Vulnerability Data

An improper access control vulnerability exists in WSO2 Enterprise Integrator product due to insufficient permission restrictions on internal SOAP admin services related to system logs and user-store configuration. A low-privileged user can access log data and user-store configuration details that…

are not intended to be exposed at that privilege level. While no credentials or sensitive user information are exposed, this vulnerability may allow unauthorized visibility into internal operational details, which could aid in further exploitation or reconnaissance.

MITRE ATT&CK Enterprise TechniquesAI

T1654 Log Enumeration Discovery
Adversaries may enumerate system and service logs to find useful data.
Why these techniques?

Direct unauthorized access to system logs by low-privileged user via exposed SOAP services enables log enumeration (T1654); user-store config access aids reconnaissance but lacks sensitive data exposure.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization checks on the internal SOAP admin services so that low-privileged users cannot retrieve log data or user-store configuration.

prevent

Requires that only the minimum privileges needed for a user's role are granted, eliminating the excessive permissions that allow access to admin-only log and configuration services.

prevent

Enforces information-flow policies that can block unauthorized disclosure of sensitive operational data (logs, user-store config) from the admin services to lower-privileged callers.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
