Code injection

The UpdateHub module disables DTLS peer checking, which allows for a man in the middle attack. This is mitigated by firmware images requiring valid signatures. However, there is no benefit to using DTLS without the peer checking. See NCC-ZEP-018 This issue affects: zephyrproject-rtos zephyr versi...

Design/Logic Flaw

In updatehubprobe, right after JSON parsing is complete, objects\1 is accessed from the output structure in two different places. If the JSON contained less than two elements, this access would reference unitialized stack memory. This could result in a crash, denial of service, or possibly an...

CVE-2020-10067 Integer Overflow In is_in_region Allows User Thread To Access Kernel Memory

A malicious userspace application can cause a integer overflow and bypass security checks performed by system call handlers. The impact would depend on the underlying system call and can range from denial of service to information leak to memory corruption resulting in code execution within the...

CVE-2020-10067

CVE-2020-10067 affects Zephyr Project RTOS. A malicious userspace application can trigger an integer overflow that bypasses security checks in system call handlers, with impacts ranging from denial of service to information leak and memory corruption potentially enabling kernel code execution. Af...

CVE-2020-10059 UpdateHub Module Explicitly Disables TLS Verification

The UpdateHub module disables DTLS peer checking, which allows for a man in the middle attack. This is mitigated by firmware images requiring valid signatures. However, there is no benefit to using DTLS without the peer checking. See NCC-ZEP-018 This issue affects: zephyrproject-rtos zephyr versi...

CVE-2020-10060 UpdateHub Might Dereference An Uninitialized Pointer

In updatehubprobe, right after JSON parsing is complete, objects\1 is accessed from the output structure in two different places. If the JSON contained less than two elements, this access would reference unitialized stack memory. This could result in a crash, denial of service, or possibly an...

CVE-2020-10060

CVE-2020-10060 affects Zephyr’s UpdateHub module. The vulnerability arises in updatehub_probe: after JSON parsing, the code accesses objects[1], which can reference uninitialized stack memory if the JSON has fewer than two elements. This could crash the process, cause a denial of service, or pote...

CVE-2020-10059

CVE-2020-10059 affects Zephyr Project RTOS (2.1.0 and later) via the UpdateHub module, which disables DTLS peer checking. This enables a man-in-the-middle risk, mitigated by firmware signatures, with no shown exploit details in the documents. The issue sits with the UpdateHub component and is lin...

CVE-2020-10058

CVE-2020-10058 affects Zephyr Project RTOS (Kscan subsystem). The issue arises from insufficient parameter validation in multiple Kscan syscalls, enabling a local user to potentially gain elevated privileges. Publicly documented details from CNVD-2020-35003 confirm Zephyr 2.1.0 and later are affe...

CVE-2020-10058 Multiple Syscalls In kscan Subsystem Performs No Argument Validation

Multiple syscalls in the Kscan subsystem perform insufficient argument validation, allowing code executing in userspace to potentially gain elevated privileges. See NCC-ZEP-006 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions...

CVE-2020-10028

CVE-2020-10028 concerns Zephyr RTOS, specifically the GPIO subsystem, where multiple syscalls perform no argument validation. Root cause: insufficient validation on syscall parameters, enabling possible improper access or misuse. Affected: Zephyr versions 1.14.0 and later, including 2.1.0 and lat...

CVE-2020-10027 ARC Platform Uses Signed Integer Comparison When Validating Syscall Numbers

An attacker who has obtained code execution within a user thread is able to elevate privileges to that of the kernel. See NCC-ZEP-001 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions...

CVE-2020-10024

This CVE concerns Zephyr RTOS: the ARM platform-specific code uses a signed integer comparison when validating syscall numbers. The root cause enables privilege escalation from a user thread to kernel level if code execution is obtained in user space. Affected versions are Zephyr project-rtos Zep...

CVE-2020-10023 Shell Subsystem Contains a Buffer Overflow Vulnerability In shell_spaces_trim

The shell subsystem contains a buffer overflow, whereby an adversary with physical access to the device is able to cause a memory corruption, resulting in denial of service or possibly code execution within the Zephyr kernel. See NCC-NCC-019 This issue affects: zephyrproject-rtos zephyr version...

CVE-2020-10024 ARM Platform Uses Signed Integer Comparison When Validating Syscall Numbers
