TITLE

HUAWEI Mate 20 Pro Authentication vulnerabilities in smartphones

Trust: 0.8

sources: JVNDB: JVNDB-2020-001324

DESCRIPTION

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. An attacker can exploit this vulnerability by disguising a specially crafted software package as a normal software package to bypass the relevant functions of a healthy mobile phone
