Short explanation
Multiple WSO2 products contain an information disclosure vulnerability where Event Publisher output adapters configured with irrelevant properties log sensitive data into system log files.
If a malicious actor gains access to the 'wso2carbon' log files, sensitive user credentials can be retrieved, potentially leading to unauthorized access.
What should be done?
- Follow vendor security advisories
- Restrict permissions to log files
- Review Event Publisher configurations

Show the technical text from the sources
When an Event Publisher output adapter is configured with properties that are irrelevant to its function, the affected products log these irrelevant properties. This can inadvertently include sensitive user credentials or other confidential information depending on the nature of the misconfigured property. A malicious actor with access to the 'wso2carbon' log files could retrieve sensitive information logged by the system. This may potentially lead to unauthorized access if the logged data contains credentials or other critical secrets.
