VMware vCloud Director Cross-Site Scripting Scanner

VMware vCloud Director is a cloud service platform used by enterprise organizations to manage virtual data centers and cloud resources. It enables delivery and management of virtual infrastructure and applications with efficiency. IT administrators utilize it to provision and manage cloud environments across private, public, and hybrid infrastructure setups. The platform provides users with advanced networking capabilities, including automated management of complex resources. It is widely deployed in various sectors for optimizing cloud service delivery and ensuring scalable performance. With its comprehensive management tools, customers are able to innovate and implement robust cloud strategies.

Cross-Site Scripting (XSS) is a security vulnerability typically found within web applications. It enables attackers to inject client-side scripts into web pages viewed by other users, potentially compromising user data and session information. In the context of VMware vCloud Director, XSS could result in unauthorized actions being performed in the context of the targeted user's session. This vulnerability arises when scripts are embedded improperly in dynamic content that is rendered to users of the application. Detection of XSS vulnerabilities is crucial as they can lead to further infrastructure compromise and unauthorized data exposure. Addressing XSS vulnerabilities is vital for maintaining the confidentiality, integrity, and availability of cloud services.

Technical details of the detected XSS vulnerability in VMware vCloud Director reveal that user inputs are not properly sanitized. The vulnerable endpoint is within the login parameter, which facilitates the injection of malicious scripts. The specific parameter susceptible to injection includes crafted payloads that are not filtered before being stored or reflected back to the user. This improper handling allows the malicious script to execute whenever an unsuspecting user or administrator accesses the affected endpoint. The vulnerability manifests as a non-escaped insertion point in HTML content, breaching the security controls expected by application users. Ensuring that all user input is rigorously sanitized and properly encoded is essential to mitigate this risk.

Exploitation of the Cross-Site Scripting vulnerability could lead to various adverse effects like theft of cookies, session hijacking, and execution of arbitrary actions with the privileges of the compromised user. Attackers could perform successful phishing attacks by displaying fraudulent content, resulting in the exposure of sensitive information such as authentication credentials. It may also facilitate further attacks such as Denial of Service (DoS) or unauthorized transactions if exploited correctly within critical application workflows. Overall, this vulnerability represents a significant threat by potentially undermining the security posture of an enterprise cloud environment.
