  • SSA-313313SSA-313313: Denial of Service Vulnerability in the FTP Server of Nucleus RTOS2022-10-11csaf · siemens_psirtDE

    The FTP server of the networking component (Nucleus NET) in Nucleus Real-Time Operating System (RTOS) does not properly release memory resources that were reserved for incomplete connection attempts by FTP clients. This could allow a remote attacker to generate a denial of service condition on devices that incorporate a vulnerable version of the FTP server. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens is preparing further updates and recommends specific countermeasures for products where updates are not, or not yet available.
