Technical details
The web server fails to properly limit or manage system resources when processing a high volume of concurrent HTTP requests. An unauthenticated remote attacker can exploit this denial-of-service vulnerability via network access without authentication or user interaction. By sending a flood of concurrent HTTP requests, an attacker can exhaust system resources, causing the device to crash and reboot. The vulnerability affects all versions prior to V2.70; Siemens has released patches and recommends immediate update to V2.70 or later.
