CVE-2015-10123Network attack vector

Remote code execution via unchecked WBM buffer copy

Published Mar 13, 2024 · Updated Oct 23, 2024

A buffer overflow in WAGO controller WBM through FW13 allows remote attackers to execute code after an authenticated user views crafted data. The web management interface copies attacker-supplied packet data into a fixed-size buffer without checking its length. Exploitation requires an authenticated user to open the affected WBM page, after which injected code gains full device access.
