CVE-2020-14501
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 · uneditedAdvantech iView, versions 5.6 and prior, has an improper authentication for critical function (CWE-306) issue. Successful exploitation of this vulnerability may allow an attacker to obtain the information of the user table, including the administrator credentials in plain text. An attacker may also delete the administrator account.
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 · high confidenceAdvantech iView versions 5.6 and prior contains a critical authentication bypass (CWE-306) that allows unauthenticated attackers to access the user table and retrieve administrator credentials in plain text. Attackers can also delete administrator accounts, achieving full compromise of the application's authentication system.

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 iView versionLocate the iView application version through the software's About page, installation directory, or version file typically found in the application installation folder. Common locations include the help menu, a version.info file, or the Windows Programs and Features entry.Affected if The installed version is 5.6 or any version number lower than 5.6
-
Verify network exposure of iView interfaceDetermine if the iView web interface is accessible from untrusted networks or the public internet. Check firewall rules, NAT configurations, and reverse proxy settings that expose port 8080, 8443, or the default HTTP/HTTPS ports used by iView.Affected if The iView application is accessible to unauthenticated users on the network without VPN or network segmentation restrictions
-
Inspect authentication mechanismReview the application's authentication configuration files and settings to confirm whether the built-in authentication mechanism is enabled and functioning. Check if the login page at the default iView URL is responding normally.Affected if The authentication bypass allows accessing user management functions without valid credentials, or the user table endpoint is accessible without authentication
A system is affected if it runs Advantech iView version 5.6 or lower and the application interface is accessible to unauthenticated network attackers.

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 · scopedUpgrade Advantech iView to a version greater than 5.6. If immediate patching is not possible, implement compensating controls such as network segmentation, WAF rules, and严密监控 for suspicious activity targeting the iView interface.
Advantech iView version > 5.6 (contact vendor for latest stable release)
- 1. Identify the current Advantech iView version running in your environment
- 2. Download the latest version of Advantech iView from the official Advantech support website (support.advantech.com)
- 3. Review the release notes for the new version to confirm security fixes are included
- 4. Create a full backup of the current iView installation and database
- 5. Test the upgrade in a non-production environment before deploying to production
- 6. Deploy the upgraded version to production environment
- 7. Verify the upgrade was successful and all services are running
- 8. Confirm the administrator account is accessible with correct credentials
