CVE-2026-2038Network attack vector

Unauthenticated access via missing remoting authorization

Published Feb 20, 2026 · Updated Feb 20, 2026

Missing authorization in GFI Archiver 15.10 allows remote attackers to bypass authentication on the MArc.Core remoting service. MArc.Core.Remoting.exe listens on TCP port 8017 and exposes functionality without performing an authorization check. No credentials are required; the bypass enables unauthorized functionality access and can be chained with other flaws for SYSTEM-level code execution.
