CVE-2016-8211
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 · uneditedEMC Data Protection Advisor 6.1.x, EMC Data Protection Advisor 6.2, EMC Data Protection Advisor 6.2.1, EMC Data Protection Advisor 6.2.2, EMC Data Protection Advisor 6.2.3 prior to patch 446 has a path traversal vulnerability that may potentially be exploited by malicious users to compromise the affected system.
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 confidenceEMC Data Protection Advisor versions 6.1.x through 6.2.3 contain a path traversal vulnerability that allows attackers to access files outside the web root folder using '../' sequences in user-supplied input. This can expose sensitive system files or potentially enable code execution depending on the application's file handling behavior.

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.
-
Identify if EMC Data Protection Advisor is installedCheck installed programs or application inventory for DPA. Common locations include /opt/emc/dpa or C:\Program Files\EMC\Data Protection Advisor on Windows systems. Look for the DPA application.Affected if DPA software is found on the system
-
Determine the installed DPA versionLocate the DPA version information - typically found in an about page within the DPA web interface, a version file in the installation directory, or the Windows registry under the DPA installation key.Affected if Version is 6.1.x, 6.2, 6.2.1, 6.2.2, or 6.2.3
-
Check if the DPA web interface is accessibleVerify if the DPA web service is running and reachable. Common default ports are 9002 or 8443. Attempt to access the login page via HTTP/HTTPS.Affected if The DPA web interface is exposed and accepts user input
-
Confirm web root configurationExamine the DPA web server configuration to identify the web root directory and verify if file upload or download features exist that accept user-supplied file paths.Affected if File handling features accept user input without apparent sanitization
The environment is affected if EMC Data Protection Advisor version 6.1 through 6.2.3 is installed and the web interface is accessible, as the path traversal vulnerability exists in user-supplied input handling.

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 dataApply patch 446 which adds proper input validation and sanitization to prevent directory traversal attacks. Until patch deployment, restrict network access to the DPA interface to trusted users only.
