A vulnerability in affected devices could allow an attacker to perform a denial-of-service attack if a large amount of specially crafted UDP packets are sent to the device. Siemens has released updates for several affected products, and recommends that customers update to the new version. Siemens is preparing further updates …

When receiving malformed network data, SIMATIC S7-400 V5 PN CPUs may go into defect mode. This would allow attackers to perform a Denial-of-Service attack on the CPUs. Siemens will not publish a fix for this vulnerability as this product version is discontinued since October 2011 [1]. Version V6 is not …

When receiving specially crafted ICMP network packets, SIMATIC S7-400 V6 PN CPU products may go into defect mode. This could allow attackers to perform a Denial-of-Service attack on the CPUs. Siemens has released updates for the affected products.

Products that include the Siemens PROFINET-IO (PNIO) stack in versions prior V06.00 are potentially affected by a denial-of-service vulnerability when multiple legitimate diagnostic package requests are sent to the DCE-RPC interface. Siemens has released updates for several affected products, and recommends that customers update to the new version. Siemens is …

Two vulnerabilities have been identified in the SIMATIC S7-1200 and S7-1500 CPU families. One vulnerability could allow an attacker with network access to affected devices to modify the user program stored on these devices such that the source code differs from the actual running code. The other vulnerability could allow …
