Authenticated code execution via unchecked settings buffers
Published Nov 8, 2023 · Updated Jan 16, 2025
Stack-based buffer overflow in Zavio IP Cameras M2.1.6.05 allows remote authenticated users to execute code via network requests. While updating certain settings, the firmware writes request data into an allocated stack buffer without sufficiently validating its size. Low-privileged access to the network interface is required, and successful exploitation executes code with the affected process's privileges.
