Title
Privilege Escalation via System REST APIs in Multiple WSO2 Products Permits Admin Account Takeover
Summary
Tokens issued to a low-privileged user are not sufficiently restricted, allowing them to be used to access product-level Admin REST APIs.
Exploitation of this vulnerability allows a low-privileged user to invoke the Admin REST APIs of WSO2 products, potentially leading to full administrative account takeover. This requires the attacker to already possess a low-privileged user account and be able to obtain a valid token for it.
Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
