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 · scopedAspera Faspex 4.4.3 or later
- 1. Back up the current Aspera Faspex configuration and database.
- 2. Review IBM Aspera Faspex 4.4.3 release notes for any prerequisites or migration considerations.
- 3. Download Aspera Faspex version 4.4.3 or later from the official IBM Aspera download portal.
- 4. Stop the Aspera Faspex services before applying the upgrade.
- 5. Install the upgrade following the IBM installation documentation for your platform.
- 6. After installation, verify the XML parser configuration has been updated to prevent external entity injection.
- 7. Start the Aspera Faspex services and confirm normal operation.
- 8. Test that authenticated users can use Faspex normally and that the XML input vulnerability is mitigated.
