Vulnerabilidades

Improper bounds validation in EmberZNet SDK versions 9.0.2 and earlier may result in crashes or dynamic memory leakage.

In EmberZNet v9.0.2 and earlier, malformed global ZCL messages can trigger out-of-bounds reads in framework parsing logic and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed.

In EmberZNet v9.0.2 and earlier, a malformed GetProfileResponse message can trigger out-of-bounds reads while iterating interval entries and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices…

In EmberZNet v9.0.2 and earlier, a malformed Level Control Step command can terminate the process through a divide-by-zero fault. This command must come from a device that has already joined the network. Only devices supporting the Level Control cluster may be impacted.

In EmberZNet v9.0.2 and earlier, a malformed Level Control Move command can terminate the process through a divide-by-zero fault. This command must come from a device that has already joined the network. Only devices supporting the Level Control cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed ClearWeekdaySchedule messages can trigger out-of-bounds writes into Door Lock schedule state. The size and location of this data is limited. These messages must come from a device that has already joined the network. Only devices supporting the Door Lock cluster may be…

In EmberZNet v9.0.2 and earlier, malformed IAS Zone enrollment messages can trigger an out-of-bounds state-table write and terminate the process. The size and location of this write is limited. These messages must come from a device that has already joined the network. Only devices supporting the IAS Zone cluster may…

In EmberZNet v9.0.2 and earlier, malformed or out-of-range Door Lock user identifiers can trigger out-of-bounds table reads and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices supporting the Door…

In EmberZNet v9.0.2 and earlier, malformed GetGroupMembership commands can trigger repeated reads past the end of the message payload and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices…

In EmberZNet v9.0.2 and earlier, malformed OTA requests can drive the OTA server parser into out-of-bounds reads. A limited amount of data from RAM is read back to the requester. The size and location of this data is limited. These requests must come from a device that has already joined the network. Only devices…

In EmberZNet v9.0.2 and earlier, malformed Color Control messages can lead to asserts that terminate the process. These messages must come from a device that has already joined the network. Only devices supporting the Color Control cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed Color Control messages can lead to asserts that terminate the process. These messages must come from a device that has already joined the network. Only devices supporting the Color Control cluster may be impacted.

A Zigbee Radio Co-Processor (RCP), which is using SiLabs EmberZNet Zigbee stack, was unable to send messages to the host system (CPCd) due to heavy Zigbee traffic, resulting in a Denial of Service (DoS) attack, Only hard reset will bring the device to normal operation

High traffic environments may result in NULL Pointer Dereference vulnerability in Silicon Labs's Ember ZNet SDK before v7.4.0, causing a system crash.

Due to an allocation of resources without limits, an uncontrolled resource consumption vulnerability exists in Silicon Labs Ember ZNet SDK prior to v7.4.0.0 (delivered as part of Silicon Labs Gecko SDK v4.4.0) which may enable attackers to trigger a bus fault and crash of the device, requiring a reboot in order to…

Ember ZNet between v7.2.0 and v7.4.0 used software AES-CCM instead of integrated hardware cryptographic accelerators, potentially increasing risk of electromagnetic and differential power analysis sidechannel attacks.

Missing Encryption of Security Keys vulnerability in Silicon Labs Ember ZNet SDK on 32 bit, ARM (SecureVault High modules) allows potential modification or extraction of network credentials stored in flash. This issue affects Silicon Labs Ember ZNet SDK: 7.3.1 and earlier.

TouchLink packets processed after timeout or out of range due to Operation on a Resource after Expiration and Missing Release of Resource after Effective Lifetime may allow a device to be added outside of valid TouchLink range or pairing duration This issue affects Ember ZNet 7.1.x from 7.1.3 through 7.1.5; 7.2.x from…

A malformed packet containing an invalid destination address, causes a stack overflow in the Ember ZNet stack. This causes an assert which leads to a reset, immediately clearing the error.

A malformed packet causes a stack overflow in the Ember ZNet stack. This causes an assert which leads to a reset, immediately clearing the error.

Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Silicon Labs Ember ZNet allows Overflow Buffers.
