Detection & IOCs extracted from sources · hover to see the quote

• · The exploit sends each crafted packet twice over the same TCP connection; detection rules should account for duplicate packet transmission rather than expecting a single send. ↗
• · Function codes 8, 9, A, and V are noted as additional valid function codes beyond the 1–7 range tested in the PoC; detection coverage should not be limited to only function bytes 1–7. ↗
• · The vulnerability affects Progea Movicon 11.2 builds prior to Build 1084 only; patched systems running Build 1084 or later are not affected. ↗
