CVE-2026-9359: Command Injection in Edimax EW-7438RPn
A vulnerability was identified in Edimax EW-7438RPn 1.28a. Affected by this vulnerability is the function formHwSet of the file /goform/formHwSet of the component POST Request Handler. The manipulation of the argument Anntena/Mcs/regDomain/nic0Addr/nic1Addr/wlanAddr/wanAddr/wlanSSID/wlanChan/comd/initgain/txcck/txofdm leads to command injection. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
This vulnerability exists in the Edimax EW-7438RPn device firmware version 1.28a, specifically in the formHwSet function handling POST requests. Attackers can manipulate parameters such as Anntena, Mcs, regDomain, nic0Addr, nic1Addr, wlanAddr, wanAddr, wlanSSID, wlanChan, comd, initgain, txcck, and txofdm to inject arbitrary commands. The flaw allows remote attackers to execute commands on the device without authentication or user interaction. The vendor was notified but did not respond or release a fix. No official remediation or patch is currently available.
Potential Impact
Successful exploitation allows remote command injection on the affected device, potentially enabling attackers to execute arbitrary commands with the privileges of the POST request handler. This could lead to device compromise, unauthorized control, or disruption of network operations. The medium CVSS score reflects the network attack vector and low complexity but limited impact scope and privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded or released a fix, users should consider mitigating exposure by restricting network access to the device's management interface, disabling remote management if possible, or replacing the device with a secure alternative. Monitor for updates from Edimax regarding patches or official mitigations.
