CVE-2022-39048 Scanner Detail

ServiceNow is a cloud-based platform that provides software as a service (SaaS) for technical management support. The platform specializes in IT services management (ITSM), IT operations management (ITOM), and IT business management (ITBM), helping organizations automate and streamline their IT services. ServiceNow is widely used in various industries to manage service requests, incidents, problems, and changes. The platform's versatility and extensive integration capabilities make it a central tool for IT departments seeking to optimize their processes and improve service delivery.

The Cross-site Scripting (XSS) vulnerability discovered in ServiceNow's Quebec version occurs within the UI page assessment_redirect. This vulnerability allows attackers to craft URLs that, when clicked by an authenticated user, execute arbitrary script code in the victim's browser. This could lead to various security breaches, including phishing attempts, session hijackings, and unauthorized actions on the system using the victim's credentials.

To exploit this vulnerability, an attacker would need to persuade a user already authenticated in ServiceNow to click on a specially crafted link. This link would trigger the XSS vulnerability in the assessment_redirect page by injecting malicious script into the sysparm_survey_url parameter. The vulnerability demonstrates a lack of proper input sanitization and output encoding of URL parameters, allowing attackers to execute scripts in the context of the user's session.

Successful exploitation could lead to unauthorized actions being performed on the ServiceNow platform under the guise of the victim's session. This includes accessing sensitive information, modifying data, or performing privileged operations without authorization. Additionally, it could serve as a stepping stone for further attacks, both within the ServiceNow environment and against other systems accessible through the victim's browser.
