CVE-2023-31716Network attack vector

Unauthenticated log disclosure via crafted file parameter

Published Sep 21, 2023 · Updated Sep 24, 2024

Local file inclusion in Frangoteam FUXA 1.1.12 and earlier allows remote attackers to read server log data via a crafted file parameter. The public record identifies file=fuxa.log as the trigger but does not disclose the affected endpoint, code locus, or filename-validation failure. No authentication or user interaction is required, and the documented consequence is limited to confidentiality loss rather than file modification or service interruption.
