Local device compromise via exposed AT command
Published Jun 4, 2020 · Updated Aug 4, 2024
Improper access control in LG MTK mobile devices running Android 7.2, 8.0, 8.1, 9, and 10 allows local users to invoke a dangerous AT command. An exposed, unused AT command remains callable on the MTK chipset interface, but LG has not disclosed the command, its handler, or the operations it performs. Local low-privileged access is required, and the concrete device effects available through the command are not publicly described.
