Patching system image unconditionally перевод - How to Fix Status 7 Error While Flashing Lineage OS ROM
They affect the latest versions 4. Moreover, the OnePlus X ROM can be installed over OnePlus One and vice versa, leading to Denial-of-Service. In addition, the vulnerabilities can also be exploited by physical attackers allowing for easy exploitation of some of the vulnerabilities we previously disclosed. We responsibly reported the issues to OnePlus Security on January 26 , but unfortunately OnePlus did not meet the day disclosure deadline. We also offered OnePlus a day deadline extension on April 9 — to date, the vulnerabilities are still unpatched. Before we dive into the vulnerabilities themselves, we will briefly describe some fundamental properties of Android OTA updates. An OTA update package OTA from now forward is a digitally-signed zip file. The certificate is placed under the zip file comment section. For instance, here is the certificate information of the above OTA. Code ripped from AOSP that dumps this information from OTAs can be found at our GitHub repo:. Then a script, updater-script provided in the OTA which is in charge of the update process, is interpreted by update-binary also provided in the OTA. Another vector for pushing OTAs is sideloading them via the recovery mode UI, which is also possible on devices with a locked bootloader — hence the digital signature prevents both remote and physical attackers from providing malicious OTAs. There are 3 potential vulnerabilities with the OTA verification process described above:. An unauthorized OS downgrade is extremely problematic as it enables exploitation of now-patched vulnerabilities. Consider our previous OnePlus findings, CVE , CVE and CVE There are 3 different goals that attackers can achieve by downgrading the OS, and exploiting old vulnerabilities:. The third goal is different, in the sense that it implies a stricter threat model. The security of downgrades i. We can clearly see that it prevents installation on devices with a newer image, by comparing the value of the ro. In addition, it also prohibits installation on non-Nexus6P angler devices, by comparing the ro. Another way for preventing OTA downgrades is to change the OTA keys for every release. In addition, please note that, at least for MSM-based devices, executing downgraded code but not the partition flashing! Furthermore, using this approach requires a new bootloader to be bundled with every OTA, which is inconvenient. Such crossover can be prevented by having the vendor generate per-product unique OTA key pair. Google does that for all products but not for different models, see next. Therefore, there must be another protection layer — updater-script. Being able to install an OTA of a different ROM means that the adversary could potentially increase the attack surface additional software. Moreover, different ROMs may have different security patch levels. For example, the latest OxygenOS ROM for OnePlus 3T has the Security Patch Level while the latest non-beta HydrogenOS ROM for OnePlus 3T has the Security Patch Level. Many vulnerabilities have been patched since then. Preventing such upgrades could be done, again, by the updater-script — simply check some system property that identifies the installed ROM. We can clearly see that all OnePlus OTAs of different ROMs and products are signed by the same key. Therefore, the aforementioned vulnerabilities could only be prevented by their updater-script. VERSION OU field of the relevant images is set to 0, we have a critical Downgrade vulnerability - CVE Therefore, HydrogenOS can be installed over OxygenOS and vice versa - Same Product ROM Crossover Vulnerability - CVE Therefore we can deduce that OnePlus One OTAs can be installed over OnePlus X and vice versa - Different Product ROM Crossover - CVE By exploiting this vulnerability, installing the OnePlus One OxygenOS OTA over OnePlus X, our device had got into a boot loop it rebooted once the platform was up , which was only remedied by a factory reset. Interestingly, Sagi Kedmi and also independently the community , have discovered that OnePlus pushes the signed-OTA over HTTP, thus it enables a trivial MiTM attack. We have filed CVE for this, as there is absolutely no reason not to use TLS, unnecessarily increasing the attack surface, as we can see next. For example, on a OnePlus 3T device running OxygenOS 4. This JSON response causes the updater app to display the following UI: Consider the following mitmproxy script:. In addition to the MiTM attack vector, a physical attacker may also exploit this vulnerability, by rebooting into recovery and sideloading the OTA. Full Disk Encryption FDE with user credentials. The following shows how we, by exploiting CVE , downgrade OnePlus 3T running OxygenOS 4. Now, the attacker reboots the device to recovery mode, and pushes the 4. Next, the attacker exploits CVE in order to replace the boot partition, even though the bootloader is locked:. Finally, the attacker gains a root shell and inserts a malicious LKM. Notice that we are at OxygenOS 4. Sun RSA public key, bits modulus: Thu May 07 Mon Sep 22 A8 49 AE Failed to update system image. Partition flashing is not allowed finished.
