CVE-2022-22972 Overview
CVE-2022-22972 is a critical authentication bypass vulnerability affecting VMware Workspace ONE Access, Identity Manager, and vRealize Automation products. The vulnerability specifically impacts local domain users and allows a malicious actor with network access to the management UI to obtain administrative access without requiring any authentication credentials.
This vulnerability represents a severe security risk for organizations utilizing VMware's identity management and automation solutions. The ability to bypass authentication entirely means that attackers can gain full administrative control over affected systems, potentially leading to complete infrastructure compromise.
Critical Impact
Unauthenticated remote attackers with network access to the web UI can gain full administrative privileges, enabling complete system takeover and potential lateral movement across enterprise VMware environments.
Affected Products
- VMware Workspace ONE Access (versions 20.10.0.0, 20.10.0.1, 21.08.0.0, 21.08.0.1)
- VMware Identity Manager (versions 3.3.3, 3.3.4, 3.3.5, 3.3.6)
- VMware vRealize Automation (version 7.6)
- VMware Cloud Foundation (versions 3.x and 4.x)
- VMware vRealize Suite Lifecycle Manager (versions 8.0 through 8.8)

Technical Details for CVE-2022-22972
Vulnerability Analysis
This authentication bypass vulnerability affects the local domain user authentication mechanism within VMware's identity management products. The flaw allows attackers to circumvent the normal authentication workflow when accessing the web-based management interface. Once exploited, an attacker gains administrative privileges equivalent to a legitimately authenticated administrator.
The vulnerability is particularly dangerous because it requires no prior authentication or valid credentials. An attacker simply needs network connectivity to the management interface to exploit this flaw. Given that VMware Workspace ONE Access and Identity Manager are often deployed as central authentication hubs for enterprise environments, successful exploitation could provide attackers with a foothold to access numerous connected systems and applications.
Root Cause
The root cause of CVE-2022-22972 lies in improper authentication validation logic within the affected VMware products. When processing authentication requests for local domain users through the web UI, the application fails to properly verify that valid credentials have been provided before granting administrative access. This authentication logic flaw enables attackers to manipulate authentication requests in a way that bypasses credential verification entirely.
Attack Vector
The attack vector for this vulnerability is network-based, targeting the web management interface of affected VMware products. An attacker positioned on the same network as the vulnerable system, or with access through the internet if the management interface is exposed, can craft malicious requests to the UI that exploit the authentication bypass.
The exploitation flow involves:
- Attacker identifies a vulnerable VMware Workspace ONE Access, Identity Manager, or vRealize Automation instance
- Attacker sends specially crafted requests to the web management interface
- The authentication validation is bypassed due to the logic flaw
- Attacker receives administrative session access without providing valid credentials
- With admin access, attacker can modify configurations, create backdoor accounts, or pivot to connected systems
Organizations should note that administrative interfaces for these products should never be exposed to untrusted networks. However, even internal network exposure presents significant risk given the ease of exploitation.
Detection Methods for CVE-2022-22972
Indicators of Compromise
- Unexpected administrative sessions or logins in VMware Workspace ONE Access, Identity Manager, or vRealize Automation logs
- Creation of new administrator accounts without corresponding authorized change requests
- Unusual configuration changes to identity federation settings or connected applications
- Authentication log entries showing successful admin access without corresponding credential verification events
Detection Strategies
- Monitor authentication logs for administrative access patterns that lack proper credential validation sequences
- Implement network monitoring to detect unusual traffic patterns to VMware management interfaces
- Deploy SIEM rules to alert on administrative actions from unexpected source IP addresses or outside normal business hours
- Review audit logs for bulk configuration exports or changes to authentication policies
Monitoring Recommendations
- Enable verbose logging on all VMware identity management products and forward logs to a centralized SIEM
- Configure alerts for any new administrator account creation or privilege escalation events
- Monitor network traffic to management interfaces for anomalous request patterns
- Implement regular audits of administrative accounts and access logs for signs of unauthorized access
How to Mitigate CVE-2022-22972
Immediate Actions Required
- Apply VMware security patches immediately to all affected products as documented in VMware Security Advisory VMSA-2022-0014
- Restrict network access to management interfaces using firewall rules and network segmentation
- Audit all administrative accounts for unauthorized changes or newly created accounts
- Review authentication logs for signs of exploitation prior to patching
- Consider temporary isolation of affected systems if immediate patching is not possible
Patch Information
VMware has released security patches addressing CVE-2022-22972. Organizations should consult the VMware Security Advisory VMSA-2022-0014 for specific patch versions and installation instructions for their deployed products.
The affected product versions and their corresponding patches include updates for:
- VMware Workspace ONE Access versions 20.10.0.0, 20.10.0.1, 21.08.0.0, 21.08.0.1
- VMware Identity Manager versions 3.3.3, 3.3.4, 3.3.5, 3.3.6
- VMware vRealize Automation version 7.6
- VMware Cloud Foundation versions 3.x and 4.x
- VMware vRealize Suite Lifecycle Manager versions 8.0 through 8.8
Workarounds
- Implement strict network segmentation to limit access to management interfaces to authorized administrator workstations only
- Deploy a web application firewall (WAF) in front of the management interface with rules to detect and block suspicious authentication attempts
- Enable multi-factor authentication (MFA) where supported to add an additional layer of protection
- Disable local domain user authentication if not required and rely solely on federated identity providers
# Network segmentation example using iptables to restrict management interface access
# Replace 192.168.1.0/24 with your authorized admin network
iptables -A INPUT -p tcp --dport 443 -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
