CVE-2026-29522 — ZwickRoell Test Data Management security vulnerability
High
CVSS 8.7
ZwickRoell Test Data Management versions prior to 3.0.8 contain a local file inclusion (LFI) vulnerability in the /server/node_upgrade_srv.js endpoint. An unauthenticated attacker can supply directory traversal sequences via the firmware parameter to access arbitrary files on the server, leading to information disclosure of sensitive system files.

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.
