Description

Impact

Harbor fails to validate the user permissions when updating tag immutability policies - API call:

PUT /projects/{project_name_or_id}/immutabletagrules/{immutable_rule_id}

By sending a request to update a tag immutability policy with an id that belongs to a
project that the currently authenticated user doesn’t have access to, the attacker could
modify tag immutability policies configured in other projects.

Patches

This and similar issues are fixed in Harbor v2.5.2 and later. Please upgrade as soon as possible.

Workarounds

There are no workarounds available.

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.
