CVE-2023-38295

Arbitrary system file access via missing permission

Published Apr 22, 2024 · Updated Aug 2, 2024

Incorrect permissions in TCL 10L RKQ1.210107.001 and TCL 30Z SP1A.210812.016 firmware allow local users to read and write system files. DataService trusts com.tct.smart.switchphone.permission.SWITCH_DATA when a third-party app defines it as a normal permission, leaving the service unprotected at runtime. Exploitation requires installation and execution of a local app but no further user interaction, and file operations execute in the system service's context.
