Multiple integer overflows in the HMI application in DATAC RealFlex RealWin 2.1 (Build 6.1.10.10) and earlier allow remote attackers to execute arbitrary code via crafted (1) On_FC_MISC_FCS_MSGBROADCAST and (2) On_FC_MISC_FCS_MSGSEND packets, which trigger a heap-based buffer overflow.

Security readout for executives and security teams

This CVE describes a remote code execution flaw in DATAC RealFlex RealWin HMI 2.1 Build 6.1.10.10 and earlier. A crafted network packet can corrupt memory in the HMI application. For an industrial control environment, compromise of an HMI can affect visibility, operator actions, and operational continuity. Exposure is most likely in legacy industrial sites still running DATAC RealFlex RealWin 2.1 Build 6.1.10.10 or earlier, especially where HMI services are reachable from untrusted networks or flat OT segments. Prioritize remediation for any reachable legacy RealWin HMI. The business risk is highest where the HMI supports live operations or sits on a flat OT network. If no supported fix is available, containment and vendor-directed upgrade planning should be treated as operational risk reduction. Mitigation focus: Confirm vendor guidance for fixed versions or supported upgrade paths.; Remove RealWin HMI access from the internet and untrusted networks.; Segment affected HMI systems from corporate and external access..
