Improper authorization in HUAWEI Mate 20 digital balance function allows users to bypass usage time limits via a PC.
Vulnerability
The HUAWEI Mate 20 smartphone contains an improper authorization vulnerability in its digital balance function. The function fails to sufficiently restrict the using time for certain users, allowing a bypass of the limit after performing a series of operations with a PC. This affects versions earlier than 10.0.0.195(SP31C00E74R3P8) [1].
Exploitation
An attacker with physical access to both the smartphone and a PC can exploit the vulnerability by connecting the phone to the PC and executing a sequence of operations that manipulate the digital balance function, thereby breaking the intended time restriction [1].
Impact
Successful exploitation enables the attacker to circumvent the digital balance usage time limit, violating the intended restriction. This compromises the integrity of the feature but does not lead to data disclosure or remote code execution [1].
Mitigation
Huawei has released a software update to fix this vulnerability. Users should upgrade to version 10.0.0.195(SP31C00E74R3P8) or later. No workarounds have been provided [1].
