NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA critical unrestricted file upload vulnerability exists in DedeBIZ 6.3.0 where the get_mime_type function in /admin/dialog/select_images_post.php fails to properly validate uploaded files. Remote attackers can manipulate the upload parameter to bypass mime-type checks and upload malicious files to the server.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify DedeBIZ versionLocate the version file or admin panel about page to determine the installed DedeBIZ versionAffected if The installed version is exactly 6.3.0
-
Confirm vulnerable file existsCheck if /admin/dialog/select_images_post.php exists in the webrootAffected if The file select_images_post.php exists and is readable
-
Check admin access to upload endpointVerify the /admin/ path is accessible and the user has admin privileges to access dialog/select_images_post.phpAffected if The admin interface is exposed and authentication can be bypassed or valid admin credentials exist
-
Inspect upload directory configurationExamine the web server configuration and .htaccess to determine where uploaded files are stored and whether script execution is restrictedAffected if Uploaded files are stored within the webroot and script execution is not disabled in the upload directory
A system is affected if it runs DedeBIZ version 6.3.0 with the vulnerable /admin/dialog/select_images_post.php file accessible and uploads stored within the webroot without script execution restrictions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince the vendor did not respond to the disclosure, implement web application firewall rules to restrict upload functionality, limit admin panel access to trusted IPs, and manually patch the select_images_post.php to add proper file type validation and extension allowlisting before deployment.
