Description

Several SCALANCE X switches contain vulnerabilities in the web server of the affected devices. An unauthenticated attacker could reboot, cause denial-of-service conditions and potentially impact the system by other means through heap and buffer overflow vulnerabilities. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where updates are not, or not yet available.
