CVE-2019-9015 — A Path Traversal vulnerability was discovered in MOPCMS through 2018-11-30, leading to deletion of unexpected critical files

Critical CVSS 9.1

A Path Traversal vulnerability was discovered in MOPCMS through 2018-11-30, leading to deletion of unexpected critical files. The exploitation point is in the "column management" function. The path added to the column is not verified. When a column is deleted by an attacker, the corresponding directory is deleted, as demonstrated by ./ to delete the entire web site.

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.
