CVE-2019-9060 — An issue was discovered in CMS Made Simple 2.2.8
High
CVSS 7.5
An issue was discovered in CMS Made Simple 2.2.8. It is possible to achieve unauthenticated path traversal in the CGExtensions module (in the file action.setdefaulttemplate.php) with the m1_filename parameter; and through the action.showmessage.php file, it is possible to read arbitrary file content (by using that path traversal with m1_prefname set to cg_errormsg and m1_resettodefault=1).

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.
