Affected versions

< 2.16.0

Patched versions

2.16.0

Description

Impact

The Fides webserver is vulnerable to a type of Denial of Service (DoS) attack. Attackers can exploit this vulnerability to upload zip files containing malicious SVG bombs (similar to a billion laughs attack), causing resource exhaustion in Admin UI browser tabs and creating a persistent denial of service of the 'new connector' page (datastore-connection/new).

This vulnerability affects Fides versions 2.11.0 through 2.15.1. Exploitation is limited to users with elevated privileges with the CONNECTOR_TEMPLATE_REGISTER scope, which includes root users and users with the owner role.

Patches

The vulnerability has been patched in Fides version 2.16.0. Users are advised to upgrade to this version or later to secure their systems against this threat.

Workarounds

There is no known workaround to remediate this vulnerability without upgrading.

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.
