CVE-2026-9424: OS Command Injection in Edimax EW-7438RPn
A weakness has been identified in Edimax EW-7438RPn 1.31. The affected element is the function formWlanMP of the file /goform/formWlanMP of the component Content-Type Handler. Executing a manipulation of the argument ateFunc/ateGain/ateTxCount/ateChan/ateRate/ateMacID/e2pTxPower1/e2pTxPower2/e2pTxPower3/e2pTxPower4/e2pTxPower5/e2pTxPower6/e2pTxPower7/e2pTx2Power1/e2pTx2Power2/e2pTx2Power3/e2pTx2Power4/e2pTx2Power5/e2pTx2Power6/e2pTx2Power7/ateTxFreqOffset/ateMode/ateBW/ateAntenna/e2pTxFreqOffset/e2pTxPwDeltaB/e2pTxPwDeltaG/e2pTxPwDeltaMix/e2pTxPwDeltaN/readE2P can lead to os command injection. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
This vulnerability affects Edimax EW-7438RPn firmware version 1.31, specifically the formWlanMP function in the /goform/formWlanMP file within the Content-Type Handler component. By manipulating one or more of the specified parameters (such as ateFunc, ateGain, ateTxCount, etc.), an attacker can perform OS command injection remotely. This could allow execution of arbitrary commands on the affected device. The vulnerability has been publicly disclosed, and exploit code is available. The vendor has not issued any response or patch, and no official remediation guidance is available.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary OS commands on the affected device, potentially compromising device integrity and confidentiality. Given the medium CVSS score (5.3), the impact is significant but not critical. There is no evidence of exploitation in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no patch is available, users should consider disabling affected functionality if possible or isolating the device from untrusted networks until a fix is released.
