CVE-2019-13941Network attack vector

Unauthenticated project-file disclosure via predictable paths

Published Feb 11, 2020 · Updated Aug 5, 2024

Information disclosure in Siemens OZW672 and OZW772 Web Servers before 10.00 allows remote attackers to download exported project files. The servers store legitimately exported project files under predictable path names and serve them when a specific URL is requested. Network access is sufficient and no authentication or user interaction is required; exploitation exposes project-file contents without altering data or service.
