Certain WSO2 products allow unrestricted file upload with resultant remote code execution. The attacker must use a /fileupload endpoint with a Content-Disposition directory traversal sequence to reach a directory under the web root, such as a ../../../../repository/deployment/server/webapps directory. This affects WSO2 API Manager 2.2.0 up to 4.0.0, WSO2 Identity Server 5.2.0 up to 5.11.0, WSO2 Identity Server Analytics 5.4.0, 5.4.1, 5.5.0 and 5.6.0, WSO2 Identity Server as Key Manager 5.3.0 up to 5.11.0, WSO2 Enterprise Integrator 6.2.0 up to 6.6.0, WSO2 Open Banking AM 1.4.0 up to 2.0.0 and WSO2 Open Banking KM 1.4.0, up to 2.0.0.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.8, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 8 products from wso2, from wso2, from wso2 and 5 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2022, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For wso2's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
