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
Cross-site request forgery (CSRF) vulnerability exists in FURUNO SYSTEMS wireless LAN access point devices. If a user views a malicious page while logged in, unintended operations may be performed. Affected products and versions are as follows: ACERA 1210 firmware ver.02.36 and earlier, ACERA 1150i firmware ver.01.35 and earlier, ACERA 1150w firmware ver.01.35 and earlier, ACERA 1110 firmware ver.01.76 and earlier, ACERA 1020 firmware ver.01.86 and earlier, ACERA 1010 firmware ver.01.86 and earlier, ACERA 950 firmware ver.01.60 and earlier, ACERA 850F firmware ver.01.60 and earlier, ACERA 900 firmware ver.02.54 and earlier, ACERA 850M firmware ver.02.06 and earlier, ACERA 810 firmware ver.03.74 and earlier, and ACERA 800ST firmware ver.07.35 and earlier. They are affected when running in ST(Standalone) mode.

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 confidence

CSRF vulnerability in FURUNO SYSTEMS ACERA wireless LAN access point web interfaces. When an authenticated administrator views a malicious webpage, the attacker's site can silently trigger unauthorized operations on the affected AP's admin interface by leveraging the active session, allowing configuration changes or device manipulation without the user's consent.

MitigationUpdate firmware to versions beyond those specified (ACERA 1210: >02.36, ACERA 1150i/1150w: >01.35, ACERA 1110: >01.76, ACERA 1020/1010: >01.86, ACERA 950/850F: >01.60, ACERA 900: >02.54, ACERA 850M: >02.06, ACERA 810: >03.74, ACERA 800ST: >07.35) while operating in ST (Standalone) mode. Until patched, avoid browsing untrusted sites while logged into the AP admin interface.

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 ACERA device model
    Check the device label, web interface login page, or administrative console for the exact model number (e.g., Acera 1210, 1150i, 1110, 1020, 1010, 950, 850f)
    Affected if The device is any of the ACERA models listed in the affected products
  2. Locate the firmware version
    Access the web administrative interface and navigate to the Status or System Information page to view the installed firmware version, or check the device documentation for CLI commands to retrieve firmware version
    Affected if The firmware version cannot be determined or is at or below the affected thresholds
  3. Compare firmware version against affected ranges
    Match your installed firmware version to the affected thresholds: Acera 1210 <= 02.36, Acera 1150i/1150w <= 01.35, Acera 1110 <= 01.76, Acera 1020/1010 <= 01.86, Acera 950/850f <= 01.60
    Affected if Your firmware version is at or below the threshold for your specific model
  4. Confirm the web management interface is enabled
    Check if the HTTP/HTTPS web administrative interface is accessible on the device by attempting to reach the login page or checking the device network configuration
    Affected if The web interface is enabled and accessible on the network

You are affected if your ACERA device model and firmware version fall within the affected ranges AND the web management interface is enabled, allowing an authenticated session to be hijacked via CSRF.
