CVE Database

H3C CVM, the Cloud Virtualization Management component of the H3C CAS cloud platform, contains an unauthenticated arbitrary file upload vulnerability in the /cas/fileUpload/upload endpoint that allows remote attackers to write arbitrary files by manipulating the caller-supplied token parameter without restricting path traversal or file type. Attackers can exploit the path traversal in the token parameter to upload a malicious JSP file into a web-accessible directory and then request it to achieve remote code execution as the web-server user. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.

Joomla Extension - ordasoft.com - Unauthenticated Remote Code Execution in OrdaSoft Joomla CCK < 8.3.16 - site/uploader.php is reached through the component’s normal frontend routing (task=getContent), a task with no authentication or ACL check anywhere in the dispatch chain. The handler validates the uploaded file’s content with a real magic-byte MIME check, but the extension allow-list that would otherwise restrict the saved file’s extension was present in the source and commented out. The saved file’s extension was taken directly from the attacker-supplied filename with no validation, and the file was written to a path directly under the Joomla web root that is executed by the PHP handler. An image/PHP polyglot, a file whose header bytes satisfy the MIME check with PHP source appended after, passed the content check while carrying a .php extension of the attacker’s choosing.

The Zella Theme WordPress theme before 2.6.3 does not perform any capability or nonce check on one of its font upload actions, which is available to unauthenticated users, allowing them to upload arbitrary files, including PHP ones, and achieve remote code execution.

The TMS file upload endpoint fails to enforce server-side file type restrictions, allowing an attacker to upload and execute arbitrary PHP files on the web server.

Unrestricted Upload of File with Dangerous Type in the /WebAgenda/download/uploadFile.jsp API endpoint of Flowring Agentflow 4.0 version before 2023/03/24 allows remote authenticated users to execute arbitrary system commands via a malicious file.

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Arbitrary File Upload due to insufficient file type validation in the 'uacf7_wpcf7_mail_components' function in all versions up to, and including, 3.5.50. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: This is only exploitable when the plugin's PDF Generator module is enabled, which is disabled by default.

The Request a Quote for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.9.2 via the `afrfq_submit_quote_via_popup()` function. This is due to missing file extension and MIME type validation in the popup upload handler, which uses the raw attacker-supplied filename directly as the destination for `move_uploaded_file()`. This makes it possible for unauthenticated attackers to upload executable files, such as PHP files, to a web-accessible temporary RFQ upload directory when a public quote rule with the multi-page popup flow is enabled.

Piwigo is a full featured open source photo gallery application for the web. Prior to 16.4.0, admin/themes_standard_pages.php validates uploaded logo content by MIME type but reuses the attacker-controlled extension from std_pgs_logo when constructing the stored filename. An authenticated administrator can upload image content with a server-executable final extension, causing the file to be placed in the web-accessible logo directory and executed when requested if the web server handles that extension. This can permit arbitrary command execution, data disclosure, modification, persistence, and service disruption. This vulnerability is fixed in 16.4.0.

Laravel-Mediable 7.0.0 before 7.0.2 contains an incomplete patch for CVE-2026-49972 in which the .pht extension is absent from the forbidden_extensions blocklist in config/mediable.php. The blocklist introduced to address CVE-2026-49972 includes phpt but omits pht, which Apache executes as PHP via the default FilesMatch directive on Debian and Ubuntu systems. An attacker can upload a .pht file that passes all validation in MediaUploader::verifyExtension() and File::sanitizeFileName() because pht is not present in the blocklist, causing the file to be written to disk and executed as PHP when requested, enabling remote code execution with the privileges of the web server process.
