CWE
- CWE-476 - NULL Pointer Dereference
Summary
arduino-TuyaOpen before version 1.2.1 contains a null pointer dereference vulnerability in the WiFiUDP component. An attacker on the same local area network can send a large volume of malicious UDP packets to cause memory exhaustion on the device, triggering a null pointer dereference and resulting in a denial-of-service condition.

CWE
- CWE-122 - Heap-based Buffer Overflow
Summary
arduino-TuyaOpen before version 1.2.1 contains a heap-based buffer overflow vulnerability in the DnsServer component. An attacker on the same local area network who controls the LAN DNS server can send malicious DNS responses to overflow the heap buffer, potentially allowing execution of arbitrary code on affected embedded devices.

CWE
- CWE-404 - Denial of Service
Summary
A vulnerability was determined in Tuya App and SDK 24.07.11 on Android. Affected by this vulnerability is an unknown functionality of the component JSON Data Point Handler. This manipulation of the argument cruise_time causes denial of service. Remote exploitation of the attack is possible. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been publicly disclosed and may be utilized. There is ongoing doubt regarding the real existence of this vulnerability. The vendor disagrees with the conclusion of the finding: "The described vulnerability fails to prove its feasibility or exploitability by attackers. The issue essentially does not constitute a security vulnerability, aligning more closely with abnormal product functionality." These considerations are properly reflected within the CVSS vector.

CWE
- CWE-404 - Denial of Service
Summary
** DISPUTED ** A vulnerability classified as problematic has been found in Tuya SDK up to 5.0.x. Affected is an unknown function of the component MQTT Packet Handler. The manipulation leads to denial of service. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. Upgrading to version 5.1.0 is able to address this issue. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-260604. NOTE: The vendor explains that a malicious actor would have to crack TLS first or use a legitimate login to initiate the attack.
