**Name of the Vulnerable Software and Affected Versions** TPLink Smart Bulb Tapo series L530 versions 1.0.0 through 1.2.3 TPLink Smart Bulb Tapo series L510E versions 1.0.0 through 1.0.9 TPLink Smart Bulb Tapo series L630 versions 1.0.0 through 1.0.3 TPLink Smart Bulb Tapo series P100 versions 1.0.0 through 1.4.9 Tapo Application versions 2.8.14 and earlier **Description** An issue in TPLink Smart Bulb Tapo series allows a remote attacker to replay old messages encrypted with a still valid session key, potentially obtaining sensitive information via the session key in the message function. **Recommendations** For TPLink Smart Bulb Tapo series L530 versions 1.0.0 through 1.2.3, update to version 1.2.4 or later. For TPLink Smart Bulb Tapo series L510E versions 1.0.0 through 1.0.9, update to version 1.1.0 or later. For TPLink Smart Bulb Tapo series L630 versions 1.0.0 through 1.0.3, update to version 1.0.4 or later. For TPLink Smart Bulb Tapo series P100 versions 1.0.0 through 1.4.9, update to version 1.5.0 or later. For Tapo Application versions 2.8.14 and earlier, update to a version later than 2.8.14.

**Name of the Vulnerable Software and Affected Versions** TP-Link Tapo L530 versions prior to 1.2.4 TP-Link Tapo L510E versions prior to 1.1.0 TP-Link Tapo L630 versions prior to 1.0.4 TP-Link Tapo P100 versions prior to 1.5.0 Tapo Application versions prior to 2.8.14 **Description** The issue is related to the lack of use of a random initialization vector with the cipher block chaining mode, allowing a remote attacker to obtain sensitive information via the IV component in the AES128-CBC function. This can enable a brute force attack. **Recommendations** For TP-Link Tapo L530 versions prior to 1.2.4, update to version 1.2.4 or later. For TP-Link Tapo L510E versions prior to 1.1.0, update to version 1.1.0 or later. For TP-Link Tapo L630 versions prior to 1.0.4, update to version 1.0.4 or later. For TP-Link Tapo P100 versions prior to 1.5.0, update to version 1.5.0 or later. For Tapo Application versions prior to 2.8.14, update to version 2.8.14 or later. As a temporary workaround, consider restricting access to the AES128-CBC function until a patch is available.

**Nome do software vulnerável e versões afetadas** Dispositivos Amazon Echo Dot, 3ª e 4ª gerações **Descrição** A vulnerabilidade permite a execução arbitrária de comandos de voz nos dispositivos afetados. Isso pode ser feito por um invasor remoto usando uma skill maliciosa ou por um invasor fisicamente próximo emparelhando um dispositivo Bluetooth malicioso, também conhecido como ataque “Alexa versus Alexa (AvA)”. **Recomendações** Para dispositivos Amazon Echo Dot de 3ª geração, atualize o dispositivo para uma versão que inclua uma correção para este problema. Para dispositivos Amazon Echo Dot de 4ª geração, atualize o dispositivo para uma versão que inclua uma correção para este problema. Como solução alternativa temporária, considere desativar habilidades de fontes não confiáveis e restringir o emparelhamento Bluetooth para minimizar o risco de exploração.
