CVE-2022-24247 — RiteCMS version 3.1.0 and below suffers from an arbitrary file overwrite via path traversal vulnerability in Admin Panel

High CVSS 8.5

RiteCMS version 3.1.0 and below suffers from an arbitrary file overwrite via path traversal vulnerability in Admin Panel. Exploiting the vulnerability allows an authenticated attacker to overwrite any file in the web root (along with any other file on the server that the PHP process user has the proper permissions to write) resulting a remote code execution.

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.
