CVE-2024-39752
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 · uneditedIBM Analytics Content Hub 2.0, 2.1, 2.2, and 2.3 could be vulnerable to malicious file upload by not validating the type of file uploaded to Explore Content. Attackers can make use of this weakness and upload malicious executable files into the system, and it can be sent to victim for performing further attacks.
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 confidenceIBM Analytics Content Hub versions 2.0-2.3 lacks proper file type validation in the Explore Content upload feature, allowing attackers to upload malicious executable files (e.g., .exe, .sh, .bat, .php) without restriction. This unrestricted file upload can lead to remote code execution if uploaded files are accessed via the web server, or enable phishing campaigns by distributing malicious files to victims.

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.
-
Determine IBM Analytics Content Hub versionLocate the product version through the admin console, about page, or installation metadata. Common locations include the system information panel, version.info file, or the /api/system/info endpoint.Affected if Installed version is 2.0, 2.1, 2.2, or 2.3 (versions below 2.4)
-
Verify Explore Content upload feature is accessibleNavigate to the Explore Content section in the web interface and locate the file upload functionality. Confirm the upload interface is available and not disabled.Affected if The Explore Content upload feature is enabled and accessible to users
-
Test upload capability with non-executable fileUpload a benign file (e.g., .txt or .csv) through the Explore Content upload feature to confirm the upload mechanism is functional.Affected if File upload functionality is operational in Explore Content
-
Inspect upload file type restrictionsReview the upload configuration, content-type validation settings, or file extension allowlist for the Explore Content upload feature. Check if .exe, .sh, .bat, .php or other executable extensions are explicitly blocked or only loosely validated.Affected if The upload feature accepts executable file types (.exe, .sh, .bat, .php) or lacks strict allowlist validation
-
Check upload storage location and execution permissionsIdentify where uploaded files are stored (inside or outside web root) and whether script execution is permitted in that directory. Review server configuration for upload folder permissions.Affected if Uploaded files are stored within the web root with execute permissions enabled
A system is affected if it runs IBM Analytics Content Hub version 2.0-2.3, has the Explore Content upload feature enabled, and permits uploading executable file types without strict validation.
Generated from the published advisory. Verify against your own configuration.
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 · scoped2.4
Implement strict allowlist-based file type validation using both MIME type verification and magic byte inspection, store uploads outside web root with no execute permissions, and disable script execution in upload directories.
IBM Analytics Content Hub version 2.4
- Back up all current data, configurations, and uploaded content from the existing Analytics Content Hub installation
- Review IBM Analytics Content Hub upgrade documentation for version 2.4 at www.ibm.com/support/documentation
- Download IBM Analytics Content Hub version 2.4 from IBM Fix Central or authorized distribution channels
- Follow IBM's documented upgrade procedure to install version 2.4, ensuring all prerequisites are met
- After upgrade, verify that file upload functionality in Explore Content now properly validates file types and rejects executable files
- Test that legitimate file types can still be uploaded successfully
- Confirm the vulnerability is remediated by attempting to upload a file with an executable extension (e.g., .exe, .php, .sh) - it should be rejected
