Unrestricted Upload of File with Dangerous Type in Cdesigner module for PrestaShop
In the module “Cdesigner” (cdesigner) up to 3.2.1 (3.2.2 fix the issue), a guest can upload files with extensions .php.+ (like .php7)
Note : .php extension is correctly block so it will be harmless for most servers’s setups.
Important : If you use default configuration for your server, you should be safe - which should be the case of the majority of servers, so don’t worry too much about this CVE.
We are forced to tag it as critical since it will be critical for some setups, but for the majority, it should be completly harmless.
You can check if you are vulnerable by uploading files with extensions : .php3 / .php4 / .php5 / .php7 / .php8 with this content : <?php echo (21+21); - when you make a HTTP call against theses files, if you do not see 42, all is OK else, you service is vulnerable, contact without delay your hoster.
The method CdesignerSaverotateModuleFrontController::initContent() misuses strpos which can lead to upload .phpX files, depending on your server’s setup, which will lead to a critical vulnerability CWE-94.
This exploit is actively exploited in the wild
WARNING : If your service is vulnerable, be warn that this exploit will bypass some WAF (base64 payloads)
