CVE-2018-6500
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 · uneditedA potential Directory Traversal Security vulnerability has been identified in ArcSight Management Center (ArcMC) in all versions prior to 2.81. This vulnerability could be remotely exploited to allow Directory Traversal.
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 confidenceDirectory Traversal vulnerability in ArcSight Management Center (ArcMC) allows remote attackers to access files outside the web root directory via manipulation of file paths in HTTP requests. All versions prior to 2.81 are affected.

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 ArcMC versionAccess the ArcSight Management Center web interface and navigate to the About or System Information page, or use the command line interface if available to retrieve the product version numberAffected if The installed version is lower than 2.81 (e.g., 2.7, 2.5, etc.)
-
Verify web interface accessibilityDetermine if the ArcMC web interface (typically on port 8443 or 8080) is exposed to network access beyond trusted networksAffected if The web interface is externally accessible or accessible from untrusted networks, enabling remote exploitation of the directory traversal flaw
-
Review HTTP request handlingExamine web server configuration or proxy logs for any directory traversal patterns in HTTP requests (e.g., ../../etc/passwd)Affected if Such patterns are present in logs or the application accepts path traversal sequences without proper validation
A system is affected if ArcSight Management Center is installed with a version number less than 2.81 and its web interface is accessible to potential attackers.

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 data2.81
Upgrade ArcSight Management Center to version 2.81 or later to remediate this vulnerability. If immediate upgrade is not possible, implement web application firewall rules to block directory traversal patterns in HTTP requests.
