A vulnerability has been identified in SIMATIC PCS neo (Administration Console) (All versions < V3.1 SP1), SINETPLAN (All versions), TIA Portal (V15, V15.1, V16 and V17). The affected system cannot properly process specially crafted packets sent to port 8888/tcp. A remote attacker could exploit this vulnerability to cause a Denial-of-Service condition. The affected devices must be restarted manually.

A vulnerability has been identified in SCALANCE W1788-1 M12 (All versions < V3.0.0), SCALANCE W1788-2 EEC M12 (All versions < V3.0.0), SCALANCE W1788-2 M12 (All versions < V3.0.0), SCALANCE W1788-2IA M12 (All versions < V3.0.0). Affected devices do not properly handle resources of ARP requests. This could allow an attacker to cause a race condition that leads to a crash of the entire device.

A vulnerability has been identified in SIMATIC CFU DIQ (All versions), SIMATIC CFU PA (All versions), SIMATIC S7-1500 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V2.0.0), SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions), SIMATIC S7-400 H V6 CPU family (incl. SIPLUS variants) (All versions < V6.0.10), SIMATIC S7-400 PN/DP V7 CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-410 V10 CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-410 V8 CPU family (incl. SIPLUS variants) (All versions), SIMATIC TDC CP51M1 (All versions), SIMATIC TDC CPU555 (All versions), SIMATIC WinAC RTX (All versions), SIMIT Simulation Platform (All versions). The PROFINET (PNIO) stack, when integrated with the Interniche IP stack, improperly handles internal resources for TCP segments where the minimum TCP-Header length is less than defined. This could allow an attacker to create a denial of service condition for TCP servic...

In the MZ Automation LibIEC61850 in versions prior to 1.5.1 an unauthenticated attacker can craft a goose message, which may result in a denial of service.

**Why is Scope marked as Changed for this vulnerability?** Successful exploitation of this vulnerability would allow a Hyper-V guest to affect the functionality of the Hyper-V host.

References Identification First version of the Microsoft Malware Protection Engine with this vulnerability addressed Version 1.1.19100.5 See Manage Updates Baselines Microsoft Defender Antivirus for more information. **Microsoft Defender is disabled in my environment, why are vulnerability scanners showing that I am vulnerable to this issue?** Vulnerability scanners are looking for specific binaries and version numbers on devices. Microsoft Defender files are still on disk even when disabled. Systems that have disabled Microsoft Defender are not in an exploitable state. **Why is no action required to install this update?** In response to a constantly changing threat landscape, Microsoft frequently updates malware definitions and the Microsoft Malware Protection Engine. In order to be effective in helping protect against new and prevalent threats, antimalware software must be kept up to date with these updates in a timely manner.
