CWE-434

The WordPress Simple Ecommerce Shopping Cart Plugin- Sell products through Paypal plugin through 2.2.5 does not check for the uploaded Downloadable Digital product file, allowing any file, such as PHP to be uploaded by an administrator. Furthermore, as there is no CSRF in place, attackers could also make a logged admin upload a malicious PHP file, which would lead to RCE

The Email Artillery (MASS EMAIL) WordPress plugin through 4.1 does not properly check the uploaded files from the Import Emails feature, allowing arbitrary files to be uploaded. Furthermore, the plugin is also lacking any CSRF check, allowing such issue to be exploited via a CSRF attack as well. However, due to the presence of a .htaccess, denying access to everything in the folder the file is uploaded to, the malicious uploaded file will only be accessible on Web Servers such as Nginx/IIS

The shopp_upload_file AJAX action of the Shopp WordPress plugin through 1.4, available to both unauthenticated and authenticated user does not have any security measure in place to prevent upload of malicious files, such as PHP, allowing unauthenticated users to upload arbitrary files and leading to RCE

The Workreap WordPress theme before 2.2.2 AJAX actions workreap_award_temp_file_uploader and workreap_temp_file_uploader did not perform nonce checks, or validate that the request is from a valid user in any other way. The endpoints allowed for uploading arbitrary files to the uploads/workreap-temp directory. Uploaded files were neither sanitized nor validated, allowing an unauthenticated visitor to upload executable code such as php scripts.

The Fancy Product Designer WordPress plugin before 4.6.9 allows unauthenticated attackers to upload arbitrary files, resulting in remote code execution.

The Autoptimize WordPress plugin before 2.7.8 attempts to delete malicious files (such as .php) form the uploaded archive via the “Import Settings” feature, after its extraction. However, the extracted folders are not checked and it is possible to upload a zip which contained a directory with PHP file in it and then it is not removed from the disk. It is a bypass of CVE-2020-24948 which allows sending a PHP file via the “Import Settings” functionality to achieve Remote Code Execution.
