var-202204-0684
Vulnerability from variot

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. simatic cfu diq firmware, SIMATIC CFU PA firmware, SIMATIC S7-300 CPU Multiple Siemens products such as firmware contain a resource exhaustion vulnerability.Service operation interruption (DoS) It may be in a state. The SIMATIC S7-400 CPU family is designed for process control in industrial environments. The SIMATIC S7-300 CPU family is designed for discrete and continuous control in industrial environments. The SIMATIC S7-1500 CPU family is designed for discrete and continuous control in industrial environments. The SIMATIC Compact Field Unit (SIMATIC CFU) is an intelligent field distributor. The SIMATIC ET 200 interface module is used to connect field devices (IO devices) to the controller via PROFINET. SIMATIC TDC is a multiprocessor automation system for drive, control and technical tasks. SIMATIC WinAC RTX is the SIMATIC software controller for PC-based automation solutions. SIPLUSextreme products are designed for reliable operation under extreme conditions. The SIMIT Simulation Platform allows the simulation of plant setups to predict failures at an early planning stage.

A denial of service vulnerability exists in Siemens PROFINET Stack Integrated on Interniche Stack. 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)
