CVE-2024-57728
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSimpleHelp remote support software v5.5.7 and before allows admin users to upload arbitrary files anywhere on the file system by uploading a crafted zip file (i.e. zip slip). This can be exploited to execute arbitrary code on the host in the context of the SimpleHelp server user.
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 confidenceSimpleHelp versions 5.5.7 and earlier contain a zip slip vulnerability allowing authenticated admin users to upload crafted ZIP archives containing paths with directory traversal sequences (e.g., ../../../). During extraction, the server writes files to arbitrary filesystem locations instead of the intended directory, enabling remote code execution in the context of the SimpleHelp server user.

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.
-
Identify SimpleHelp installation and versionCheck the web interface footer or login page for the version number, or inspect the SimpleHelp server configuration files for the installed version string.Affected if The displayed version is 5.5.7 or any version prior to 5.5.8.
-
Confirm admin authentication is enabledVerify that the SimpleHelp admin interface requires authentication. Check if the /admin endpoint or equivalent admin login page is accessible and protected by credentials.Affected if Admin authentication is not enforced or the admin panel is publicly accessible without login.
-
Determine if file upload is available to adminsLog into the admin interface and navigate to the file transfer or upload feature (typically under customer/session management or file sharing sections). Verify whether a feature exists that allows authenticated admins to upload zip archives.Affected if The admin interface includes a zip or file upload feature that can be used by authenticated administrators.
-
Check for signs of exploitationReview server logs for suspicious path traversal patterns in uploaded filenames (such as entries containing ../ sequences). Inspect filesystem directories outside the intended upload root for unexpected SimpleHelp-related files.Affected if Log entries or filesystem anomalies indicate that zip files with traversal sequences have been processed by the server.
You are affected if SimpleHelp version is below 5.5.8 and the admin interface with file upload capability is accessible to authenticated administrators.

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.
dbcve · scoped5.5.8
Upgrade to SimpleHelp version newer than 5.5.7 which includes proper path validation during archive extraction. If immediate patching is not possible, restrict administrative access and implement file upload monitoring/filtering.
5.5.8
- 1. Back up the current SimpleHelp installation and all configuration data
- 2. Download SimpleHelp version 5.5.8 or later from the official vendor source (simple-help.com)
- 3. Stop the SimpleHelp service
- 4. Upgrade SimpleHelp to version 5.5.8 or later following the vendor's upgrade documentation
- 5. Restart the SimpleHelp service
- 6. Verify the upgrade was successful and the service is running properly
