Siemens Simatic S7-400 Cpu 412-2 Pn V7 vulnerabilities

CVE-2025-40820 [HIGH] CWE-940 CVE-2025-40820: Affected products do not properly enforce TCP sequence number validation in specific scenarios but a 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 addres

CVE-2022-25622 [HIGH] CWE-400 CVE-2022-25622: The PROFINET (PNIO) stack, when integrated with the Interniche IP stack, improperly handles internal 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 services on affected devices by sending specially crafted TCP segments.

CVE-2019-10936 [HIGH] CWE-400 CVE-2019-10936: Affected devices improperly handle large amounts of specially crafted UDP packets. This could all 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.

CVE-2019-10923 [HIGH] CWE-400 CVE-2019-10923: An attacker with network access to an affected product may cause a denial of service condition by br 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.
