Hard-coded System User Credentials

Critical
julianladisch published GHSA-vf78-3q9f-92g3 Jul 24, 2023

Package

maven org.folio:mod-data-export-spring (Maven)

Affected versions

>=2.0.0, <2.0.2
<1.5.4

Patched versions

>=2.0.2
>=1.5.4, <1.6.0

Description

Impact

The module creates a system user that is used to perform internal module-to-module operations. Credentials for this user are hard-coded in the source code. This makes it trivial to authenticate as this user, resulting in unauthorized access to potentially dangerous APIs, allowing to view and modify configuration including single-sign-on configuration, to read, add and modify user data, and to read and transfer fees/fines in a patron's account.

Patches

Upgrade mod-data-export-spring to >=2.0.2, or a 1.5.x version >=1.5.4.

Workarounds

No known workarounds.

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.
