CVE-2024-7553·PHP vulnerability

Incorrect validation of files loaded from a local untrusted directory may allow local privilege escalation if the underlying operating systems is Windows. This may result in the application executing arbitrary behaviour determined by the contents of untrusted files. This issue affects MongoDB Server v5.0 versions prior to 5.0.27, MongoDB Server v6.0 versions prior to 6.0.16, MongoDB Server v7.0 versions prior to 7.0.12, MongoDB Server v7.3 versions prior 7.3.3, MongoDB C Driver versions prior to 1.26.2 and MongoDB PHP Driver versions prior to 1.18.1. Required Configuration: Only environments with Windows as the underlying operating system is affected by this issue

How to fix this CVE

Update the MongoDB PHP Driver to version 1.18.1 or later to resolve this local privilege escalation vulnerability on Windows systems. The vulnerability stems from improper validation of files loaded from untrusted local directories, which could allow an attacker with local access to execute arbitrary code with elevated privileges. Affected systems should prioritize this update, particularly Windows-based deployments where the attack surface is exposed.

How to check if you are affected

  1. Step 1: Run `php -m | grep mongodb` or `php -i | grep -A 5 'mongo'` to verify the MongoDB PHP Driver is installed and check the version string
  2. Step 2: Execute `php -r "echo phpversion('mongodb');"` to retrieve the exact installed driver version and compare against 1.18.1
  3. Step 3: Check Windows event logs for unexpected process creation or privilege escalation events originating from PHP processes, particularly in Security logs (Event ID 4688)
  4. Step 4: After patching, re-run `php -r "echo phpversion('mongodb');"` to confirm the version is now 1.18.1 or higher

FAQ

What is CVE-2024-7553?

CVE-2024-7553 is a local privilege escalation vulnerability in the MongoDB PHP Driver where insufficient validation of files loaded from untrusted local directories on Windows systems allows a local attacker to execute arbitrary code with elevated permissions.

Is CVE-2024-7553 being actively exploited?

No, CVE-2024-7553 is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog and no public exploits are currently available, though the high CVSS score (7.3) warrants prompt patching.

What versions of PHP are affected by CVE-2024-7553?

The MongoDB PHP Driver versions prior to 1.18.1 are vulnerable. This affects PHP installations using the pecl-mongodb extension in versions 1.18.0 and earlier.

How do I check if my server is vulnerable to CVE-2024-7553?

Run `php -r "echo phpversion('mongodb');"` on your server. If the output is a version number lower than 1.18.1, your system is vulnerable. Note: This vulnerability only affects Windows-based servers.

Does Defensia detect CVE-2024-7553?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If the MongoDB PHP Driver is installed on a monitored server, CVE-2024-7553 will appear in your dashboard with remediation steps.

CVE-2026-39337CVSS 10ChurchCRM is an open-source church management system. Prior to 7.1.0, critical 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 "$dbPassword" variable is not sanitized. This vulnerability exists due to an incomplete fix for CVE-2025-62521. This vulnerability is fixed in 7.1.0.
CVE-2024-5932CVSS 10The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.14.1 via deserialization of untrusted input from the 'give_title' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code remotely, and to delete arbitrary files.
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-2025-62521CVSS 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.
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.
