CVE-2024-48406Network attack vector

Code execution via truncated exponentiation result

Published Nov 29, 2024 · Updated Dec 4, 2024

Integer overflow in the power function in SunBK201 umicat 0.3.2 and earlier allows remote attackers to execute arbitrary code. The recursive function stores its uct_int_t result in an int, truncating large values before subsequent res-by-res multiplications. Network access requires no authentication or user interaction, but upstream material does not identify which request data controls x or n.
