CVE-2022-23292 Overview
CVE-2022-23292 is a spoofing vulnerability affecting Microsoft Power BI, specifically targeting the Microsoft On-premises Data Gateway component. This vulnerability allows an authenticated attacker with network access to potentially impersonate legitimate entities or manipulate data representations within the Power BI ecosystem. The spoofing nature of this vulnerability could enable attackers to deceive users or systems into trusting malicious content as legitimate.
Critical Impact
Authenticated attackers may exploit this spoofing vulnerability to manipulate data representations or impersonate trusted entities within Microsoft Power BI environments, potentially leading to data integrity issues and user deception.
Affected Products
- Microsoft On-premises Data Gateway (all versions prior to patch)
- Microsoft Power BI environments utilizing On-premises Data Gateway
- Enterprise deployments with hybrid cloud-to-on-premises data connectivity

Technical Details for CVE-2022-23292
Vulnerability Analysis
This spoofing vulnerability exists within the Microsoft On-premises Data Gateway, a critical component that enables secure data transfer between on-premises data sources and Microsoft cloud services including Power BI. The vulnerability requires an attacker to have low-level privileges and network access to the target system, combined with user interaction for successful exploitation.
The attack complexity is considered high, meaning specific conditions must be met for exploitation to succeed. When successfully exploited, the vulnerability can result in limited confidentiality and integrity impacts without affecting system availability. The spoofing nature of this flaw means attackers could potentially present falsified information as authentic, undermining trust in data visualizations and reports.
Root Cause
The root cause of CVE-2022-23292 stems from insufficient validation mechanisms within the On-premises Data Gateway component. While Microsoft has not disclosed specific technical details (classified as NVD-CWE-noinfo), spoofing vulnerabilities typically arise from inadequate verification of data origin, improper identity validation, or missing integrity checks on transmitted content. In the context of a data gateway, this could involve weaknesses in how the gateway authenticates or validates communication between on-premises data sources and cloud services.
Attack Vector
The attack vector for CVE-2022-23292 is network-based, requiring the attacker to have authenticated access to the target environment. Successful exploitation involves:
- Network Access: The attacker must be positioned on the network where the On-premises Data Gateway operates
- Authentication: Low-level privileges are required, meaning the attacker needs valid credentials
- User Interaction: A victim user must interact with the spoofed content for the attack to fully succeed
- Timing Conditions: High attack complexity suggests specific environmental or timing conditions must align
The spoofing attack could manifest through manipulation of data representations displayed in Power BI dashboards or reports, potentially causing users to make decisions based on falsified information.
Detection Methods for CVE-2022-23292
Indicators of Compromise
- Unusual authentication patterns or unexpected user sessions connecting to the On-premises Data Gateway
- Anomalous data transfer patterns between on-premises sources and Power BI cloud services
- Unexpected modifications to gateway configurations or connection strings
- User reports of suspicious or inconsistent data in Power BI reports and dashboards
Detection Strategies
- Monitor On-premises Data Gateway logs for authentication anomalies and unexpected connection attempts
- Implement network monitoring to detect unusual traffic patterns between gateway components and cloud endpoints
- Enable audit logging for all Power BI administrative actions and data refresh activities
- Deploy endpoint detection solutions to monitor gateway server processes and network communications
Monitoring Recommendations
- Configure alerting for failed authentication attempts against the On-premises Data Gateway
- Establish baseline behavior for gateway traffic patterns and alert on deviations
- Review Power BI service activity logs regularly for signs of content manipulation or unauthorized access
- Integrate gateway logs with SIEM solutions for centralized correlation and analysis
How to Mitigate CVE-2022-23292
Immediate Actions Required
- Update Microsoft On-premises Data Gateway to the latest patched version available from Microsoft
- Review and audit all user accounts with access to the On-premises Data Gateway, removing unnecessary privileges
- Verify gateway configurations and ensure secure communication channels are properly configured
- Assess the security posture of network segments where the gateway operates
Patch Information
Microsoft has addressed this vulnerability through security updates. Organizations should consult the Microsoft Security Advisory for specific patch details and download the latest version of the On-premises Data Gateway from Microsoft's official download center. Ensure all gateway instances in your environment are updated to maintain consistent protection.
Workarounds
- Restrict network access to the On-premises Data Gateway to only trusted IP ranges and authorized users
- Implement additional authentication controls such as multi-factor authentication for gateway administrators
- Enable enhanced logging and monitoring while awaiting patch deployment
- Consider temporarily isolating gateway services in high-security environments until patches can be applied
# Verify On-premises Data Gateway version
# Run this PowerShell command on the gateway server to check current version
Get-WmiObject -Class Win32_Product | Where-Object { $_.Name -like "*On-premises data gateway*" } | Select-Object Name, Version
# Review gateway service status
Get-Service -Name "PBIEgwService" | Format-List *
