CVE-2025-5350 Scanner

WSO2 is a major provider of middleware solutions, widely utilized by enterprises to manage APIs, applications, and integration tasks. Their products are mainly used by developers and IT operations teams seeking robust solutions for scaling and managing software applications. Most notably, WSO2's open-source model provides flexibility and customization to IT infrastructures, making it a popular choice across diverse industries. WSO2's offerings serve as crucial integration layers in large-scale environments like cloud deployments, giving organizations agility in their technology operations. Its role is instrumental in API management, providing secure and effective application interaction. As the digital transformation expands, WSO2 products continue to be integral in connecting various technology ecosystems efficiently.

The vulnerability found in WSO2 components is a Server-Side Request Forgery (SSRF). This occurs when an attacker is able to make requests from the server to internal or external services. Often resulting from improper validation of input URLs, SSRF can be a severe issue leading to unauthorized data access or manipulation. SSRF poses a notable threat as it can facilitate access to restricted server resources and services. Attackers may use SSRF to scan internal network services, execute admin browser exploits, and stealthily retrieve sensitive data. Exploitation of SSRF can directly compromise the confidentiality and integrity of critical information within an enterprise network.

Technically, the SSRF vulnerability in question leverages improper URL validation and direct reflection of content. This is specifically notable within the deprecated "Try-It" feature of WSO2 which is only accessible to administrative users. It allows malicious users to trick willing administrators into unsolicited actions by directly querying internal services through manipulated URLs. The vulnerability's key weakness is its interaction with rogue data and administrative permissions, thus exploiting sensitive internal data. The template is designed to test interactions and redirects through carefully crafted GET requests, using encoded payloads to stress test these vulnerable elements. Particular attention is paid to how the system processes and validates incoming URL requests.

If exploited by malicious actors, this SSRF vulnerability can have far-reaching consequences. Attackers can execute arbitrary JavaScript in administrative browsers, creating opportunities for session hijacking or similar exploits. There is also a significant risk of malicious internal network requests, which may lead to data exfiltration or unauthorized enumeration of internal services. This could ultimately result in UI manipulation or unauthorized access to sensitive data, potentially damaging reputations and causing financial losses. The exploitation further poses a threat to the confidentiality, integrity, and availability of internal systems.
