CVE-2025-25728
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 · uneditedBosscomm IF740 Firmware versions:11001.7078 & v11001.0000 and System versions: 6.25 & 6.00 were discovered to send communications to the update API in plaintext, allowing attackers to access sensitive information via a man-in-the-middle attack.
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 Bosscomm IF740 firmware versions 11001.7078 and v11001.0000 (System versions 6.25 and 6.00) transmit update API communications in plaintext (unencrypted HTTP), enabling attackers positioned on the network path to intercept sensitive information through man-in-the-middle 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.
-
Identify the device model and firmware versionAccess the Bosscomm IF740 device management interface or use SNMP/CLI commands to retrieve the system model and current firmware version (e.g., 'show version' or check /proc/version if accessible via debug).Affected if The firmware version is 11001.7078 or v11001.0000, or falls within the System versions 6.25 or 6.00 range.
-
Verify if update API endpoint uses HTTPSExamine the device configuration or web interface for the update API endpoint URL. Check if the URL begins with 'http://' (plaintext) or 'https://' (encrypted).Affected if The update API endpoint is configured with 'http://' instead of 'https://'.
-
Inspect network traffic during update operationsUse a network packet capture tool (such as tcpdump or Wireshark) on the network segment between the device and the update server. Initiate a firmware update check and observe the protocol used.Affected if Update API communications are transmitted in plaintext HTTP (port 80) rather than encrypted HTTPS (port 443).
-
Check for TLS/SSL configuration on update moduleReview the device configuration files or web UI settings for the firmware update module. Look for TLS, SSL, or certificate validation settings related to update communications.Affected if TLS/SSL encryption is disabled or not configured for the update API, or certificate validation is disabled.
A user is affected if their Bosscomm IF740 firmware version is 11001.7078 or v11001.0000 (System 6.25 or 6.00) AND the update API communications are transmitted over plaintext HTTP rather than encrypted 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 dataImplement TLS/SSL encryption (HTTPS) for all update API communications and ensure proper certificate validation to prevent plaintext transmission and MITM attacks.
