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-2019-6568 1 Siemens 100 Cp1604, Cp1604 Firmware, Cp1616 and 97 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
The webserver of the affected devices contains a vulnerability that may lead to a denial of service condition. An attacker may cause a denial of service situation which leads to a restart of the webserver of the affected device. The security vulnerability could be exploited by an attacker with network access to the affected systems. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise availability of the devi ...

CVE-2018-16561 1 Siemens 8 Simatic S7-300, Simatic S7-300 Firmware, Simatic S7-300f and 5 more 2024-11-21 7.8 HIGH 7.5 HIGH
A vulnerability has been identified in SIMATIC S7-300 CPUs (All versions < V3.X.16). The affected CPUs improperly validate S7 communication packets which could cause a Denial-of-Service condition of the CPU. The CPU will remain in DEFECT mode until manual restart. Successful exploitation requires an attacker to be able to send a specially crafted S7 communication packet to a communication interface of the CPU. This includes Ethernet, PROFIBUS, and Multi Point Interfaces (MPI). No user interactio ...
