CVE-2015-4056 Dell CVE debrief

Who should care

Administrators and security teams responsible for Dell VCE Vision Intelligent Operations deployments, especially systems still running version 2.6.4 or earlier. Because the flaw requires local administrative access, it is most relevant where privileged accounts are shared, exposed, or insufficiently controlled.

Technical summary

NVD maps the affected product as Dell VCE Vision Intelligent Operations versions through 2.6.4, with the vulnerable component identified as the System Library. The weakness is a cryptographic implementation problem (CWE-310) that can expose credentials to a local user who already has administrative access. NVD assigns CVSS v3.1 vector AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, reflecting the need for high privileges and a local attack path.

Defensive priority

Medium. The attack requires local administrative privileges, which narrows exposure, but the impact includes credential discovery and high confidentiality/integrity/availability consequences if the issue is reachable in a real environment.

Recommended defensive actions

• Upgrade Dell VCE Vision Intelligent Operations to version 2.6.5 or later, since versions before 2.6.5 are identified as affected.
• Inventory deployments to confirm whether any systems remain on 2.6.4 or earlier.
• Review local administrative access controls and remove unnecessary privileged accounts.
• Rotate credentials if there is any reason to suspect exposure on affected systems.
• Follow vendor and NVD guidance for any additional remediation notes or updates.
