CVE-2018-1211
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 iDRAC7/iDRAC8, versions prior to 2.52.52.52, contain a path traversal vulnerability in its Web server's URI parser which could be used to obtain specific sensitive data without authentication. A remote unauthenticated attacker may be able to read configuration settings from the iDRAC by querying specific URI strings.
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 confidenceA path traversal vulnerability exists in the Dell EMC iDRAC7 and iDRAC8 web server's URI parser. By using specially crafted URI strings with directory traversal sequences (e.g., ../../), an unauthenticated remote attacker can access sensitive configuration files outside the intended web root directory, exposing iDRAC configuration settings without authentication.

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.
-
Determine if iDRAC web interface is network-accessibleFrom an external or management network perspective, attempt to reach the iDRAC web interface (typically ports 443 or 80). Use a browser or curl to confirm the iDRAC login page loads at https://<idrac-ip>Affected if The iDRAC web interface is reachable from untrusted networks (such as the internet or non-management VLANs)
-
Identify iDRAC firmware versionAccess the iDRAC web interface and navigate to the 'iDRAC Settings' > 'Overview' > ' firmware' page, or use the racadm command-line tool: racadm get idrac.firmwareAffected if The displayed firmware version is below 2.52.52.52 for either iDRAC7 or iDRAC8
-
Confirm iDRAC model generationCheck the iDRAC login page banner or the firmware information page for the specific model (iDRAC7 vs iDRAC8). The racadm command 'racadm getsysinfo' also displays the iDRAC modelAffected if The model is identified as iDRAC7 or iDRAC8 and the version is below 2.52.52.52
A system is affected if it runs iDRAC7 or iDRAC8 firmware versions prior to 2.52.52.52 AND the iDRAC web interface is network-accessible, allowing unauthenticated path traversal attacks.

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 data2.52.52.52
Upgrade iDRAC7/iDRAC8 firmware to version 2.52.52.52 or later. If immediate patching is not possible, consider network segmentation to restrict access to the iDRAC management interface to only trusted networks or use out-of-band management.
