AI Analysis

Impact

The vulnerability is a buffer overflow in the formWlSiteSurvey component of the Edimax BR‑6208AC firmware version 1.32, triggered by an overflow of the ifname argument. This flaw can be triggered remotely through the device’s web interface and allows an attacker to overwrite memory, leading to arbitrary code execution or denial of service. The weakness falls under CWE‑119 and CWE‑120, indicating a classic out‑of‑bounds write that may compromise the entire device.

Affected Systems

The only affected vendor is Edimax, model BR‑6208AC. Firmware 1.32 is targeted. The product is no longer supported by the maintainer, meaning no official patch or security updates are available. Any device currently running the 1.32 build is vulnerable.

Risk and Exploitability

With a CVSS score of 9.4 the vulnerability is classified as critical. Although a recent EPSS score is not available, the published exploit indicates that attackers can achieve remote code execution over the network. The device is not listed in CISA’s KEV catalog, but the absence of a fix should not be interpreted as low risk. Attackers could exploit the web interface from any machine that can reach the device, making the risk high for any enterprise or home network that exposes the device to the internet or untrusted LAN segments.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • If the device is still in use, block or segregate its network access so that the web interface cannot be reached from untrusted sources; apply firewall rules to restrict access to a trusted local network only.
  • Disable the device’s web management interface altogether if the firmware supports it, or remove the /goform/formWlSiteSurvey endpoint by deleting the file from the filesystem when possible.
  • Replace the Edimax BR‑6208AC with a newer, supported device that receives security updates, or discontinue the use of the device in critical environments.
