SIPLUS variants) (All versions), SIMATIC S7-400 H V6 CPU family (incl. SIPLUS variants) (All versions < V6.0.9), SIMATIC S7-400 PN/DP V6 and below CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-410 CPU family (incl. SIPLUS variants) (All versions < V8.2.1), SIPLUS S7-400 CPU 414-3 PN/DP V7 (All versions < V7.0.3), SIPLUS S7-400 CPU 416-3 PN/DP V7 (All versions < V7.0.3), SIPLUS S7-400 CPU 416-3 V7 (All versions), SIPLUS S7-400 CPU 417-4 V7 (All versions). Sending of specially crafted packets to port 102/tcp via Ethernet interface via PROFIBUS or Multi Point Interfaces (MPI) could cause a denial of service condition on affected devices. Flashing with a firmware image may be required to recover the CPU.
Successful exploitation requires an attacker to have network access to port 102/tcp via Ethernet interface or to be able to send messages via PROFIBUS or Multi Point Interfaces (MPI) to the device. No user interaction is required. If no access protection is configured, no privileges are required to exploit the security vulnerability. The vulnerability could allow causing a denial of service condition of the core functionality of the CPU, compromising the availability of the system. plural SIMATIC The product contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. SiemensSIMATICS7-400 is a programmable logic controller for manufacturing and process automation in Siemens, Germany. An input validation vulnerability exists in the Siemens SIMATIC S7-400. An attacker could exploit the vulnerability by sending a specially crafted packet to the TCP port 102. Siemens SIMATIC S7-400 CPU is prone to multiple denial-of-service vulnerabilities. Remote attackers may exploit these issues to cause denial-of-service conditions, denying service to legitimate users. A vulnerability has been identified in SIMATIC S7-400 (incl. At the time of advisory publication no public exploitation of this security vulnerability was known. The vulnerability stems from the failure of the network system or product to properly validate the input data

Sending of specially crafted packets to port 102/tcp via Ethernet interface\r\nvia PROFIBUS or Multi Point Interfaces (MPI) could cause a denial of service\r\ncondition on affected devices. Flashing with a firmware image may be required\r\nto recover the CPU. \r\n\r\nSuccessful exploitation requires an attacker to have network access to port\r\n102/tcp via Ethernet interface or to be able to send messages via PROFIBUS or\r\nMulti Point Interfaces (MPI) to the device. No user interaction is required. \r\nIf no access protection is configured, no privileges are required to exploit\r\nthe security vulnerability. The vulnerability could allow causing a\r\ndenial of service condition of the core functionality of the CPU,\r\ncompromising the availability of the system. plural SIMATIC The product contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. SiemensSIMATICS7-400 is a programmable logic controller for manufacturing and process automation in Siemens, Germany. An input validation vulnerability exists in the Siemens SIMATIC S7-400. An attacker could exploit the vulnerability by sending a specially crafted packet to the TCP port 102. Siemens SIMATIC S7-400 CPU is prone to multiple denial-of-service vulnerabilities. \nRemote attackers may exploit these issues to cause denial-of-service conditions, denying service to legitimate users. A vulnerability has been identified in SIMATIC S7-400 (incl. At the time of advisory publication no public exploitation of this security vulnerability was known. The vulnerability stems from the failure of the network system or product to properly validate the input data",
