Summary
An authorization flaw in the Kiteworks Core administrative import function allowed a delegated administrator to import a privileged integration credential without the required entitlement check. Under certain permission configurations, this could let a narrowly privileged administrator gain full system administrator access without approval from an existing system administrator.
Affected context
The issue occurs in deployments where:
- Delegated administrators can access the administrative import function
- The import process handles privileged integration credentials
- Authorization checks do not confirm that the requesting administrator is entitled to create or import the credential
The risk depends on the permissions assigned to delegated administrators and the protections surrounding administrative credential imports.
Exploit preconditions
- Attack surface: Administrative import functionality in Kiteworks Core
- Required access: An authenticated delegated administrator with a narrowly scoped administrative permission
- Trigger point: Importing a privileged integration credential
- Why exploitation is possible: The import workflow fails to enforce an authorization check linking the requested credential privilege to the administrator's entitlement
Why this happens
The underlying bug is an authorization enforcement failure in a privileged administrative workflow. The application verifies that the requester can access the import function but does not adequately verify that the requester is authorized to create or import the specific privileged credential.
This maps to CWE-284: Improper Access Control, where a security-sensitive operation is permitted without enforcing the required authorization policy. The insecure pattern is treating feature-level access as sufficient authorization for the privilege level of the resource being created.
Potential impact
- A delegated administrator could gain full system administrator privileges
- Attackers could modify system-wide security or configuration settings
- Administrative accounts, integrations, or access policies could be compromised
- Sensitive data could be exposed or altered
- System integrity and availability could be affected
General mitigation guidance
Mitigation generally focuses on enforcing authorization at the point where privileged credentials are created or imported.
Common defensive patterns include:
- Applying object- and operation-level authorization checks to every administrative import
- Verifying that the requester is entitled to the exact privilege represented by the credential
- Separating delegated administration from system-level credential management
- Requiring independent approval or dual control for highly privileged credential changes
- Applying least privilege to administrative roles and integration credentials
- Recording and monitoring all privileged imports and authorization decisions
Authorization should be denied by default when the requester's entitlement cannot be established.
How teams detect issues like this
Organizations can assess for this class of issue through:
- Static and architectural review of administrative import workflows
- Code review checks for authorization decisions based only on endpoint or feature access
- Tests that exercise each delegated role against privileged credential operations
- Policy enforcement requiring explicit privilege-to-operation entitlement checks
- Audit-log analysis for privileged credential imports performed by delegated administrators
Automated security testing and code review tools may help identify missing authorization checks, but coverage should include business-logic and role-combination scenarios.
