Description

Impact

Instructors can upload csv files containing learner information to create cohorts in the instructor dashboard. These files are uploaded using the django default storage. With certain storage backends, uploads may become publicly available. This patch ensures that cohorts data uploaded to AWS S3 buckets is written with a private ACL. Beyond patching, deployers should also ensure that existing cohorts uploads have a private ACL, or that other precautions are taken to avoid public access.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
