CVE-2020-11531 — Zohocorp Manageengine Adaudit Plus security vulnerability

High CVSS 8.8

The DataEngine Xnode Server application in Zoho ManageEngine DataSecurity Plus prior to 6.0.1 does not validate the database schema name when handling a DR-SCHEMA-SYNC request. This allows an authenticated attacker to execute code in the context of the product by writing a JSP file to the webroot directory via directory traversal.

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.
