CVE-2023-3761
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 was found in Intergard SGS 8.7.0 and classified as problematic. Affected by this issue is some unknown functionality of the component Password Change Handler. The manipulation leads to cleartext transmission of sensitive information. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. VDB-234446 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceThe Password Change Handler in Intergard SGS 8.7.0 transmits user passwords in cleartext (unencrypted HTTP) rather than using encrypted channels. This allows network eavesdroppers to intercept sensitive authentication credentials as they traverse the network.

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 installed product versionLocate and verify the installed version of Intergard Smartgard Silver With Matrix Keyboard in the system inventory, about screen, or version information panelAffected if The installed version is 8.7.0
-
Identify password change handler endpointLocate the configuration or documentation that defines the password change handler URL/endpoint within the Intergard SGS applicationAffected if The handler is configured to use HTTP (port 80) rather than HTTPS (port 443)
-
Inspect web server configurationExamine the web server or application server configuration files for the Intergard SGS application to determine which ports and protocols are enabled for authentication-related endpointsAffected if The password change endpoint is accessible over unencrypted HTTP
-
Verify SSL/TLS is enforcedCheck whether the application enforces SSL/TLS for all authentication endpoints including the password change handler, or if it allows fallback to unencrypted connectionsAffected if SSL/TLS is not required or is optional for credential transmission
-
Capture test network trafficIf authorized, initiate a password change and capture the network traffic to observe whether the credentials are transmitted in plaintextAffected if Passwords are sent in cleartext over HTTP
The environment is affected if Intergard Smartgard Silver With Matrix Keyboard version 8.7.0 is running and the password change handler is accessible over unencrypted HTTP instead of requiring HTTPS.

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 dataEnable TLS/SSL encryption for the Password Change Handler and ensure all authentication endpoints require HTTPS. Verify that the application enforces encrypted connections for credential transmission.
