Invoice Ninja before 5.10.43 allows remote code execution from a pre-authenticated route when an attacker knows the APPKEY. This is exacerbated by .env files, available from the product's repository, that have default APPKEY values. The route/{hash} route defined in the invoiceninja/routes/client.php file can be accessed without authentication. The parameter {hash} is passed to the function decrypt that expects a Laravel ciphered value containing a serialized object. (Furthermore, Laravel contains several gadget chains usable to trigger remote command execution from arbitrary deserialization.) Therefore, an attacker in possession of the APPKEY is able to fully control a string passed to an unserialize function.

InvoiceNinja v5-stable renders an invoice or quote's "terms" field in the client portal using Laravel Blade's raw output directive {!! ->terms !!} (resources/views/portal/ninja2020/invoices/includes/terms.blade.php) with no HTML sanitization.

Incorrect handling of uploaded files in the admin "Restore" function in Invoice Ninja <= 5.11.72 allows attackers with admin credentials to execute arbitrary code on the server via uploaded .php files.

Invoice Ninja is vulnerable to authenticated Server-Side Request Forgery (SSRF) allowing for arbitrary file read and network resource requests as the application user. This issue affects Invoice Ninja: from 5.8.56 through 5.11.23.

Invoice Ninja v5.12.46 and v5.12.48 is vulnerable to Server-Side Request Forgery (SSRF) in CheckDatabaseRequest.php.

Invoice Ninja is a source-available invoice, quote, project and time-tracking app built with Laravel. Product notes fields in Invoice Ninja v5.13.0 allow raw HTML via Markdown rendering, enabling stored XSS. The Markdown parser output was not sanitized with purify::clean() before being included in invoice templates. This is fixed in v5.13.4 by the vendor by adding purify::clean() to sanitize Markdown output.

Invoice Ninja through 5.13.26 contains an open redirect vulnerability in the client portal login that allows unauthenticated attackers to redirect authenticated victims to attacker-controlled external URLs by injecting a malicious value into the intended query parameter. Attackers can craft a client login link with an external URL in the intended parameter, which is stored in the session without host validation and emitted verbatim via a bare redirect in the ContactLoginController authenticated() handler after the victim completes a legitimate login, enabling phishing attacks.

Invoice Ninja's configuration on macOS, specifically the presence of entitlement "com.apple.security.get-task-allow", allows local attackers with unprivileged access (e.g. via a malicious application) to attach a debugger, read or modify the process memory, inject code in the application's context despite being signed with Hardened Runtime and bypass Transparency, Consent, and Control (TCC). Acquired resource access is limited to previously granted permissions by the user. Access to other resources beyond granted permissions requires user interaction with a system prompt asking for permission.

According to Apple documentation, when a non-root user runs an app with the debugging tool entitlement, the system presents an authorization dialog asking for a system administrator's credentials. Since there is no prompt when the target process has "get-task-allow" entitlement, the presence of this entitlement was decided to be treated as a vulnerability because it removes one step needed to perform an attack.

This issue was fixed in version 5.0.175

A weakness has been identified in invoiceninja Invoice Ninja up to 5.13.26. This affects an unknown part of the file /vedor/profile/ of the component Vendor Portal Profile Update. Executing a manipulation of the argument vendorcontact can lead to authorization bypass. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. Upgrading to version 5.13.27 is able to mitigate this issue. This patch is called f86fd9697ce7bd0d28adbe2e6c5890780482ea90. The affected component should be upgraded.

A security vulnerability has been detected in invoiceninja Invoice Ninja up to 5.13.26. This vulnerability affects the function Purify::isHostSafe of the file app/Services/Pdf/Purify.php of the component invoices Endpoint. The manipulation of the argument notes leads to server-side request forgery. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
