WSO2 Integrator Mediator State Leakage via Improper Isolation
CVE-2024-4598 Published on September 23, 2025
Information Disclosure in Multiple WSO2 Products Due to Improper Handling in Enrich Mediator
An information disclosure vulnerability exists in multiple WSO2 products due to improper implementation of the enrich mediator. Authenticated users may be able to view unintended business data from other mediation contexts because the internal state is not properly isolated or cleared between executions.
This vulnerability does not impact user credentials or access tokens but may lead to leakage of sensitive business information handled during message flows.
Vulnerability Analysis
CVE-2024-4598 is exploitable with network access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Type
Improper Restriction of Security Token Assignment
The System-On-A-Chip (SoC) implements a Security Token mechanism to differentiate what actions are allowed or disallowed when a transaction originates from an entity. However, the Security Tokens are improperly protected. Systems-On-A-Chip (Integrated circuits and hardware engines) implement Security Tokens to differentiate and identify which actions originated from which agent. These actions may be one of the directives: 'read', 'write', 'program', 'reset', 'fetch', 'compute', etc. Security Tokens are assigned to every agent in the System that is capable of generating an action or receiving an action from another agent. Multiple Security Tokens may be assigned to an agent and may be unique based on the agent's trust level or allowed privileges. Since the Security Tokens are integral for the maintanence of security in an SoC, they need to be protected properly. A common weakness afflicting Security Tokens is improperly restricting the assignment to trusted components. Consequently, an improperly protected Security Token may be able to be programmed by a malicious agent (i.e., the Security Token is mutable) to spoof the action as if it originated from a trusted agent.
