CVE-2017-20016
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 vulnerability has been found in WEKA INTEREST Security Scanner up to 1.8 and classified as problematic. This vulnerability affects unknown code of the component Portscan. The manipulation with an unknown input leads to denial of service. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. NOTE: This vulnerability only affects products that are no longer supported by the maintainer
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 confidenceA denial of service vulnerability exists in the Portscan component of WEKA INTEREST Security Scanner up to version 1.8. The vulnerability is remotely exploitable via unknown input manipulation, and a public exploit has been disclosed.

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.
-
Confirm Weka Interest Security Scanner is installedCheck for the presence of Weka Interest Security Scanner installation directories or executables on the system. Common locations may include C:\Program Files\Weka or /opt/weka. Also check installed programs list on Windows or package manager on Linux.Affected if The product is found installed on the system
-
Identify installed versionLocate version information in the application's install directory, readme files, or execute the application with version flags (such as --version or -v). Compare the version number to 1.8 or earlier.Affected if The installed version is 1.8 or any version lower than 1.8
-
Verify Portscan component is configuredExamine the application configuration files for Portscan component settings. Look for configuration files in the install directory or application data folder. Check for portscan-related configuration sections or modules.Affected if The Portscan component is enabled or configured in the application
-
Assess network exposure of Portscan serviceReview network bind addresses and firewall rules to determine if the Portscan functionality is accessible over the network. Check if the application listens on external interfaces (0.0.0.0) rather than localhost (127.0.0.1).Affected if The Portscan service is listening on network-accessible interfaces
The environment is affected if Weka Interest Security Scanner version 1.8 or lower is installed with the Portscan component enabled and exposed to network access.

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 dataSince the product is no longer maintained, migrate to an actively supported security scanner solution. If continued use is unavoidable, implement network segmentation and firewall controls to restrict access to the Portscan functionality.
