Three distinct vulnerabilities, each with a maximum CVSS score of 10.0, allow anyone on the Internet to execute code on your ServiceNow servers without any authentication. An absolute emergency for the thousands of organizations using the platform.

ServiceNow: Three CVEs Score 10.0, Unauthenticated Remote Code Execution - Patch Urgently

What's Happening

Three distinct vulnerabilities have just been disclosed in ServiceNow, the IT service management platform deployed in thousands of organizations worldwide. All three receive the maximum CVSS score of 10.0/10 and enable Remote Code Execution (RCE) without prior authentication—what the security community calls "pre-auth RCE," the most feared scenario.

An attacker from the internet can execute arbitrary code on your ServiceNow servers without possessing any account on the platform. The three flaws affect different components: multiple exploitation vectors coexist.

Why ServiceNow Is a Critical Target

ServiceNow is not a niche tool: it is one of the most widely deployed ITSM platforms globally, present in large enterprises, government agencies, hospitals, and banks. It manages IT tickets, assets, HR workflows, compliance—and often contains sensitive data (credentials, HR information, system configurations) while being well-connected to the internal network.

An RCE on ServiceNow potentially means: access to stored sensitive data, pivoting to the rest of the network, long-term persistence difficult to detect (no logs of compromised authentication). ServiceNow joins Citrix, Ivanti, and MOVEit in the unenviable pantheon of enterprise platforms massively exploited after a CVE is published.

Ransomware groups actively scan these targets within hours of publication. Unpatched instances are compromised quickly.

Technical Analysis

Exploitation details remain partially undisclosed—a classic responsible disclosure delay. What is established: the flaws affect endpoints accessible without authentication (APIs, management interfaces) and lead to server-side execution with elevated privileges. Three distinct components are affected, multiplying potential attack surfaces.

What to Do Now

Immediate Actions

1. Apply ServiceNow patches immediately—check the official Security Advisory on the support portal. Absolute priority P0.
2. Assess network exposure: Is your instance accessible from the internet without a VPN? If so, deploy WAF and network access restrictions urgently, even before patching.
3. Audit recent access logs: requests to unauthenticated endpoints, unexpected 200 responses on API routes, abnormal high-volume requests.
4. Look for IOCs: new files in application directories, unexpected processes, outgoing connections to unknown IPs.
5. Treat the instance as potentially compromised if it was exposed and unpatched in recent days—perform forensics before restarting in production.
6. Alert your CISO: this is an incident response, not a scheduled maintenance.
