This issue affects NTC2218, NTC2250, NTC2299: from 1.0.1.1 through 2.2.6.19. The issue is both present on the PowerPC versions of the modem and the ARM versions.
A stack buffer buffer overflow in the swdownload binary allows attackers to execute arbitrary code. The parse_INFO function uses an unrestricted `sscanf` to read a string of an incoming network packet into a statically sized buffer.
