Today we share a fun little Huawei bug that adds a twist to our previous forays into Neural Networking-based exploitation of Android devices. In previous posts, we have shown that the Neural Networking features of modern Android devices can lead to serious - if quite traditional - vulnerabilities. This time, we present a vulnerability in which Machine Learning is not the culprit - but the tool we use to actually exploit a seemingly minor permission misconfiguration issue! Introduction This time last year while auditing vendor-specific filesystem node access rights, we’ve spotted an SELinux permission misconfiguration issue that, at first, looked somewhat innocuous: all untrusted applications could access a sysfs-based log file of condensed haptic event statistics.
