Official description
Dell PowerProtect Data Domain with Data Domain Operating System (DD OS) versions prior to 8.3.0.15 contain an Insufficient Granularity of Access Control vulnerability. An authenticated user from a trusted remote client could exploit this vulnerability to execute arbitrary commands with root privileges.
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.
