最近收了个古早的安卓平板,由于配置还行,尚感觉堪用。但由于系统自带垃圾软件太多,故想办法直接ROOT了它
基于CVE-2017-8890编写ARM32移植及构造ROP Chain

设备信息

SoC:QCOM MSM8974
RAM:2GB
Flash:64GB
Android版本:4.4.4
Linux版本:3.4.0
软件版本:V13R29B(可能兼容:V11R27F/V12R28B)

由于该设备仅用于测试用途,故未安装权限管理器,在此使用给Settings添加语言作为ROOT成功之范例

注意

由于富士通使用私有的LSM进行保护内核功能,请在使用exp提权之后,直接insmod LSM_Disabler.ko,如Shell无任何返回(于Dmesg会返回<!><LSM_Disabler>SUCCESS),再执行rmmod lsm_disabler即可完整解除保护

      1.Use adb to push those two files into /data/local/tmp.
      2.Give permission in rwxrwxrwx to those two files.
      3.Try to run ./exp in shell. If it success, you will get # in shell. If failed,hold VOL+/- and Power to Hard Restart and try again.
      4.Insmod LSM_Disabler and Rmmod it.
      5.Enjoy it!
