Unrestricted Upload of File with Dangerous Type

The Hytale Modding Wiki is a free service for Hytale mods to host their documentation & wikis. In version 1.2.0 and prior, the quickUpload() endpoint validates uploaded files by checking their MIME type (via PHP's finfo, which inspects file contents) but constructs the stored filename using the client-supplied file extension from getClientOriginalExtension(). These two checks are independent: an attacker can upload a file whose content passes the MIME allowlist while using a .php extension. The file is stored on the public disk and is directly accessible via URL, allowing server-side code execution. At time of publication no known patches exist.Show less

A vulnerability was detected in Harvard University IQSS Dataverse up to 6.8. This affects an unknown function of the file /ThemeAndWidgets.xhtml of the component Theme Customization. Performing a manipulation of the argument uploadLogo results in unrestricted upload. Remote exploitation of the attack is possible. The exploit is now public and may be used. Upgrading to version 6.10 mitigates this issue. You should upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.Show less

A vulnerability has been found in SourceCodester Simple Doctors Appointment System up to 1.0. This issue affects some unknown processing of the file /doctors_appointment/admin/ajax.php?action=save_category. Such manipulation of the argument img leads to unrestricted upload. The attack may be performed from remote. The exploit has been disclosed to the public and may be used.Show less

baserCMS is a website development framework. Prior to version 5.2.3, the application's restore function allows users to upload a .zip file, which is then automatically extracted. A PHP file inside the archive is included using require_once without validating or restricting the filename. An attacker can craft a malicious PHP file within the zip and achieve arbitrary code execution when it is included. This issue has been patched in version 5.2.3.Show less

A flaw has been found in PromtEngineer localGPT up to 4d41c7d1713b16b216d8e062e51a5dd88b20b054. The affected element is the function do_POST of the file backend/server.py. This manipulation causes unrestricted upload. The attack is possible to be carried out remotely. The exploit has been published and may be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The vendor was contacted early about this disclosure but did not respond in any way.Show less

Bludit’s API plugin allows an authenticated attacker with a valid API token to upload files of any type and extension without restriction, which can then be executed, leading to Remote Code Execution. This issue was fixed in 3.18.4.Show less

Sharp is a content management framework built for Laravel as a package. Versions prior to 9.20.0 contain a vulnerability in the file upload endpoint that allows authenticated users to bypass all file type restrictions. The upload endpoint within the `ApiFormUploadController` accepts a client-controlled `validation_rule` parameter. This parameter is directly passed into the Laravel validator without sufficient server-side enforcement. By intercepting the request and sending `validation_rule[]=file`, an attacker can completely bypass all MIME type and file extension restrictions. This issue has been addressed in version 9.20.0 by removing the client-controlled validation rules and strictly defining upload rules server-side. As a workaround, ensure that the storage disk used for Sharp uploads is strictly private. Under default configurations, an attacker cannot directly execute uploaded PHP files unless a public disk configuration is explicitly used.Show less

A vulnerability was determined in itsourcecode Free Hotel Reservation System 1.0. The affected element is an unknown function of the file /admin/mod_amenities/index.php?view=add. This manipulation of the argument image causes unrestricted upload. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.Show less

plank/laravel-mediable through version 6.4.0 can allow upload of a dangerous file type when an application using the package accepts or prefers a client-supplied MIME type during file upload handling. In that configuration, a remote attacker can submit a file containing executable PHP code while declaring a benign image MIME type, resulting in arbitrary file upload. If the uploaded file is stored in a web-accessible and executable location, this may lead to remote code execution. At the time of publication, no patch was available and the vendor had not responded to coordinated disclosure attempts.Show less

A vulnerability was identified in kalcaddle kodbox 1.64. This issue affects the function Add of the file app/controller/explorer/userShare.class.php of the component Public Share Handler. Such manipulation leads to unrestricted upload. The attack can be executed remotely. This attack is characterized by high complexity. The exploitability is assessed as difficult. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less
