Security readout for executives and security teams
Plain-English summary
This vulnerability affects Antenna House DMC HTMLFilter as shipped with MarkLogic 8.0-6. A malicious XLS file can corrupt memory during processing and may allow code execution. Business risk is highest where MarkLogic processes spreadsheet files from external users, partners, or automated ingestion pipelines.
Executive priority
Prioritize remediation for any system that processes untrusted spreadsheets. The issue enables potential code execution, but evidence of active exploitation is not provided. If XLS ingestion is internal-only and tightly controlled, urgency is lower but still warrants planned remediation.
Technical view
CVE-2017-2792 is a heap corruption flaw in the iBldDirInfo functionality of Antenna House DMC HTMLFilter used by MarkLogic 8.0-6. The trigger is a specially crafted XLS file. CVSS 3.0 is 8.3 with network attack vector, high complexity, no privileges, user interaction required, changed scope, and high CIA impact.
Likely exposure
Exposure is likely limited to environments running MarkLogic 8.0-6 with the bundled DMC HTMLFilter and workflows that parse XLS files. Internet-facing upload portals, document conversion services, and partner ingestion jobs increase concern. The provided sources do not identify other affected MarkLogic versions.
Exploitation context
The source bundle supports arbitrary code execution from a malicious XLS file, but not active exploitation. CISA KEV status is false in the provided data. Successful exploitation appears to require the crafted file to be accepted and processed by a vulnerable component.
Researcher notes
Talos describes an exploitable heap corruption in iBldDirInfo triggered by crafted XLS input. The CVSS vector indicates high impact but high attack complexity and required user interaction. The evidence only names DMC HTMLFilter as shipped with MarkLogic 8.0-6, so avoid expanding affected scope without vendor confirmation.
Mitigation direction
- Inventory MarkLogic 8.0-6 deployments and document-processing workflows.
- Check MarkLogic and Antenna House guidance for fixed versions or supported mitigations.
- Restrict XLS ingestion from untrusted users until remediation is confirmed.
- Run vulnerable processing components with least privilege and isolation.
- Limit upload access to authenticated, trusted sources where possible.
Validation and detection
- Confirm whether MarkLogic 8.0-6 is present in production or staging.
- Verify whether DMC HTMLFilter processes XLS files in any workflow.
- Review upload and ingestion logs for untrusted XLS submissions.
- Confirm vendor remediation status before declaring risk accepted.
- Validate controls using benign XLS files only.
