Descriptions

There is a JavaScript injection vulnerability in certain Huawei smartphones. A module does not verify some inputs sufficiently. Attackers can exploit this vulnerability by sending a malicious application request to launch JavaScript injection. This may compromise normal service. Affected product versions include HUAWEI P30 versions earlier than 10.1.0.165(C01E165R2P11), 11.0.0.118(C635E2R1P3), 11.0.0.120(C00E120R2P5), 11.0.0.138(C10E4R5P3), 11.0.0.138(C185E4R7P3), 11.0.0.138(C432E8R2P3), 11.0.0.138(C461E4R3P3), 11.0.0.138(C605E4R1P3), and 11.0.0.138(C636E4R3P3).

Se presenta una vulnerabilidad de inyección de JavaScript en determinados teléfonos inteligentes de Huawei. Un módulo no verifica suficientemente algunas entradas. Los atacantes pueden explotar esta vulnerabilidad mediante el envío de una petición de aplicación maliciosa para iniciar la inyección de JavaScript. Esto puede comprometer el servicio normal. Las versiones de producto afectadas incluyen versiones de HUAWEI P30 anteriores a 10.1.0.165(C01E165R2P11), 11.0.0.118(C635E2R1P3), 11.0.0.120(C00E120R2P5), 11.0.0.138(C10E4R5P3), 11.0.0.138(C185E4R2P3), 11.0.0.138(C185E4R2P3) , 11.0.0.138(C461E4R3P3), 11.0.0.138(C605E4R1P3) y 11.0.0.138(C636E4R3P3)
