An unauthenticated remote command execution vulnerability exists in AjaXplorer (now known as Pydio Cells) versions prior to 2.6. The flaw resides in the checkInstall.php script within the access.ssh plugin, which fails to properly sanitize user-supplied input to the destServer GET parameter. By injecting shell metacharacters, remote attackers can execute arbitrary system commands on the server with the privileges of the web server process.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
