CVE-2018-11078
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell EMC VPlex GeoSynchrony, versions prior to 6.1, contains an Insecure File Permissions vulnerability. A remote authenticated malicious user could read from VPN configuration files on and potentially author a MITM attack on the VPN traffic.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDell EMC VPlex GeoSynchrony versions prior to 6.1 contain insecure file permissions on VPN configuration files. A remote authenticated attacker can read these files to obtain VPN credentials, certificates, and connection details, enabling potential MITM attacks on VPN traffic.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed VPlex GeoSynchrony versionRun the command to display the Dell EMC VPlex GeoSynchrony version (for example, via the management interface or system information command). Compare the version number to the affected range (versions prior to 6.1).Affected if The installed version is below 6.1 (for example, 6.0.x or earlier)
-
Locate VPN configuration filesIdentify VPN configuration files on the VPlex system. These files typically contain VPN credentials, certificates, and connection details. Common locations may include configuration directories or VPN-specific paths on the system.Affected if VPN configuration files exist on the system and the VPlex version is below 6.1
-
Inspect file permissions on VPN configuration filesUse file system commands (such as ls -la or icacls) to examine the permissions on identified VPN configuration files. Check for overly permissive access controls that allow unauthorized users to read these files.Affected if VPN configuration files have permissions that allow read access to users other than the intended administrator or service account (for example, world-readable or group-readable permissions)
A system is affected if it runs Dell EMC VPlex GeoSynchrony version prior to 6.1 AND has VPN configuration files with insecure file permissions that could be read by unauthorized users.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data6.1
Upgrade Dell EMC VPlex GeoSynchrony to version 6.1 or later to remediate the insecure file permissions. If immediate upgrade is not feasible, restrict filesystem access to VPN configuration files and implement monitoring for unauthorized access attempts.
