CVE-2024-46424Public exploitNetwork attack vector

Service interruption via unbounded File parameter copy

Published Sep 16, 2024 · Updated Sep 17, 2024

A buffer overflow in UploadCustomModule in TOTOLINK T8 4.1.5cu.861_B20230220 allows remote attackers to interrupt service via File. UploadCustomModule reads the POST File value into v8 and calls strcpy(v15, v8) without checking the destination size, overflowing v15. The published proof of concept supplies a SESSION_ID cookie, but the public record does not explain whether a valid session is required.
