CVE-2025-59703Public exploit

Undetected chassis access via removable tamper label

Published Dec 2, 2025 · Updated Aug 26, 2026

Physical security bypass in Entrust nShield HSM appliances 13.6.11 and earlier or 13.7 allows physically proximate attackers to open them undetected. Isopropanol dissolves the tamper label adhesive without activating its tamper markings, allowing the label and all fixing screws to be removed without visible damage. Hands-on access and careful manipulation are required; the bypass exposes appliance internals, while the embedded HSM and cryptographic keys remain outside the reported impact.
