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.
-
Detect aaPanel installationLook for aaPanel installation directories such as /www/server/panel or /opt/aaPanel, or check for running panel services using 'ps aux | grep panel'Affected if aaPanel is installed on the system
-
Determine aaPanel versionCheck the version file typically located at /www/server/panel/class/common.py or access the panel web interface and look for the version information in the footer or system settingsAffected if The installed version is exactly 7.57.0
-
Verify file upload functionalityAccess aaPanel settings and check if file upload features are enabled, or inspect configuration files in /www/server/panel/config/ for upload-related settingsAffected if File upload functionality is enabled in the panel
-
Inspect upload directoriesExamine directories where aaPanel stores uploaded files, commonly /www/wwwroot/ or custom upload paths, for unexpected scripts or executable files with extensions like .php, .py, .sh, or .exeAffected if Suspicious or unrecognized script files are present in upload directories
-
Check web root for backdoorsSearch web-accessible directories for newly created or modified files with dangerous extensions, particularly in /www/wwwroot/, using commands like 'find /www/wwwroot/ -type f -name "*.php" -mtime -30'Affected if Recently created PHP or script files are found that were not intentionally deployed
A system is affected if aaPanel version 7.57.0 is installed and file upload functionality is enabled, allowing potential malicious file uploads and code execution.

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 dataUpgrade aaPanel to the latest patched version. If no patch is available, disable the file upload functionality or implement strict file type validation, whitelist allowed extensions, and prevent execution of uploaded files by storing them outside web-accessible directories.
