ServiceNow (SNOW) is a critical platform for IT and helpdesk workflows in enterprises, but it’s also a common source of secret leaks. API keys, credentials, and sensitive data often get exposed in tickets, knowledge bases (KBs), or file attachments. In Part 1 of Entro’s blog series, five real-world incidents highlight how secrets and non-human identity (NHI) tokens leaked from ServiceNow due to misconfigurations, stolen credentials, and remote code execution (RCE) vulnerabilities.

Leaking Tickets: Secrets Exposure in ServiceNow (Part 1)
You Should Know: Detecting & Preventing ServiceNow Secret Leaks
1. Identifying Misconfigured KBs
ServiceNow KBs can inadvertently expose secrets if permissions are misconfigured. Use these Linux commands to scan for exposed data:
Use curl to check KB accessibility (replace URL) curl -v "https://<instance>.service-now.com/kb_view.do?sysparm_article=KB12345" Search for API keys in logs grep -rE "(apikey|secret|token|password)" /var/log/servicenow/
2. Scanning Attachments for Secrets
Files attached to tickets may contain hardcoded credentials. Use `pdfgrep` or `strings` to extract text:
Extract text from PDFs in a directory
pdfgrep -i "password|apikey" /path/to/attachments/.pdf
Search for secrets in binary files
strings .docx | grep -E "([A-Za-z0-9]{32})"
3. Detecting RCE Vulnerabilities
Some ServiceNow CVEs allow RCE. Test for vulnerabilities using:
Check ServiceNow version curl -I "https://<instance>.service-now.com" | grep "X-SN-Version" Use nmap to scan for open ports nmap -sV --script vuln <servicenow-instance-ip>
4. Monitoring for Exposed Credentials
Use `git-secrets` or `truffleHog` to detect secrets in code snippets pasted in tickets:
Install truffleHog pip install trufflehog Scan a Git repo for secrets trufflehog git --repo-url https://github.com/example/repo.git
5. Automating Secret Detection in ServiceNow
Deploy a Python script to monitor SNOW APIs for leaked secrets:
import requests
SNOW_INSTANCE = "https://<instance>.service-now.com"
API_KEY = "your_api_key"
response = requests.get(
f"{SNOW_INSTANCE}/api/now/table/kb_knowledge",
headers={"Authorization": f"Bearer {API_KEY}"}
)
if "password" in response.text:
print("Secret leak detected!")
What Undercode Say
ServiceNow is a goldmine for attackers if secrets are mishandled. Enterprises must enforce strict access controls, automate secret scanning, and patch CVEs promptly. The upcoming Part 2 will cover remediation strategies—stay tuned.
Prediction
As ServiceNow adoption grows, secret leaks will increase unless organizations implement proactive monitoring and least-privilege access. AI-driven secret detection tools will become essential in 2024.
Expected Output:
- Leaking Tickets: ServiceNow Secrets Exposure Incidents
- URL: https://entro.security/blog/leaking-tickets-secrets-exposure-in-servicenow-part-1/
- Commands:
curl,grep,pdfgrep,nmap, `trufflehog` - Scripts: Python API monitoring
- Conclusion: Proactive secret management is critical.
- Prediction: AI-based secret detection will rise in 2024.
