CVE-2021-27481

Sensitive-data disclosure via hard-coded exchange key

Published Jun 16, 2021 · Updated Aug 3, 2024

Use of a hard-coded key in ZOLL Defibrillator Dashboard before 2.2 allows local users to read sensitive data from exchanges. The data-exchange process relies on a cryptographic key embedded in the product instead of protecting it outside the application. Exploitation requires local low-privilege access and affects confidentiality only; public sources do not identify the key's storage location or protected fields.
