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
An authentication bypass issue was discovered in Dasan Switch DS2924 web based interface, firmware versions 1.01.18 and 1.02.00, allowing attackers to gain escalated privileges via storing crafted cookies in the web browser.

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

The Dasan Switch DS2924 web interface in firmware versions 1.01.18 and 1.02.00 contains an authentication bypass vulnerability where attackers can gain escalated privileges by storing crafted cookies in the web browser. This allows unauthorized access to the switch management interface without proper credentials.

MitigationApply vendor firmware patches when available. In the interim, restrict web management interface access to trusted IP addresses only via ACLs and monitor for suspicious cookie-based authentication attempts.

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 the switch model
    Access the device CLI or web interface and confirm the model number is DS2924. Check the device status page or system information page for the model designation.
    Affected if The device is not a Dasan Switch DS2924 model.
  2. Check the installed firmware version
    In the web interface, navigate to System > Firmware or System > Status to view the current firmware version. Alternatively, use the CLI command 'show version' or 'show system-info' to retrieve the firmware build number.
    Affected if The firmware version is exactly 1.01.18 or exactly 1.02.00.
  3. Verify the web management interface is enabled
    In the web interface, go to Management > Web or Administration > HTTP/HTTPS settings. Confirm the HTTP or HTTPS management service is turned on and accessible.
    Affected if The web management interface is disabled or not accessible.
  4. Confirm web interface is network accessible
    Attempt to reach the web interface via HTTP/HTTPS from an external location or check the network accessibility settings in Management > Access Control. Verify the interface is not restricted to trusted IPs only.
    Affected if The web management interface is exposed to untrusted networks.

You are affected if you have a Dasan DS2924 switch running firmware version 1.01.18 or 1.02.00 with the web management interface enabled and accessible.
