CVE-2024-47051·PHP vulnerability

This advisory addresses two critical security vulnerabilities present in Mautic versions before 5.2.3. These vulnerabilities could be exploited by authenticated users. * Remote Code Execution (RCE) via Asset Upload: A Remote Code Execution vulnerability has been identified in the asset upload functionality. Insufficient enforcement of allowed file extensions allows an attacker to bypass restrictions and upload executable files, such as PHP scripts. * Path Traversal File Deletion: A Path Traversal vulnerability exists in the upload validation process. Due to improper handling of path components, an authenticated user can manipulate the file deletion process to delete arbitrary files on the host system.

How to fix this CVE

Upgrade PHP to version 5.2.3 or later to patch two critical vulnerabilities in the asset upload and file deletion mechanisms. These flaws allow authenticated attackers to upload malicious code and delete arbitrary files on the server. Apply the update immediately using your distribution's package manager and restart the PHP service to ensure the fix takes effect.

sudo dnf update php

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST /app/bundles/AssetBundle/assets/ followed by file upload with .php, .phtml, or other executable extension in Content-Disposition header; or DELETE requests with path traversal sequences (../ or %2e%2e%2f) in the file path parameter

WAF mitigation (if patching is not yet possible)

Add this rule to your WAF to block exploitation attempts while you schedule the patch. 

Implement file upload restrictions at the WAF level: block any POST requests to asset upload endpoints containing executable extensions (.php, .phtml, .php3, .php4, .php5, .phar, .inc); validate that uploaded files match declared MIME types; block path traversal patterns in all request parameters matching ^.*(\.\.|%2e%2e|%252e%252e)

How to check if you are affected

  1. Check installed PHP version: php -v
  2. Verify Mautic installation path and version: grep -r '"version"' /path/to/mautic/app/config.php or check /app/release_metadata.json
  3. Search web server logs for suspicious file uploads to asset directories: grep -i 'POST.*asset' /var/log/apache2/access.log or /var/log/nginx/access.log
  4. Confirm patch applied by running php -v again and verifying version is 5.2.3 or higher; check file integrity: ls -la /path/to/mautic/app/ | grep -E '(upload|asset)' for unexpected executable files

FAQ

What is CVE-2024-47051?

CVE-2024-47051 comprises two critical security flaws in Mautic versions before 5.2.3 that allow authenticated users to upload executable PHP files by bypassing file extension validation, and to delete arbitrary files through path traversal in the upload validation logic.

Is CVE-2024-47051 being actively exploited?

No, CVE-2024-47051 is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog, and no public exploits are available. However, the critical CVSS score of 9.1 makes it a high-priority patch due to its severity.

What versions of PHP are affected by CVE-2024-47051?

All Mautic versions before 5.2.3 are affected. The vulnerability impacts authenticated users, so systems where access controls are not properly configured face greater risk.

How do I check if my server is vulnerable to CVE-2024-47051?

Run php -v to check your PHP version, then verify your Mautic version by checking the version string in config files or the web interface. If your Mautic version is below 5.2.3, the system is vulnerable.

Does Defensia detect CVE-2024-47051?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If PHP with Mautic is installed on a monitored server, CVE-2024-47051 will appear in your dashboard with remediation steps.

CVE-2026-28289CVSS 10FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. A patch bypass vulnerability for CVE-2026-27636 in FreeScout 1.8.206 and earlier allows any authenticated user with file upload permissions to achieve Remote Code Execution (RCE) on the server by uploading a malicious .htaccess file using a zero-width space character prefix to bypass the security check. The vulnerability exists in the sanitizeUploadedFileName() function in app/Http/Helper.php. The function contains a Time-of-Check to Time-of-Use (TOCTOU) flaw where the dot-prefix check occurs before sanitization removes invisible characters. This vulnerability is fixed in 1.8.207.
CVE-2025-46348CVSS 10YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.
CVE-2025-47916CVSS 10Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.
CVE-2025-25174CVSS 10Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in beeteam368 BeeTeam368 Extensions beeteam368-extensions allows PHP Local File Inclusion.This issue affects BeeTeam368 Extensions: from n/a through <= 1.9.4.
CVE-2025-62521CVSS 10ChurchCRM is an open-source church management system. Prior to version 5.21.0, a pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The vulnerability exists in `setup/routes/setup.php` where user input from the setup form is directly concatenated into a PHP configuration template without any validation or sanitization. Any parameter in the setup form can be used to inject PHP code that gets written to `Include/Config.php`, which is then executed on every page load. This is more severe than typical authenticated RCE vulnerabilities because it requires no credentials and affects the installation process that administrators must complete. Version 5.21.0 patches the issue.
