impacted is the function op_SetSlot_i32/op_CallIndirect of the file m3_exec.h. Performing a manipulation results in memory corruption. The attack needs to be approached locally. The exploit is now public and may be used. Unfortunately, the project has no active maintainer at the moment.

*** Pendiente de traducción *** A weakness has been identified in WebAssembly wabt up to 1.0.39. This vulnerability affects the function wabt::AST::InsertNode of the file /src/repro/wabt/bin/wasm-decompile of the component wasm-decompile. This manipulation causes memory corruption. It is possible to launch the attack on the local host. The exploit has been made available to the public and could be used for attacks. Unfortunately, the project has no active maintainer at the moment. In a reply to the issue report somebody recommended to the researcher to provide a PR himself.

*** Pendiente de traducción *** Signal K Server is a server application that runs on a central hub in a boat. Versions prior to 2.19.0 of the access request system have two related features that when combined by themselves and with an information disclosure vulnerability enable convincing social engineering attacks against administrators. When a device creates an access request, it specifies three fields: `clientId`, `description`, and `permissions`. The SignalK admin UI displays the `description` field prominently to the administrator when showing pending requests, but the actual `permissions` field (which determines the access level granted) is less visible or displayed separately. This allows an attacker to request `admin` permissions while providing a description that suggests readonly access. The access request handler trusts the `X-Forwarded-For` HTTP header without validation to determine the client's IP address. This header is intended to preserve the original client IP when requests pass through reverse proxies, but when trusted unconditionally, it allows attackers to spoof their IP address. The spoofed IP is displayed to administrators in the access request approval interface, potentially making malicious requests appear to originate from trusted internal network addresses. Since device/source names can be enumerated via the information disclosure vulnerability, an attacker can impersonate a legitimate device or source, craft a convincing description, spoof a trusted internal IP address, and request elevated permissions, creating a highly convincing social engineering scenario that increases the likelihood of administrator approval. Users should upgrade to version 2.19.0 to fix this issue.

*** Pendiente de traducción *** Signal K Server is a server application that runs on a central hub in a boat. Versions prior to 2.19.0 expose two features that can be chained together to steal JWT authentication tokens without any prior authentication. The attack combines WebSocket-based request enumeration with unauthenticated polling of access request status. The first is Unauthenticated WebSocket Request Enumeration: When a WebSocket client connects to the SignalK stream endpoint with the `serverevents=all` query parameter, the server sends all cached server events including `ACCESS_REQUEST` events that contain details about pending access requests. The `startServerEvents` function iterates over `app.lastServerEvents` and writes each cached event to any connected client without verifying authorization level. Since WebSocket connections are allowed for readonly users (which includes unauthenticated users when `allow_readonly` is true), attackers receive these events containing request IDs, client identifiers, descriptions, requested permissions, and IP addresses. The second is Unauthenticated Token Polling: The access request status endpoint at `/signalk/v1/access/requests/:id` returns the full state of an access request without requiring authentication. When an administrator approves a request, the response includes the issued JWT token in plaintext. The `queryRequest` function returns the complete request object including the token field, and the REST endpoint uses readonly authentication, allowing unauthenticated access. An attacker has two paths to exploit these vulnerabilities. Either the attacker creates their own access request (using the IP spoofing vulnerability to craft a convincing spoofed request), then polls their own request ID until an administrator approves it, receiving the JWT token; or the attacker passively monitors the WebSocket stream to discover request IDs from legitimate devices, then polls those IDs and steals the JWT tokens when administrators approve them, hijacking legitimate device credentials. Both paths require zero authentication and enable complete authentication bypass. Version 2.19.0 fixes the underlying issues.

*** Pendiente de traducción *** Signal K Server is a server application that runs on a central hub in a boat. Versions prior to 2.19.0 of the appstore interface allow administrators to install npm packages through a REST API endpoint. While the endpoint validates that the package name exists in the npm registry as a known plugin or webapp, the version parameter accepts arbitrary npm version specifiers including URLs. npm supports installing packages from git repositories, GitHub shorthand syntax, and HTTP/HTTPS URLs pointing to tarballs. When npm installs a package, it can automatically execute any `postinstall` script defined in `package.json`, enabling arbitrary code execution. The vulnerability exists because npm's version specifier syntax is extremely flexible, and the SignalK code passes the version parameter directly to npm without sanitization. An attacker with admin access can install a package from an attacker-controlled source containing a malicious `postinstall` script. Version 2.19.0 contains a patch for the issue.

*** Pendiente de traducción *** Signal K Server is a server application that runs on a central hub in a boat. An unauthenticated information disclosure vulnerability in versions prior to 2.19.0 allows any user to retrieve sensitive system information, including the full SignalK data schema, connected serial devices, and installed analyzer tools. This exposure facilitates reconnaissance for further attacks. Version 2.19.0 patches the issue.

*** Pendiente de traducción *** A vulnerability was identified in code-projects Online Guitar Store 1.0. Affected by this issue is some unknown functionality of the file /login.php. The manipulation of the argument L_email leads to sql injection. It is possible to initiate the attack remotely. The exploit is publicly available and might be used.

cpp-httplib es una biblioteca HTTP/HTTPS multiplataforma de un solo archivo de cabecera C++11. Antes de la versión 0.30.0, la función 'write_headers' no verifica la presencia de caracteres CR y LF en las cabeceras proporcionadas por el usuario, lo que permite que un valor de cabecera no confiable escape las líneas de cabecera. Esta vulnerabilidad permite a los atacantes añadir cabeceras adicionales, modificar el cuerpo de la solicitud de forma inesperada y desencadenar un ataque SSRF. Cuando se combina con un servidor que soporta el pipelining de http1.1 (springboot, python twisted, etc.), esto puede utilizarse para la falsificación de solicitudes del lado del servidor (SSRF). La versión 0.30.0 corrige este problema.

eopkg es un gestor de paquetes de Solus implementado en python3. En versiones anteriores a la 4.4.0, un paquete malicioso podría incluir archivos que no son rastreados por 'eopkg'. Esto requiere la instalación de un paquete de una fuente maliciosa o comprometida. Los archivos en dichos paquetes no serían mostrados por 'lseopkg' y herramientas relacionadas. El problema ha sido solucionado en la v4.4.0. Los usuarios que solo instalan paquetes de los repositorios de Solus no se ven afectados.

eopkg es un gestor de paquetes de Solus implementado en python3. En versiones anteriores a la 4.4.0, un paquete malicioso podría escapar del directorio establecido por `--destdir`. Esto requiere la instalación de un paquete de una fuente maliciosa o comprometida. Los archivos en dichos paquetes no se instalarían en la ruta especificada por `--destdir`, sino en una ubicación diferente en el host. El problema ha sido solucionado en la v4.4.0. Los usuarios que solo instalan paquetes de los repositorios de Solus no se ven afectados.
