CVE-2020-23715Public exploitNetwork attack vector

Unauthenticated file disclosure via unchecked download path

Published Jun 28, 2021 · Updated Aug 4, 2024

Path traversal in Webport CMS 1.19.10.17121 allows remote attackers to read arbitrary server files through the file/download endpoint. The endpoint uses the file parameter as a filesystem path without restricting parent-directory traversal sequences, as demonstrated with ../../ payloads. NVD assesses the request as unauthenticated and requiring no user interaction, and the demonstrated consequence is file disclosure only.
