Malware error on imageupload.php wsx5pro 2021.3.2 and php 7.3.27 
Автор: Peter W.On one of my websites, ImunifyAV keeps identifying malware in imageupload.php and all similar files like /en/res/imageupload_bkgct2md.php (there are 129 such files on my website).
I read other messages that said this was a problem with earlier WSX5 versions and PHP less than 7.3 so I checked both and deleted all those imageupload.php files from my server and did a full upload of my website from WSX5 Pro 2021.3.2
A new scan of those files continues to mark them as malware with the signature-ID: SMW-INJ-13187-php.tool.upld-6
The website in question is https://stnv.de/en
The imageupload.php file is 130 bytes with these contents:
<?php
if (is_uploaded_file($_FILES['file']['tmp_name'])) {
echo base64_encode(file_get_contents($_FILES['file']['tmp_name']));
}
I enclose a screenshot of the error messages.
Hello.I think this is a false positive from the antivirus.You can ignore this.
I sent a notification about your question to the company employees, expect an answer from them here in the comments.
Hello Peter
I can confirm what Aleksej mentioned. This is most certainly a false positive. As of now, we received no similar reports so believe you can safely ignore this
Thank you for your feedback nonetheless
