Unit 42 disclosed an unauthenticated stack‑based buffer overflow in the Siemens ROX II web service (CVE‑2024‑XXXX) affecting firmware versions 2.3.0 through 2.5.1. The flaw resides in a fixed‑size HTTP‑header parser (~1 KB) that lacks length checks, allowing remote attackers to overwrite the return address with >2 KB of header data and execute root‑privileged shellcode on the underlying Linux‑based OT controller. Large language models can generate a functional Python exploit in under 15 minutes, collapsing traditional reverse‑engineering timelines and exposing >12 000 deployed controllers to immediate compromise.
