The static file controllers in FacturaScripts decide whether a request is authorized by looking at the URL string instead of the canonical filesystem path. A request that starts with an allow-listed folder name but contains a ../ segment in the middle ends up serving a file from a different directory than the one the URL pretended to point at. This makes any file inside the FacturaScripts installation readable without authentication …
WidgetVariante::renderVariantList (Core/Lib/Widget/WidgetVariante.php:298-330) and WidgetSubcuenta::renderSubaccountList (Core/Lib/Widget/WidgetSubcuenta.php:290-321) build the <tr onclick="…"> row for each modal hit by concatenating the user-controlled referencia / codsubcuenta field directly into a single-quoted JavaScript string literal inside an HTML onclick attribute. The defender's intuition is that Tools::noHtml (called in Variante::test() and Subcuenta::test()) replaces ' with the HTML entity ', neutralising the JavaScript string break. The intuition is wrong: HTML attribute parsing decodes character references before the JavaScript …
FacturaScripts\Core\UploadedFile::move($destiny, $destinyName) concatenates $destiny and $destinyName without normalizing the resulting path. Every caller in the codebase passes UploadedFile::getClientOriginalName() — the unsanitized client-supplied filename — as $destinyName, so an authenticated user submitting a filename containing ../ segments can write the uploaded content to any directory writable by the web-server user, escaping the intended MyFiles/ location. Because the shipped htaccess-sample (the documented production Apache configuration) excludes Dinamic/Assets/ and node_modules/ from the index.php …
Live PoC verified 2026-04-30 against a stock FacturaScripts master at 127.0.0.1:8081. A low-privilege user (lowpriv) created a customer with nombre = "=SUM(1+1)*cmd|/c calc!A1". An admin then exported ListCliente to CSV via ?action=export&option=CSV. The downloaded file contains the raw payload as the first cell of the nombre column, with no leading single quote and no escape. Excel and LibreOffice will execute the formula on open, including DDE invocations such as =cmd|'/c …
Live PoC verified 2026-04-30 against a stock FacturaScripts master at 127.0.0.1:8081. A scoped ApiKey with fullaccess=0 and an ApiAccess row granting allowget=1 on the clientes resource only (no other rights, no UI session, no admin) issued one GET /api/3/clientes?filter[(0)UNION%20SELECT%20…]= request and the response body contained the raw bcrypt hash of the admin user's password ($2y$12$sLfA/XCqnjqLmYJwK.2V7eUHrHTHcQfkTYYfs1.lxX3OHrsmmkMGO) and the admin's logkey cookie value. The leaked logkey was injected into a fresh cookie …
Core/Controller/Login.php::twoFactorValidationAction() accepts an unauthenticated POST containing only fsNick and fsTwoFactorCode. If the TOTP value matches, the server issues a full fsNick + fsLogkey session cookie pair. The handler: Does not verify the password — the user is not required to have just completed loginAction. Does not call validateFormToken() — no CSRF token is required (every other action handler in the same file does call it). Does not call userHasManyIncidents() before …
Fectura Scripts is an open-source ERP application, a sensitive information disclosure vulnerability was identified in the Library module's image upload and download pipeline. The application fails to strip EXIF and other embedded metadata from user-uploaded image files before storing them and serving them for download. As a result, any authenticated user who downloads an image from the Library can extract the original uploader's GPS coordinates, device information, timestamps, embedded comments/notes, …
An unauthenticated information disclosure vulnerability in the Installer controller allows any remote attacker to trigger phpinfo() on a fresh FacturaScripts deployment by requesting /?phpinfo=TRUE, exposing full PHP configuration, server environment variables (including any database credentials, API keys, or application secrets set as env vars), filesystem paths, and loaded extensions without being authenticated.
A stored Cross-Site Scripting (XSS) vulnerability exists in the product search modal of sales and purchases documents. An authenticated user with access to the warehouse module can create a product with a malicious reference that executes arbitrary JavaScript in the browser of any other user who opens the product search modal inside an invoice, order, or delivery note.
A Critical vulnerability exists in the Plugins::add() function. The system fails to properly validate the file paths within uploaded ZIP archives. This allows an attacker to perform a Zip Slip attack, leading to Arbitrary File Write and Remote Code Execution (RCE) by overwriting sensitive .php files outside the designated plugins directory.
A Reflected Cross-Site Scripting (XSS) vulnerability exists in the fsNick cookie parameter. The application reflects the cookie's value directly into the HTML without sanitization.
An authenticated unrestricted file upload vulnerability exists in FacturaScripts' product image upload functionality. An attacker with valid credentials can upload a PHP file disguised as a GIF image (using a GIF89a header), bypassing MIME type validation. The file is stored with its original extension, including executable extensions such as .php.
No affected version range available.
FacturaScripts contains a critical SQL Injection vulnerability in the autocomplete functionality that allows authenticated attackers to extract sensitive data from the database including user credentials, configuration settings, and all stored business data. The vulnerability exists in the CodeModel::all() method where user-supplied parameters are directly concatenated into SQL queries without sanitization or parameterized binding.
FacturaScripts contains a critical SQL Injection vulnerability in the REST API that allows authenticated API users to execute arbitrary SQL queries through the sort parameter. The vulnerability exists in the ModelClass::getOrderBy() method where user-supplied sorting parameters are directly concatenated into the SQL ORDER BY clause without validation or sanitization. This affects all API endpoints that support sorting functionality.
A reflected XSS bug has been found in FacturaScripts. The problem is in how error messages get displayed - it's using Twig's | raw filter which skips HTML escaping. When a database error is triggered (like passing a string where an integer is expected), the error message includes all input and gets rendered without sanitization. Attackers can use this to phish credentials from other users since HttpOnly is set on …
A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Observations field. The flaw occurs in the History view, where historical data is rendered without proper HTML entity encoding. This allows an attacker to execute arbitrary JavaScript in the browser of viewing the history by administrators.
