我们决定将EMFI探针修复到绕过Secure Boot成功的Glitch的位置。这样便可以将故障参数的搜索空间降低一个维度。 0x06 漏洞利用 Espressif IoT开发框架(ESP-IDF)中包含许多便捷的工具,包括编译软件(idf.py)、刻录eFuses(espefuse.py)、生成密钥(espsecure.py)、对内存进行编程(esptool.py)。我们在寻找漏洞利用方法的过...
I can tell that the eFuse of ABS_DONE_0 is checked with 1. So my partitions table and app is checked. And the flash encryption also worked. I noticed the change of FLASH_CRYPT_CNT. But the secure boot check fail. I'm doubtful about the verification. ...
如果想避免因服务器应用程序的安全版本号低于运行的应用程序,造成不必要的下载和擦除,必须从镜像的第一个包中获取new_app_info.secure_version,和 eFuse 的安全版本号比较。如果esp_efuse_check_secure_version(new_app_info.secure_version)函数为真,则下载继续,反之则中断。
