EPSS · scored 2026-10-22

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.

  • SSA-780073SSA-780073: Denial of Service Vulnerability in PROFINET Devices via DCE-RPC Packets2020-02-11csaf · siemens_psirtDE

    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 new versions for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where fixes are not, or not yet available. Additionally, Siemens recommends other vendors of PROFINET devices to check if their products have incorporated a vulnerable version of the Siemens PNIO stack as part of the Siemens Development/Evaluation Kits.
