CVE-2021-46660
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 · uneditedSigniant Manager+Agents before 15.1 allows XML External Entity (XXE) attacks.
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 confidenceSigniant Manager+Agents before version 15.1 contains an XML External Entity (XXE) injection vulnerability that allows attackers to exploit how the application parses XML input. This can enable unauthorized file access, server-side request forgery (SSRF), or denial of service by injecting malicious external entity references into XML documents processed by the application.

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 Signiant Manager+Agents installationLocate the Signiant installation directory and look for version information files, or run the product's version command if available (commonly 'signiant -version' or check product documentation for version retrieval)Affected if Cannot determine version or version is missing from output
-
Verify installed version numberCompare your found version against the affected range: any version below 15.1 (e.g., 15.0.x, 14.x, 13.x) is within the vulnerable rangeAffected if Installed version is less than 15.1 (e.g., 15.0, 14.x, 13.x)
-
Confirm XML processing is in useReview configuration files or logs for XML input processing, or identify if the Signiant Manager handles configuration files, job definitions, or data transfers that use XML formatAffected if Application processes any XML-based configuration or job definitions
If Signiant Manager+Agents version is below 15.1 and processes XML input, the environment is vulnerable to XXE injection.

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.
dbcve · scoped15.1
Upgrade Signiant Manager+Agents to version 15.1 or later to remediate this XXE vulnerability. Additionally, disable XML external entity processing in XML parsers where possible as a defense-in-depth measure.
15.1
- Review the Signiant Manager+Agents upgrade documentation at help.signiant.com or www.signiant.com for version 15.1
- Ensure you have a complete backup of your current configuration and data
- Download the Signiant Manager+Agents version 15.1 or later from the official Signiant download portal
- Follow the standard Signiant upgrade procedure for your platform
- Verify the upgrade was successful and the Manager+Agents services are running
- Confirm the XML parser is no longer vulnerable to XXE attacks
