CVE-2024-5433Network attack vector

Unauthenticated file access via crafted match expressions

Published May 28, 2024 · Updated Aug 1, 2024

Path traversal in Campbell Scientific CSI Web Server 1.6 and RTMC 5.0 allows remote attackers to read files outside the web root. The command that returns the most recent file matching an expression resolves a crafted expression without confining the resulting path to the web-server root. Anonymous access is enabled by default, exposing files and directories readable by the service account without prior authentication.
