CVE-2024-4879 Scanner

ServiceNow is a cloud-based platform designed to help organizations manage digital workflows for enterprise operations. It is widely used by IT departments for IT service management (ITSM), IT operations management (ITOM), and IT business management (ITBM). The platform integrates with various business tools to streamline processes and improve productivity. ServiceNow is utilized by both large enterprises and small to medium-sized businesses across various industries. Its flexibility allows customization to meet specific organizational needs.

The Server Side Template Injection (SSTI) vulnerability in ServiceNow allows unauthenticated users to inject malicious code into the platform. This vulnerability can lead to remote code execution, giving attackers the ability to execute arbitrary code on the server. The issue is caused by improper input validation in the UI macros of the platform. Patching this vulnerability is crucial to prevent unauthorized access and potential data breaches.

The SSTI vulnerability in ServiceNow is present in the UI macros of the platform. Attackers can exploit this by sending specially crafted requests to the ServiceNow instance. The vulnerable endpoint is the login page, where the malicious code is injected via the jvar_page_title parameter. When the server processes this input, the injected code is executed within the context of the Now Platform. ServiceNow has released updates to address this issue, and users are advised to apply these patches promptly.

Exploitation of this SSTI vulnerability can have severe consequences. Attackers could gain remote code execution capabilities, allowing them to execute arbitrary commands on the server. This can lead to data breaches, unauthorized access to sensitive information, and potentially full control over the affected ServiceNow instance. Such an attack can disrupt business operations and compromise the integrity and confidentiality of organizational data.
