Techniques & Countermeasures

  • CWE-1220•Insufficient Granularity of Access Control

    The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.

Affected Systems

  • ibm•spectrum fusion hci

    ≥ 2.5.2, ≤ 2.7.2

  • ibm•storage_fusion_hci

    ≥ 2.5.2, < 2.8.0
