An unencrypted 'pause encryption request' message causes a denial of service in the in the RS9116W/SiWx917. See vulnerability B-E10 in the related paper below.
A malformed Bluetooth connection request message can cause the RS9116W/SiWx917 to leak potentially sensitive information. See vulnerability B-E4 in the related paper below.
Passkey entry Bluetooth LE legacy pairing can be bypassed in the RS9116W and SiWx917 by manipulating the temporary key value. See vulnerability B-E3 in the related paper below.
An unencrypted 'pause encryption request' message causes a denial of service in the BT122 module. See vulnerability B-E10 in the related paper below.
A malformed Bluetooth connection request message can cause the BT122 to leak potentially sensitive information. See vulnerability B-E4 in the related paper below.
The BT122 module stops advertising after receiving a plaintext 'pause enceryption response' message resulting in a denial of service. See vulnerability B-E2 in the related paper below.
SMP security request (from peripheral) does not include the maximum encryption key size supported. Using a key with less than the maximum keysize makes brute-forcing the key easier. See V6 in BLERP paper linked below.
Re-pairing with a legitimate device can use a lower security level than previous making brute-forcing the LTK easier. See V4 in the BLERP paper linked below.
Bluetooth re-pairing with an existing device can use a lower security level. RS9116W and SiWx91x impacted. See V3 in the BLERP paper linked below.
Spoofing an already bonded device can force either RS9116W or SiWx917 to re-pair/bond with a rogue device. See V1 in BLERP paper below
SYMCRYPTO is the SiXG301's host side hardware engine accessed by PSA crypto library that accelerates symmetric cryptographic operations (AES encryption/decryption and hashing). DPA Countermeasures on SYMCRYPTO can be weakened (reduced entropy) by forcing ce…
An attacker is able to downgrade the security of a Bluetooth LE connection by deleting an existing bond, spoofing the bonded device and creating a new bond.
* Countermeasures for DPA within SYMCRYPTO engine on SixG301xxx devices are not sufficiently random and will eventually repeat. * KSU keys using SYMCRYPTO will be impacted by this vulnerability.
Vulnerable endpoints accept user-controlled input through a URL in JSON format which enables command execution. The commands allowed to execute can open executables. However, the commands cannot pass parameters or arguments. To successfully execute this atta…
An integer underflow vulnerability in Silicon Labs Secure NCP host implementation allows a buffer overread via a specially crafted packet.
An integer underflow vulnerability is present in Silicon Lab’s implementation of PSA Crypto and SE Manager EC-JPAKE APIs during ZKP parsing. Triggering the underflow can lead to a hard fault, causing a temporary denial of service.
A reachable infinite loop via an integer wraparound is present in Silicon Labs' Matter SDK which allows an attacker to trigger a denial of service. A hard reset is required to recover the device.
The Simplicity Device Manager Tool has a Reflected XSS (Cross-site-scripting) vulnerability in several API endpoints. The attacker needs to be on the same network to execute this attack. These APIs can affect confidentiality, integrity, and availability of th…
DPA countermeasures in Silicon Labs' Series 2 devices are not reseeded under certain conditions. This may allow an attacker to eventually extract secret keys through a DPA attack.
A truncated 802.15.4 packet can lead to an assert, resulting in a denial of service.
After receiving a malformed 802.15.4 MAC Data Request the Zigbee Coordinator sends a ‘network leave’ request to Zigbee router resulting in the Zigbee Router getting stuck in a non-rejoinable state. If a suitable parent is not available, the end devices wi…
An integer underflow vulnerability in the Silicon Labs Z-Wave Protocol Controller can lead to out of bounds memory reads.
When a WF200/WGM160P device is configured to operate as an Access Point, it may be vulnerable to a denial of service triggered by a malformed packet. The device may recover automatically or require a hard reset.
The web interface of the Silicon Labs Simplicity Device Manager is exposed publicly and can be used to extract the NTLMv2 hash which an attacker could use to crack the user's domain password.
In a Bluetooth device, using RS9116-WiseConnect SDK experiences a Denial of Service, if it receives malformed L2CAP packets, only hard reset will bring the device to normal operation
