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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
