CVE-2020-27630 1 Silabs 1 Uc\/tcp-ip 2024-11-21 9.8 Critical
In Silicon Labs uC/TCP-IP 3.6.0, TCP ISNs are improperly random.
CVE-2020-15532 1 Silabs 1 Bluetooth Low Energy Software Development Kit 2024-11-21 6.5 Medium
Silicon Labs Bluetooth Low Energy SDK before 2.13.3 has a buffer overflow via packet data. This is an over-the-air denial of service vulnerability in Bluetooth LE in EFR32 SoCs and associated modules running Bluetooth SDK, supporting Central or Observer roles.
CVE-2020-15531 1 Silabs 1 Bluetooth Low Energy Software Development Kit 2024-11-21 8.8 High
Silicon Labs Bluetooth Low Energy SDK before 2.13.3 has a buffer overflow via packet data. This is an over-the-air remote code execution vulnerability in Bluetooth LE in EFR32 SoCs and associated modules running Bluetooth SDK, supporting Central or Observer roles.
CVE-2020-13582 1 Silabs 1 Micrium Uc-http 2024-11-21 7.5 High
A denial-of-service vulnerability exists in the HTTP Server functionality of Micrium uC-HTTP 3.01.00. A specially crafted HTTP request can lead to denial of service. An attacker can send an HTTP request to trigger this vulnerability.
CVE-2020-10137 1 Silabs 2 700 Series Firmware, Uzb-7 2024-11-21 6.5 Medium
Z-Wave devices based on Silicon Labs 700 series chipsets using S2 do not adequately authenticate or encrypt FIND_NODE_IN_RANGE frames, allowing a remote, unauthenticated attacker to inject a FIND_NODE_IN_RANGE frame with an invalid random payload, denying service by blocking the processing of upcoming events.
CVE-2018-25029 1 Silabs 10 Zgm130s037hgn, Zgm130s037hgn Firmware, Zgm2305a27hgn and 7 more 2024-11-21 8.1 High
The Z-Wave specification requires that S2 security can be downgraded to S0 or other less secure protocols, allowing an attacker within radio range during pairing to downgrade and then exploit a different vulnerability (CVE-2013-20003) to intercept and spoof traffic.
CVE-2018-19983 1 Silabs 4 Z-wave S0, Z-wave S0 Firmware, Z-wave S2 and 1 more 2024-11-21 N/A
An issue was discovered on Sigma Design Z-Wave S0 through S2 devices. An attacker first prepares a Z-Wave frame-transmission program (e.g., Z-Wave PC Controller, OpenZWave, CC1110, etc.). Next, the attacker conducts a DoS attack against the Z-Wave S0 Security version product by continuously sending divided "Nonce Get (0x98 0x81)" frames. The reason for dividing the "Nonce Get" frame is that, in security version S0, when a node receives a "Nonce Get" frame, the node produces a random new nonce and sends it to the Src node of the received "Nonce Get" frame. After the nonce value is generated and transmitted, the node transitions to wait mode. At this time, when "Nonce Get" is received again, the node discards the previous nonce value and generates a random nonce again. Therefore, because the frame is encrypted with previous nonce value, the received normal frame cannot be decrypted.
CVE-2013-20003 1 Silabs 10 Zgm130s037hgn, Zgm130s037hgn Firmware, Zgm2305a27hgn and 7 more 2024-11-21 8.3 High
Z-Wave devices from Sierra Designs (circa 2013) and Silicon Labs (using S0 security) may use a known, shared network key of all zeros, allowing an attacker within radio range to spoof Z-Wave traffic.
CVE-2024-23938 1 Silabs 1 Gecko Os 2024-10-03 8.8 High
Silicon Labs Gecko OS Debug Interface Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the debug interface. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-23184
