Unauthenticated code execution via custom AT command overflow
Published Jun 4, 2020 · Updated Aug 4, 2024
Buffer overflow in the custom AT command handler on LG mobile devices with Android OS 7.2 through 10 allows remote attackers to execute code. Public records identify the custom handler as the overflow locus but do not disclose the affected function, buffer, or unchecked operation. Network access without privileges or user interaction is sufficient, and successful exploitation runs attacker-controlled code on the device.
