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 · unedited
Incorrect access control in BW Broadcast TX600 (14980), TX300 (32990) (31448), TX150, TX1000, TX30, and TX50 Hardware Version: 2, Software Version: 1.6.0, Control Version: 1.0, AIO Firmware Version: 1.7 allows attackers to access log files and extract session identifiers to execute a session hijacking 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 · moderate confidence

Incorrect access control in BW Broadcast TX series transmitters (TX600, TX300, TX150, TX1000, TX30, TX50) allows unauthenticated attackers to access log files without proper authorization. These log files contain session identifiers that can be extracted to execute session hijacking attacks, compromising user accounts.

MitigationApply vendor firmware update when available. In the interim, restrict network access to the device, implement IP-based access controls, and monitor log endpoint access for suspicious activity.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify BW Broadcast TX series device
    Locate the device model number on the physical unit or in the device's web interface/system information page. Confirm it is one of: TX600, TX300, TX150, TX1000, TX30, or TX50.
    Affected if The device is a BW Broadcast TX series transmitter (any of the listed models).
  2. Check network accessibility of log endpoint
    Attempt to access the device's log file endpoint via HTTP/HTTPS from an unauthenticated context. Common paths may include /logs, /log, /system/logs, or similar. Use a web browser or curl command without providing credentials.
    Affected if Log files are accessible over the network without any authentication required.
  3. Inspect log contents for session identifiers
    If the log endpoint is accessible, examine the returned log data for session tokens, session IDs, cookies, or authentication tokens that could be used for session hijacking.
    Affected if Log files contain session identifiers, authentication tokens, or session cookies.
  4. Verify IP-based access controls are not in place
    Check the device's administrative interface for IP access control lists or firewall rules that restrict log endpoint access to specific IP addresses or ranges.
    Affected if No IP-based access restrictions are configured and the log endpoint is openly accessible on the network.

If the device is a BW Broadcast TX series model with its log endpoint accessible without authentication over the network, the environment is affected by this CVE.
