CVE-2020-13795Public exploitNetwork attack vector

Authenticated file overwrite via template path traversal

Published Jun 3, 2020 · Updated Aug 4, 2024

Path traversal in Navigate CMS 2.8.7 and earlier allows remote authenticated users to read or overwrite web-server files. The template loader accepts the request's file value without removing ../ or ..\ sequences, allowing template operations to escape the intended directory. Access to authenticated template functionality is required; overwriting an executable PHP file grants code execution as the web-server account.
