Technical details
A stack-based buffer overflow (CWE-121) exists in the /boafrm/formAjaxSet JSON API handler when processing the ApCliWEPKey field in the setWiFiRepeaterConfig branch. The vulnerable code uses unbounded strcpy() to copy user-supplied JSON input into a 68-byte stack buffer without length validation, allowing payloads over 67 bytes to overflow. Authentication is required; exploitation in emulation confirmed device crash at 3000-byte payload, with potential for controlled code execution on the root-privileged boa web server process.
