Security Advisory SB-2025-02: Recording Cards

Published: 2025-10

CVSS Severity: 4.6

Summary

A vulnerability has been identified that may allow bypassing the authentication mechanism of iShield Archive and iShield Camera cards.

An adversary with local or physical access could potentially read out data from the storage, circumventing the PIN / SO-PIN login mechanism.

This vulnerability does not allow data modification or deletion.

Affected Feature

  • Data protection (confidentiality) feature only.
  • Data modification, overwriting, or erasure cannot be performed using this vulnerability.

Not Affected Features

  • The PIN / SO-PIN mechanism itself (authentication logic) is unaffected.
