CVE-2016-5765 — Microfocus Host Access Management And Security Server security vulnerability

Medium CVSS 6.5

Administrative Server in Micro Focus Host Access Management and Security Server (MSS) and Reflection for the Web (RWeb) and Reflection Security Gateway (RSG) and Reflection ZFE (ZFE) allows remote unauthenticated attackers to read arbitrary files via a specially crafted URL that allows limited directory traversal. Applies to MSS 12.3 before 12.3.326 and MSS 12.2 before 12.2.342 and RSG 12.1 before 12.1.362 and RWeb 12.3 before 12.3.312 and RWeb 12.2 before 12.2.342 and RWeb 12.1 before 12.1.362 and ZFE 2.0.1 before 2.0.1.18 and ZFE 2.0.0 before 2.0.0.52 and ZFE 1.4.0 before 1.4.0.14.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
