Security readout for executives and security teams
Plain-English summary
This flaw affects older Dell endpoint encryption/security software. A low-privileged local user could potentially gain elevated privileges on an affected machine because product permissions were set incorrectly. It is not a remote internet-facing issue, but it matters on shared, high-value, or already-compromised endpoints.
Executive priority
Treat as a moderate endpoint hardening priority. It is unlikely to be a standalone remote breach path, but it can increase attacker privileges after local access, making it important for regulated or high-value workstation fleets.
Technical view
CVE-2020-5358 is a CWE-732 incorrect permissions privilege escalation in Dell Encryption before 10.7 and Dell Endpoint Security Suite before 2.7. CVSS 3.1 is 6.7 with local attack vector, high complexity, low privileges, user interaction, unchanged scope, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to endpoints running affected Dell Encryption or Dell Endpoint Security Suite versions. Systems without local untrusted users or prior foothold are less exposed, but compromised endpoint scenarios increase relevance.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not marked KEV. Exploitation requires local access with low privileges, high complexity, user interaction, and a symbolic link condition described by the CVE record.
Researcher notes
Core evidence supports a local privilege escalation caused by incorrect permissions. The affected product/version details are limited in the provided bundle, with Dell’s advisory as the vendor reference. Do not assume broader Dell products are affected without vendor confirmation.
Mitigation direction
- Upgrade Dell Encryption to version 10.7 or later.
- Upgrade Dell Endpoint Security Suite to version 2.7 or later.
- Review Dell advisory SLN321789 for product-specific remediation guidance.
- Prioritize shared, privileged-user, and high-value endpoint populations.
- Restrict local user access where upgrades cannot happen quickly.
Validation and detection
- Inventory endpoints for Dell Encryption and Dell Endpoint Security Suite installations.
- Identify installed versions below 10.7 or 2.7 respectively.
- Confirm remediated endpoints report fixed or later versions.
- Review relevant product permissions against Dell guidance.
- Track exceptions with owner, compensating controls, and upgrade date.

Incorrect Permission Assignment for Critical Resource
Incorrect Permission Assignment for Critical Resource represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
