Buffer Overflow in Edimax BR-6478AC formUSBFolder

IdentifiersCVE-2026-10164CWE-120· Buffer Copy without Checking Size…

CVE-2026-10164 is a remotely exploitable buffer overflow in Edimax BR-6478AC firmware version 1.23. The flaw affects the formUSBFolder function exposed through the /goform/formUSBFolder POST request handler. According to the available information, improper handling of the ShareName and/or SelectName POST parameters allows an attacker to supply crafted input that overflows a buffer during request processing. Public exploit information is available. The vulnerable condition is associated with classic buffer-copy bounds handling issues and has been mapped in the source material to CWE-119/CWE-120.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can crash the affected service or device and may enable arbitrary code execution, depending on memory layout and exploit reliability. The supplied scoring context indicates high confidentiality, integrity, and availability impact. Because the issue is remotely reachable and public exploit information exists, the risk of unauthorized compromise or service disruption is elevated.

Mitigation

If you can’t patch tonight, do this now.

Until a fixed firmware version is available, restrict access to the router management interface and specifically to the /goform/formUSBFolder endpoint to trusted administrative networks only. Disable remote administration from untrusted networks, place the device behind network ACLs or firewall rules, and monitor for suspicious POST requests containing unusually long ShareName or SelectName values. If feasible, isolate or replace affected devices exposed to hostile networks.

Remediation

Patch, then assume compromise.

Upgrade Edimax BR-6478AC to a vendor-fixed firmware release if one becomes available. The vulnerable code handling ShareName and SelectName in formUSBFolder should be corrected to enforce strict bounds checking, reject oversized input, and use safe memory-handling routines. If source-level remediation is performed by the vendor, all copies and concatenations involving these parameters should be audited for length validation before processing.
