Critical CVSS 9.1

Absolute path traversal vulnerability in Quick.CMS, version 6.7, the exploitation of which could allow remote users to bypass the intended restrictions and download any file if it has the appropriate permissions outside of documentroot configured on the server via the aDirFiles%5B0%5D parameter in the admin.php page. This vulnerability allows an attacker to delete files stored on the server due to a lack of proper verification of user-supplied input.

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.
