CVE-2013-4267Public exploitNetwork attack vector

Authenticated command execution via unescaped shell arguments

Published Feb 11, 2020 · Updated Aug 6, 2024

OS command injection in Pydio before 5.0.1 allows remote authenticated users to execute arbitrary commands through crafted plugin parameters. PowerFSController, fsAccessWrapper, and SvnManager concatenate archive names, file names, or revisions into shell commands without escaping them. An account is required; exposure also depends on Power FS or SVN being enabled, or the nondefault Real Size Probing option being enabled.
