Recommendation: Plan a near-term fix — a public PoC already exists.

Stack-based buffer overflow in the CmpWebServer component in 3S CoDeSys 3.4 SP4 Patch 2 and earlier, as used on the ABB AC500 PLC and possibly other products, allows remote attackers to execute arbitrary code via a long URI to TCP port 8080.
