CVE-2026-9348: Stack-based Buffer Overflow in Edimax EW-7438RPn
A vulnerability was found in Edimax EW-7438RPn up to 1.31. Affected by this vulnerability is an unknown functionality of the file /goform/mp of the component webs. The manipulation of the argument webs results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been made public and could be used. 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 devices running firmware versions up to 1.31. It involves a stack-based buffer overflow triggered by manipulating the webs argument in the /goform/mp component. The vulnerability allows remote attackers to execute code or cause denial of service due to the overflow. The CVSS 4.0 base score is 8.7, indicating high severity with network attack vector, low complexity, no user interaction, and high impact on confidentiality, integrity, and availability. The vendor has not issued any patch or advisory, and no cloud service is involved.
Potential Impact
Successful exploitation of this vulnerability can lead to remote code execution or denial of service on affected Edimax EW-7438RPn devices. The attacker requires only network access and low privileges, with no user interaction needed. The vulnerability impacts confidentiality, integrity, and availability of the device. No known exploits are currently observed in the wild, but a public exploit exists.
Mitigation Recommendations
No official patch or remediation is currently available from the vendor, and the vendor has not responded to disclosure attempts. Users should monitor vendor channels for updates. Until a fix is released, consider isolating affected devices from untrusted networks to reduce exposure. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
