CVE-2019-17087
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 · uneditedUnauthorized file download vulnerability in all supported versions of Micro Focus AcuToWeb. The vulnerability could be exploited to enumerate and download files from the filesystem of the system running AcuToWeb, with the privileges of the account AcuToWeb is running under.
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 confidenceUnauthorized file download vulnerability in Micro Focus AcuToWeb that allows attackers to enumerate and download arbitrary files from the server filesystem through insufficient access controls, likely path traversal. The impact is limited to the filesystem permissions of the account running the AcuToWeb service.

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 AcuToWeb is installedCheck common installation directories for AcuToWeb: Windows default is C:\Program Files\Micro Focus\AcuToWeb or C:\Micro Focus\AcuToWeb. On Linux, check /opt/MicroFocus/AcuToWeb or /opt/acutoweb. Look for the acutoweb.exe or acutoweb binary, or check for Micro Focus services running on common ports (8080, 8081).Affected if AcuToWeb software is present on the system and the service is installed.
-
Determine installed AcuToWeb versionCheck the installed version through Windows Programs and Features, or look for a version file in the installation directory (often named version.txt, README, or in the bin directory). If the web interface is accessible, the version may be displayed on the login page or in HTTP headers.Affected if The installed version is lower than 10.3.
-
Verify AcuToWeb service is running and accessibleCheck if the AcuToWeb service process is active. On Windows, use Services.msc or 'sc query AcuToWeb'. On Linux, use 'ps aux | grep acutoweb' or check for the service process. Confirm the web port is listening (commonly 8080 or 8081) using netstat or ss.Affected if The AcuToWeb service is running and accepting network connections.
-
Check filesystem permissions on the service accountReview the user account under which the AcuToWeb service runs. On Windows, right-click the service in Services.msc and check 'Log On As'. On Linux, check the service init script or systemd unit file for the user directive. Verify what filesystem paths that account can access.Affected if The service runs with elevated privileges or has broad filesystem access beyond its application directory.
You are affected if AcuToWeb is installed with a version lower than 10.3 and the service is accessible over the network, as the path traversal flaw can be exploited to read arbitrary files within the service account's filesystem permissions.

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 data10.3
Apply the vendor patch from Micro Focus immediately and verify that AcuToWeb runs with minimal necessary filesystem permissions to limit exposure.
