CVE-2024-47903Network attack vector

Unauthenticated file write via privileged web server

Published Oct 23, 2024 · Updated Oct 23, 2024

Arbitrary file write in Siemens InterMesh 7177 before 8.2.12 and 7707 before 7.2.12 allows remote attackers to alter the DocumentRoot. The embedded web server creates attacker-chosen files in its served directory while operating with privileges beyond those required for the service. No authentication or user interaction is required; the 7707 is exposed only when its nondefault IP interface is enabled, and root code execution requires chaining with other flaws.
