Privilege escalation via exported firewall component
Published Jul 13, 2022 · Updated Aug 3, 2024
Improper access control in Android SoC telephony allows local users to gain elevated privileges through a third-party app. The com.sprd.firewall manifest leaves its component exported as true, allowing third-party apps to cross the intended application boundary. Exploitation requires code execution as a third-party app on an affected Unisoc-based device; public records omit the callable interface and resulting privilege level.
