CVE-2023-24256Public exploit

Persistent root escalation via module path traversal

Published Jul 6, 2023 · Updated Nov 19, 2024

Path traversal in NIO Aspen before 3.3.0 allows local users with shell access to gain persistent root privileges on an EC6. /system/bin/setup_touch.sh accepts a traversal-bearing persist.sys.touchscreen value and passes the resolved .ko path to insmod without confinement. Shell access first reaches the system-app context through debuggable com.nextev.datastatistic; loading the attacker-controlled module then preserves root across reboots.
