Unauthorized access to data in @sap-cloud-sdk/core

Moderate severity GitHub Reviewed Published Nov 5, 2021 in SAP/cloud-sdk-js • Updated Feb 1, 2023

Package

npm @sap-cloud-sdk/core (npm)

Affected versions

< 1.52.0

Patched versions

1.52.0

Description

Impact

This affects applications on SAP Business Technology Platform that use the SAP Cloud SDK and enabled caching of destinations.
In some cases, when user information was missing, destinations were cached without user information, allowing other users to retrieve the same destination with its permissions.
By default, destination caching is disabled. If it is enabled the maximum lifetime is 5 minutes which limits the attack vector.

Patches

The problem was fixed by #1769 and #1770. The security for caching has been increased. The changes are released in version 1.52.0.

Workarounds

Disable destination caching (it is disabled by default).

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.
