CVE Database

Webkul QloApps does not perform proper validation on uploaded file extensions or MIME types before moving the file to a publicly accessible directory. A remote, authenticated attacker with administrative privileges could upload executable files and achieve remote code execution. Fixed in 153ec1c.

The CM Map Locations – Visualize and share your locations in a few clicks plugin for WordPress is vulnerable to Limited Arbitrary File Upload in all versions up to, and including, 2.1.8 via the uploadMedia function. This is due to insufficient file type validation in the upload handler, which performs incomplete extension filtering without MIME-type checks or upload capability verification before passing attacker-supplied files to move_uploaded_file(). This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. The required nonce is exposed to any logged-in Subscriber via the CMLOC_Editor_Images JavaScript object on the front-end location editor page.

Adminer versions before 5.4.3 contain an unrestricted file upload vulnerability in the AdminerFileUpload plugin that allows authenticated users to upload PHP files by exploiting a permissive default extension allowlist. Attackers can upload PHP webshells to columns ending in _path and execute arbitrary code as the web-server user when uploadPath is web-served.

ATutor Gameme module allows users to upload files of any type and extension without restriction. Due to improper handling of file uploads, files are stored in a web-accessible location before their content is validated. An authenticated attacker who knows a valid course_id can upload a server-executable malicious script. The uploaded file can then be requested over HTTP, resulting in remote code execution as the web server process user. In most cases, course_id=0 can be used, as it commonly represents the global context. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

A high privileged remote attacker can upload a .php file and then request it directly from /uploads/<filename>.php to achieve arbitrary code execution due to improper file type validation which could result in full system compromise.

The Depicter — Popup & Slider Builder WordPress plugin before 4.8.0 does not validate the type of a file uploaded through its import feature and does not remove a malformed upload, allowing users with editor-level access to write an arbitrary file (including executable PHP) into a web-accessible directory, which can lead to remote code execution.

Wekan is open source kanban built with Meteor. Prior to 9.90, isFileValid() in models/fileValidation.js used the Unix file command for content-based MIME detection, but detectMimeFromFile() silently returned undefined when that binary was unavailable and the validation fell back to the attacker-controlled fileObj.type supplied through server/routes/attachmentApi.js. On deployments with WITH_API=true and no file binary, an authenticated board member could label HTML containing JavaScript as image/png, bypass the dangerous MIME check, and store active content under the Wekan origin for execution when another user opened it. Version 9.90 adds looksLikeDangerousMarkup() to inspect file bytes and force dangerous-content scanning when MIME detection is unavailable. This issue is fixed in version 9.90.
