CVE-2024-10439
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 · uneditedThe eHRD CTMS from Sunnet has an Insecure Direct Object Reference (IDOR) vulnerability, allowing unauthenticated remote attackers to modify a specific parameter to access arbitrary files uploaded by any 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 · moderate confidenceThe eHRD CTMS from Sunnet contains an Insecure Direct Object Reference (IDOR) vulnerability that allows unauthenticated remote attackers to access arbitrary files uploaded by any user by modifying a specific parameter. This is a high-severity access control flaw enabling unauthorized file access without authentication.

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 if Sunnet eHRD CTMS is installedCheck your web applications and server for the presence of eHRD CTMS. Look for application directories, service names, or web accessible paths that contain 'eHRD', 'ctms', or 'sunnet' in the name.Affected if The application is present on the system
-
Check the installed eHRD CTMS versionLocate the version information for the installed eHRD CTMS instance. This is typically found in the application properties file, about page, or in the deployment descriptors. Compare your version against the affected range of versions prior to 10.8.Affected if The installed version is earlier than 10.8
-
Verify the file upload module is accessibleIdentify if the web interface exposes a file upload or file download functionality. Check for endpoints that handle file retrieval or viewing of previously uploaded documents within the CTMS application.Affected if The file upload/download module is web-accessible
-
Test unauthenticated file access via parameter manipulationIf the file access feature exists, attempt to access files by modifying the parameter that references uploaded files. Try changing user identifiers or file references in the request to access files belonging to different users without providing credentials.Affected if Unauthenticated users can access files belonging to other users by manipulating request parameters
A user is affected if they have Sunnet eHRD CTMS version earlier than 10.8 running with the web-accessible file upload feature that allows unauthenticated access to other users' uploaded files via parameter manipulation.

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 · scoped10.8
Implement proper authorization checks to validate that requesting users have permission to access specific files, and add validation to ensure the parameter cannot be manipulated to access files outside the user's authorized scope.
eHRD CTMS version 10.8
- 1. Obtain the latest version of eHRD CTMS (version 10.8 or later) from the vendor (Sunnet)
- 2. Review the vendor's release notes and upgrade documentation for version 10.8
- 3. Perform a full backup of the current eHRD CTMS installation and database
- 4. Test the upgrade in a staging environment before deploying to production
- 5. Deploy the upgrade to production following vendor-recommended procedures
- 6. Verify that the IDOR vulnerability is remediated by attempting to access files through unauthorized parameter manipulation
