Cross-site scripting (XSS) vulnerability in the Create Employee feature in Hybris Management Console (HMC) in SAP Hybris before 5.0.4.11, 5.1.0.x before 5.1.0.11, 5.1.1.x before 5.1.1.12, 5.2.0.x and 5.3.0.x before 5.3.0.10, 5.4.x before 5.4.0.9, 5.5.0.x before 5.5.0.9, 5.5.1.x before 5.5.1.10, 5.6.x before 5.6.0.8, and 5.7.x before 5.7.0.9 allows remote authenticated users to inject arbitrary web script or HTML via the Name field.
SAP Hybris Management Console (HMC) is vulnerable to a Cross-Site Scripting (XSS) attack, allowing attackers to inject malicious code into the application. This vulnerability, exploitable through the 'Name' field in the 'Create Employee' feature, could lead to account compromise, data theft, or complete control of a user's session. Successful exploitation requires an authenticated user account within the Hybris environment.
Step 1: Authentication: The attacker must first authenticate to the Hybris Management Console (HMC) with valid credentials. This is a prerequisite for exploiting the vulnerability.
Step 2: Payload Injection: The attacker navigates to the 'Create Employee' feature within the HMC. They input a malicious payload (e.g., <script>alert('XSS')</script>) into the 'Name' field.
Step 3: Payload Storage (Indirect): The malicious payload is saved within the application's data store, associated with the newly created employee. This storage is not the direct cause of the XSS, but it allows the payload to be rendered later.
Step 4: Payload Rendering: When a legitimate user views the employee details (e.g., through a list or profile view), the application retrieves the employee's name (including the malicious payload) from the data store.
Step 5: Execution: The application renders the employee's name in the HTML output without proper sanitization or encoding. The browser then interprets the injected JavaScript payload, executing the attacker's code within the context of the user's session. This allows the attacker to perform actions on behalf of the user, such as stealing their session cookies or redirecting them to a malicious website.
The vulnerability stems from insufficient input validation and output encoding within the 'Create Employee' feature of the Hybris Management Console. Specifically, the application fails to properly sanitize user-supplied input entered into the 'Name' field before rendering it in the application's HTML output. This allows an attacker to inject malicious JavaScript or HTML code. The lack of proper input validation allows the attacker to bypass security checks, and the absence of output encoding (e.g., HTML entity encoding) prevents the browser from interpreting the injected code as data, instead of executable code. The root cause is a missing or inadequate implementation of security best practices related to handling user-provided data within the web application's framework. The specific function responsible for rendering the employee name likely directly incorporates the user-provided input without proper sanitization or encoding. This is a classic example of a reflected XSS vulnerability.
