There is a path traversal vulnerability in some Huawei products. The vulnerability is due to that the software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly validate the pathname. Successful exploit could allow the attacker to access a location that is outside of the restricted directory by a crafted filename. Affected product versions include:HUAWEI Mate 20 9.0.0.195(C01E195R2P1), 9.1.0.139(C00E133R3P1);HUAWEI Mate 20 Pro 9.0.0.187(C432E10R1P16), 9.0.0.188(C185E10R2P1), 9.0.0.245(C10E10R2P1), 9.0.0.266(C432E10R1P16), 9.0.0.267(C636E10R2P1), 9.0.0.268(C635E12R1P16), 9.0.0.278(C185E10R2P1); Hima-L29C 9.0.0.105(C10E9R1P16), 9.0.0.105(C185E9R1P16), 9.0.0.105(C636E9R1P16); Laya-AL00EP 9.1.0.139(C786E133R3P1); OxfordS-AN00A 10.1.0.223(C00E210R5P1); Tony-AL00B 9.1.0.257(C00E222R2P1).

There is a buffer overflow vulnerability in several Huawei products. The system does not sufficiently validate certain configuration parameter which is passed from user that would cause buffer overflow. The attacker should trick the user into installing and running a malicious application with a high privilege, successful exploit may cause code execution. Affected product include Huawei HONOR 20 PRO, Mate 20, Mate 20 Pro, Mate 20 X, P30, P30 Pro, Hima-L29C, Laya-AL00EP, Princeton-AL10B, Tony-AL00B, Yale-L61A, Yale-TL00B and YaleP-AL10B.

The system does not properly sign certain encrypted file, the attacker should gain the key used to encrypt the file, successful exploit could cause certain file be forged

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 2 out of 2 vulnerabilities. Different than CVE-2020-5302.

HUAWEI Mate 20 Pro smartphones versions earlier than 10.0.0.175(C00E69R3P8) have an improper authentication vulnerability. The software does not sufficiently validate the name of apk file in a special condition which could allow an attacker to forge a crafted application as a normal one. Successful exploit could allow the attacker to bypass digital balance function.

Mate 20 Pro smartphones with versions earlier than 9.1.0.135(C00E133R3P1) have an improper authorization vulnerability. The software does not properly restrict certain operation of certain privilege, the attacker could trick the user into installing a malicious application before the user turns on student mode function. Successful exploit could allow the attacker to bypass the limit of student mode function.
