CVE-2023-43697Network attack vector

Site disruption via mutable file paths

Published Oct 9, 2023 · Updated Dec 9, 2024

Modification of assumed-immutable data in RDT400 on SICK APU0200 before 4.0.0.6 allows remote attackers to disrupt its site. RDT400 accepts HTTP requests that change file-path data assumed to remain immutable, leaving the site unable to load required strings. No authentication or user interaction is required; exploitation alters path data and interrupts site rendering without reported confidentiality impact.
