An input validation vulnerability exists in the HTTP-WRITEOEM handler due to insufficient validation of user-supplied data before it is processed by internal flash-write handling logic. Successful exploitation may cause httpd process or device to crash, resulting in loss of access to the web interface and a denial-of-service condition.
