ServiceNow Penetration Testing

ServiceNow secures the platform. You own everything you built on top. Under ServiceNow's shared responsibility model, the platform vendor secures the platform. You own everything you built on it. The custom apps, business rules, ACLs, and integrations your team has shipped contribute to your attack surface. EntruLabs tests all three layers as standard on every ServiceNow penetration test we deliver.

Every engagement includes all three layers

1. Standard web application penetration test. Authentication, session management, injection, and access-control testing against your ServiceNow instance(s). The baseline every reputable security firm performs. Tags: auth & session, injection, access control, OWASP top 10.
2. Known CVE validation. Targeted validation against published ServiceNow CVEs to confirm your instance is patched and not exposed to known exploit paths. Some advisories also require customer-side fixes alongside ServiceNow's patching. We verify those were applied correctly. Tags: published CVEs, patch posture, exploit replay.
3. Whitebox code review (standard scope included). A fixed scope of items you prioritize for a deep-dive review of your custom code and configuration. This is where the shared responsibility model could leave you exposed. Additional scope is available on request. Tags: custom scoped apps, custom code, access to specific data, complex catalog items & flows, integrations.

How an engagement works

1. Scoping call. 30 minutes. We confirm instance count, environments in scope, and targets for the standard whitebox scope, as well as timing. You notify ServiceNow that a pen test is scheduled, as required under their terms of use.
2. Testing. Two-week window on average. All three layers run in parallel: web-app pen test, CVE validation, and whitebox review of your prioritized custom code.
3. Delivery. Written report plus an optional live client portal with replayable PoCs, severity, and a prioritized remediation roadmap your team can action.

The whitebox review's standard scope is a fixed set of items the customer prioritizes from the categories in Layer 03. Additional scope can be added on request.

Why EntruLabs

• Platform-deep testing. All testers are uniquely dual-experienced in ServiceNow architecture and offensive security.
• Reporting & remediation. Replayable PoCs, prioritized remediation roadmap, and optional assistance with remediation.

Recent outcomes

A sample of critical findings from Q3 2025 engagements, in customer-built code (anonymized):

• CRITICAL. An unauthenticated public-facing endpoint returned the full contents of sys_user, exposing PII for every employee in the instance.
• CRITICAL. A ServiceNow integration passed unsanitized input into a mission-critical downstream system, yielding SQL injection against the system of record.
• CRITICAL. A self-registered guest user could chain insecure AJAX-accessible scripts to escalate all the way to full platform admin.
