CVE-2023-45880 — GibbonEdu Gibbon through version 25.0.0 allows Directory Traversal via the report template builder

High CVSS 7.2

GibbonEdu Gibbon through version 25.0.0 allows Directory Traversal via the report template builder. An attacker can create a new Asset Component. The templateFileDestination parameter can be set to an arbitrary pathname (and extension). This allows creation of PHP files outside of the uploads directory, directly in the webroot.

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.
