Notes: Affects Dataverse instances with standard configurations; complex permission models may increase risk.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of Dataverse environment, unauthorized access to all data, privilege escalation to system administrator, potential lateral movement to connected systems.

🟠

Likely Case

Unauthorized access to sensitive business data, privilege escalation within Dataverse, potential data exfiltration or modification.

🟢

If Mitigated

Limited impact due to network segmentation, strong authentication controls, and minimal user privileges.

🌐 Internet-Facing: MEDIUM - Exploitation requires network access but also authentication; internet-facing instances increase attack surface.
🏢 Internal Only: HIGH - Internal attackers with valid credentials can exploit this to elevate privileges and access sensitive data.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires authenticated access; exploitation likely involves manipulating authentication mechanisms or session handling.

Check through Microsoft Power Platform admin center or PowerShell: Get-CrmConnection

Verify Fix Applied:

Verify Dataverse version matches or exceeds patched version from Microsoft

📡 Detection & Monitoring

Log Indicators:

  • Unusual authentication patterns
  • Multiple failed login attempts followed by success
  • Privilege escalation events in audit logs

Network Indicators:

  • Unusual API calls to Dataverse endpoints
  • Suspicious authentication traffic patterns
