GHSA-j63j-7r7r-5v4j: WSO2 products vulnerable to privilege escalation due to business logic flaw in SOAP admin services
A privilege escalation vulnerability exists in multiple WSO2 products due to a business logic flaw in SOAP admin services. A malicious actor can create a new user with elevated permissions only when all of the following conditions are met:
- SOAP admin services are accessible to the attacker.
- The deployment includes an internally used attribute that is not part of the default WSO2 product configuration.
- At least one custom role exists with non-default permissions.
- The attacker has knowledge of the custom role and the internal attribute used in the deployment.
Exploiting this vulnerability allows malicious actors to assign higher privileges to self-registered users, bypassing intended access control mechanisms.
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.
