CVE-2025-40944 1 Siemens 15 Simatic Et 200al Im 157-1 Pn, Simatic Et 200mp Im 155-5 Pn Hf, Simatic Et 200sp Im 155-6 Mf Hf and 12 more 2026-01-14 7.5 High
A vulnerability has been identified in SIMATIC ET 200AL IM 157-1 PN (6ES7157-1AB00-0AB0) (All versions), SIMATIC ET 200MP IM 155-5 PN HF (6ES7155-5AA00-0AC0) (All versions >= V4.2.0), SIMATIC ET 200SP IM 155-6 MF HF (6ES7155-6MU00-0CN0) (All versions), SIMATIC ET 200SP IM 155-6 PN HA (incl. SIPLUS variants) (All versions < V1.3), SIMATIC ET 200SP IM 155-6 PN R1 (6ES7155-6AU00-0HM0) (All versions < V6.0.1), SIMATIC ET 200SP IM 155-6 PN/2 HF (6ES7155-6AU01-0CN0) (All versions >= V4.2.0), SIMATIC ET 200SP IM 155-6 PN/3 HF (6ES7155-6AU30-0CN0) (All versions < V4.2.2), SIMATIC PN/MF Coupler (6ES7158-3MU10-0XA0) (All versions), SIMATIC PN/PN Coupler (6ES7158-3AD10-0XA0) (All versions < V6.0.0), SIPLUS ET 200MP IM 155-5 PN HF (6AG1155-5AA00-2AC0) (All versions >= V4.2.0), SIPLUS ET 200MP IM 155-5 PN HF (6AG1155-5AA00-7AC0) (All versions >= V4.2.0), SIPLUS ET 200MP IM 155-5 PN HF T1 RAIL (6AG2155-5AA00-1AC0) (All versions >= V4.2.0), SIPLUS ET 200SP IM 155-6 PN HF (6AG1155-6AU01-2CN0) (All versions >= V4.2.0), SIPLUS ET 200SP IM 155-6 PN HF (6AG1155-6AU01-7CN0) (All versions >= V4.2.0), SIPLUS ET 200SP IM 155-6 PN HF T1 RAIL (6AG2155-6AU01-1CN0) (All versions >= V4.2.0), SIPLUS ET 200SP IM 155-6 PN HF TX RAIL (6AG2155-6AU01-4CN0) (All versions >= V4.2.0), SIPLUS NET PN/PN Coupler (6AG2158-3AD10-4XA0) (All versions < V6.0.0). Affected devices do not properly handle S7 protocol session disconnect requests. When receiving a valid S7 protocol Disconnect Request (COTP DR TPDU) on TCP port 102, the devices enter an improper session state. This could allow an attacker to cause the device to become unresponsive, leading to a denial-of-service condition that requires a power cycle to restore normal operation.
CVE-2025-40820 1 Siemens 16 Sidoor Atd430w, Sidoor Ate530s Coated, Simatic and 13 more 2025-12-10 7.5 High
Affected products do not properly enforce TCP sequence number validation in specific scenarios but accept values within a broad range. This could allow an unauthenticated remote attacker e.g. to interfere with connection setup, potentially leading to a denial of service. The attack succeeds only if an attacker can inject IP packets with spoofed addresses at precisely timed moments, and it affects only TCP-based services.
CVE-2017-2681 1 Siemens 155 Dk Standard Ethernet Controller, Dk Standard Ethernet Controller Firmware, Ek-ertec 200 Pn Io and 152 more 2025-04-20 6.5 Medium
Specially crafted PROFINET DCP packets sent on a local Ethernet segment (Layer 2) to an affected product could cause a denial of service condition of that product. Human interaction is required to recover the system. PROFIBUS interfaces are not affected.
CVE-2017-2680 1 Siemens 183 S110 Pn, Dk Standard Ethernet Controller, Dk Standard Ethernet Controller Firmware and 180 more 2025-04-20 6.5 Medium
Specially crafted PROFINET DCP broadcast packets could cause a denial of service condition of affected products on a local Ethernet segment (Layer 2). Human interaction is required to recover the systems. PROFIBUS interfaces are not affected.
CVE-2017-12741 1 Siemens 76 Dk Standard Ethernet Controller, Dk Standard Ethernet Controller Firmware, Ek-ertec 200p and 73 more 2025-04-20 7.5 High
Specially crafted packets sent to port 161/udp could cause a denial of service condition. The affected devices must be restarted manually.
CVE-2019-10923 1 Siemens 78 Cp1604, Cp1604 Firmware, Cp1616 and 75 more 2025-02-11 7.5 High
An attacker with network access to an affected product may cause a denial of service condition by breaking the real-time synchronization (IRT) of the affected installation.
CVE-2019-10936 1 Siemens 130 Dk Standard Ethernet Controller, Dk Standard Ethernet Controller Firmware, Ek-ertec 200 and 127 more 2024-11-21 7.5 High
Affected devices improperly handle large amounts of specially crafted UDP packets. This could allow an unauthenticated remote attacker to trigger a denial of service condition.
