Official description

Dell PowerProtect DD, versions prior to 7.13.0.10, LTS 7.7.5.25, LTS 7.10.1.15, 6.2.1.110 contain an improper access control vulnerability. A local malicious user with low privileges could potentially exploit this vulnerability leading to escalation of privilege.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: 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 the required granularity

How developers prevent this class of flaw

  • Access-control-policy protections must be reviewed for design inconsistency and common weaknesses. Access-control-policy definition and programming flow must be tested in pre-silicon, post-silicon testing.
