CVE-2019-3394 — There was a local file disclosure vulnerability in Confluence Server and Confluence Data Center via page exporting

High CVSS 8.8

There was a local file disclosure vulnerability in Confluence Server and Confluence Data Center via page exporting. An attacker with permission to editing a page is able to exploit this issue to read arbitrary file on the server under <install-directory>/confluence/WEB-INF directory, which may contain configuration files used for integrating with other services, which could potentially leak credentials or other sensitive information such as LDAP credentials. The LDAP credential will be potentially leaked only if the Confluence server is configured to use LDAP as user repository. All versions of Confluence Server from 6.1.0 before 6.6.16 (the fixed version for 6.6.x), from 6.7.0 before 6.13.7 (the fixed version for 6.13.x), and from 6.14.0 before 6.15.8 (the fixed version for 6.15.x) are affected by this vulnerability.

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.
