A vulnerability has been identified in SIMATIC CP 343-1 (6GK7343-1EX30-0XE0) (All versions), SIMATIC CP 343-1 Lean (6GK7343-1CX10-0XE0) (All versions), SIPLUS NET CP 343-1 (6AG1343-1EX30-7XE0) (All versions), SIPLUS NET CP 343-1 Lean (6AG1343-1CX10-2XE0) (All versions). Affected products incorrectly validate TCP sequence numbers. This could allow an unauthenticated remote attacker to create a denial of service condition by injecting spoofed TCP RST packets. Se ha identificado una vulnerabilidad en: SIMATIC CP 343-1 (6GK7343-1EX30-0XE0) (todas las versiones), SIMATIC CP 343-1 Lean (6GK7343-1CX10-0XE0) (todas las versiones), SIPLUS NET CP 343-1 (6AG1343- 1EX30-7XE0) (todas las versiones), SIPLUS NET CP 343-1 Lean (6AG1343-1CX10-2XE0) (todas las versiones). Los productos afectados validan incorrectamente los números de secuencia TCP. Esto podría permitir que un atacante remoto no autenticado cree una condición de denegación de servicio inyectando paquetes TCP RST falsificados. • https://cert-portal.siemens.com/productcert/html/ssa-516818.html • CWE-940: Improper Verification of Source of a Communication Channel •

Profinet-IO (PNIO) stack versions prior V06.00 do not properly limit internal resource allocation when multiple legitimate diagnostic package requests are sent to the DCE-RPC interface. This could lead to a denial of service condition due to lack of memory for devices that include a vulnerable version of the stack. The security vulnerability could be exploited by an attacker with network access to an affected device. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise the availability of the device. Las versiones de la pila Profinet-IO (PNIO) anteriores a la V06.00 no limitan adecuadamente la asignación de recursos internos cuando se envían múltiples solicitudes legítimas de paquetes de diagnóstico a la interfaz DCE-RPC. Esto podría conducir a una condición de denegación de servicio debido a la falta de memoria para los dispositivos que incluyen una versión vulnerable de la pila. • https://cert-portal.siemens.com/productcert/html/ssa-780073.html https://cert-portal.siemens.com/productcert/pdf/ssa-780073.pdf • CWE-400: Uncontrolled Resource Consumption •

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. This vulnerability affects only SIMATIC HMI Multi Panels and HMI Mobile Panels, and S7-300/S7-400 devices. Los paquetes PROFINET DCP especialmente diseñados que se envían en un segmento Ethernet local (capa 2) a un producto afectado podrían causar una condición de denegación de servicio de ese producto. • http://www.securityfocus.com/bid/98369 http://www.securitytracker.com/id/1038463 https://cert-portal.siemens.com/productcert/html/ssa-293562.html https://cert-portal.siemens.com/productcert/pdf/ssa-293562.pdf https://www.siemens.com/cert/pool/cert/siemens_security_advisory_ssa-293562.pdf • CWE-400: Uncontrolled Resource Consumption •
