CVSS v3.1

Official Description

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.

Technical Analysis

CVE-2020-12850 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.0.
