HUAWEI Mate 20 smart phones with Versions earlier than 10.1.0.163(C00E160R3P8) have a denial of service (DoS) vulnerability. The attacker can enter a large amount of text on the phone. Due to insufficient verification of the parameter, successful exploitation can impact the service.

HUAWEI Mate 20 smartphones with 9.0.0.205(C00E205R2P1) have a logic error vulnerability. In a special scenario, the system does not properly process. As a result, attackers can perform a series of operations to successfully establish P2P connections that are rejected by the peer end. As a result, the availability of the device is affected.

HUAWEI Mate 20 versions earlier than 10.1.0.160(C00E160R3P8), HUAWEI Mate 20 X versions earlier than 10.1.0.135(C00E135R2P8), HUAWEI Mate 20 RS versions earlier than 10.1.0.160(C786E160R3P8), and Honor Magic2 smartphones versions earlier than 10.1.0.160(C00E160R2P11) have a path traversal vulnerability. The system does not sufficiently validate certain pathname from certain process, successful exploit could allow the attacker write files to a crafted path.

HUAWEI Mate 20 smartphones with versions earlier than 10.0.0.195(SP31C00E74R3P8) have an improper authorization vulnerability. The digital balance function does not sufficiently restrict the using time of certain user, successful exploit could allow the user break the limit of digital balance function after a series of operations with a PC.

HUAWEI Mate 20 smartphones with versions earlier than 10.0.0.185(C00E74R3P8) have an improper authorization vulnerability. The system does not properly restrict certain operation in ADB mode, successful exploit could allow certain user break the limit of digital balance function.

There are two denial of service vulnerabilities on some Huawei smartphones. An attacker may send specially crafted TD-SCDMA messages from a rogue base station to the affected devices. Due to insufficient input validation of two values when parsing the messages, successful exploit may cause device abnormal. This is 1 out of 2 vulnerabilities. Different than CVE-2020-5303. Affected products are: ALP-AL00B: earlier than 9.1.0.333(C00E333R2P1T8) ALP-L09: earlier than 9.1.0.300(C432E4R1P9T8) ALP-L29: earlier than 9.1.0.315(C636E5R1P13T8) BLA-L29C: earlier than 9.1.0.321(C636E4R1P14T8), earlier than 9.1.0.330(C432E6R1P12T8), earlier than 9.1.0.302(C635E4R1P13T8) Berkeley-AL20: earlier than 9.1.0.333(C00E333R2P1T8) Berkeley-L09: earlier than 9.1.0.350(C10E3R1P14T8), earlier than 9.1.0.351(C432E5R1P13T8), earlier than 9.1.0.350(C636E4R1P13T8) Charlotte-L09C: earlier than 9.1.0.311(C185E4R1P11T8), earlier than 9.1.0.345(C432E8R1P11T8) Charlotte-L29C: earlier than 9.1.0.325(C185E4R1P11T8), earl…

HUAWEI Mate 20 smartphones with versions earlier than 10.0.0.188(C00E74R3P8) have an improper authorization vulnerability. The software does not properly restrict certain user's modification of certain configuration file, successful exploit could allow the attacker to bypass app lock after a series of operation in ADB mode.

There is a logic error vulnerability in several smartphones. The software does not properly restrict certain operation when the Digital Balance function is on.
