CVE-2020-25845
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 · uneditedMultiple functions of NHIServiSignAdapter failed to verify the users’ file path, which leads to the SMB request being redirected to a malicious host, resulting in the leakage of user's credential.
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 confidenceMultiple functions in NHIServiSignAdapter fail to validate user-supplied file paths, allowing attackers to redirect SMB requests to malicious hosts. This enables credential leakage through SMB relay attacks.

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.
-
Locate Nhiservisignadapter installationSearch the system for files named Nhiservisignadapter or NhiServiSignAdapter, typically found in application directories, Program Files, or service installation pathsAffected if The product is installed on the system
-
Identify installed versionCheck version metadata of the Nhiservisignadapter executable or DLL file, commonly accessed via right-click properties in Windows Explorer or using 'wmic product get name,version' or 'Get-ItemProperty' in PowerShell if installed as Windows softwareAffected if The installed version is 1.0.20.0218 exactly
-
Confirm SMB or file transfer functionality is in useReview application logs, configuration files, or network traffic for evidence that the Nhiservisignadapter is processing file paths or making SMB connections to remote hostsAffected if The application is actively handling file paths or initiating SMB requests to external servers
-
Inspect SMB connection configurationExamine Nhiservisignadapter configuration files or registry keys for settings that control remote file path handling or SMB server destinationsAffected if Configuration allows user-supplied or configurable remote file paths that could be redirected to untrusted SMB hosts
A user is affected if Panorama Project Nhiservisignadapter version 1.0.20.0218 is installed and the SMB or file path handling functionality is being used, allowing potential redirection of SMB requests to malicious hosts.

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 path validation and server whitelisting to ensure SMB requests cannot be redirected to untrusted hosts, combined with credential handling review.
