CVE-2020-12850 — The following vulnerability applies only to the Pydio Cells Enterprise OVF version 2.0.4

High CVSS 7

The following vulnerability applies only to the Pydio Cells Enterprise OVF version 2.0.4. Prior versions of the Pydio Cells Enterprise OVF (such as version 2.0.3) have a looser policy restriction allowing the “pydio” user to execute any privileged command using sudo. In version 2.0.4 of the appliance, the user pydio is responsible for running all the services and binaries that are contained in the Pydio Cells web application package, such as mysqld, cells, among others. This user has privileges restricted to run those services and nothing more.

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
