Four format string injection vulnerabilities exist in the XCMD testWifiAP functionality of Abode Systems, Inc. iota All-In-One Security Kit 6.9X and 6.9Z. Specially-crafted configuration values can lead to memory corruption, information disclosure and denial of service. An attacker can modify a configuration value and then execute an XCMD to trigger these vulnerabilities.This vulnerability arises from format string injection via the ssid and ssid_hex configuration parameters, as used within the testWifiAP XCMD handler
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
| Name | Vendor | Start Version | End Version |

| Iota_all-in-one_security_kit_firmware | Goabode | 6.9x (including) | 6.9x (including) |
| Iota_all-in-one_security_kit_firmware | Goabode | 6.9z (including) | 6.9z (including) |
When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
