CVE-2019-11655
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 · uneditedUnrestricted file upload vulnerability in Micro Focus ArcSight Logger, version 6.7.0 and later. This vulnerability could allow Unrestricted Upload of File with Dangerous type.
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 · moderate confidenceUnrestricted file upload vulnerability in Micro Focus ArcSight Logger versions 6.7.0 and later allows attackers to upload files with dangerous types, potentially leading to remote code execution if malicious files (e.g., web shells) are uploaded and subsequently executed.

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 installed ArcSight Logger versionAccess the product admin console or run the version retrieval command specific to ArcSight Logger (typically via the management interface or product-specific CLI tool). Locate the version number displayed in the about or system information section.Affected if The installed version is 6.7.0 or any later version (6.7.0, 6.8.0, 6.9.0, etc.)
-
Confirm web-based upload functionality is exposedIdentify if the ArcSight Logger web interface (typically on ports 443, 8443, or configured HTTP ports) is accessible from the network. Check whether upload-related endpoints are available without authentication or with low-privileged user access.Affected if The web interface with file upload capability is externally accessible or accessible to untrusted users
-
Inspect file upload security configurationReview the ArcSight Logger configuration files or admin settings related to file uploads. Look for settings that control allowed file types, file size limits, filename handling, and upload destination paths.Affected if No allowlist-based file type validation, no magic byte verification, and uploads are stored within the web root or accessible directory
You are affected if your ArcSight Logger version is 6.7.0 or higher AND the file upload feature is accessible without proper validation controls in place.

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 dataImplement strict file upload validation including allowlist-based file type checking, file content magic byte verification, filename sanitization, size limits, and storing uploads outside the web root with randomized filenames.
