CVE-2022-25347Network attack vector

Arbitrary file write via unrestricted absolute paths

Published Mar 29, 2022 · Updated Apr 16, 2025

Path traversal in Delta Electronics DIAEnergie before 1.8.02.004 allows remote attackers to write arbitrary files via crafted paths. The affected file-handling code accepts an attacker-supplied absolute pathname without restricting the destination to the intended directory. No authentication or user interaction is required, and successful requests can place files anywhere permitted by the service account.
