CVE-2025-22215

Executive Summary

CVE-2025-22215 is a Server-Side Request Forgery (SSRF) vulnerability in VMware Aria Automation. A malicious actor with "Organization Member" access can exploit this flaw to enumerate internal services running on the host or network. The vulnerability carries a CVSS score of 4.3 (Medium), indicating a moderate risk primarily due to the requirement for authenticated access and the limited impact on confidentiality. No public proof-of-concept (PoC) code, exploit-db entries, or nuclei templates are currently available. The EPSS score is 0.0%, suggesting a very low probability of exploitation in the wild at this time. However, the lack of a patch from VMware makes this a significant concern for organizations using the affected product.

Supply Chain & Package Security

This vulnerability is not related to NPM, PyPI, Go, or Ruby packages. It is a proprietary VMware product vulnerability.

CVSS Breakdown & Threat Level

• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
• Base Score: 4.3 (Medium)
• Attack Vector (AV): Network – The vulnerability can be exploited remotely.
• Attack Complexity (AC): Low – No special conditions are required for exploitation.
• Privileges Required (PR): Low – The attacker must have "Organization Member" access.
• User Interaction (UI): None – No user action is needed.
• Scope (S): Unchanged – The exploitation does not affect other components.
• Confidentiality (C): Low – Limited information disclosure (internal service enumeration).
• Integrity (I): None – No data modification is possible.
• Availability (A): None – No denial of service impact.

Threat Level: Medium. The requirement for authenticated access reduces the attack surface, but the potential to map internal networks and services can be a stepping stone for more severe attacks.

Deep Dive & Mechanics

The vulnerability resides in how VMware Aria Automation handles user-supplied URLs or network requests. An authenticated user with "Organization Member" privileges can craft a malicious request that forces the server to make an outbound HTTP request to an arbitrary internal or external address. This SSRF allows the attacker to:

• Enumerate internal services: Identify running services on the host or internal network (e.g., databases, configuration servers, cloud metadata endpoints).
• Bypass firewall restrictions: The request originates from the trusted Aria Automation server, potentially reaching services that are not exposed to the internet.
• Gather information for lateral movement: The enumeration can reveal internal IP addresses, service banners, and potentially sensitive configuration data.

The root cause is likely insufficient validation of user-supplied URLs or hostnames in API endpoints that perform server-side requests (e.g., for integration with external systems, health checks, or proxy functionality). The application does not properly restrict the target of these requests, allowing the attacker to specify internal IP ranges (e.g., 127.0.0.1, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).

Vulnerable vs. Patched Code

Since no official patch or code diff is available, the following is a hypothetical example of the vulnerable and patched code patterns.

Vulnerable Code (Python/Flask example):

@app.route('/api/v1/proxy')
def proxy_request():
    target_url = request.args.get('url')
    # No validation of target_url
    response = requests.get(target_url)
    return response.text

Patched Code (Python/Flask example):

import re
from urllib.parse import urlparse

ALLOWED_DOMAINS = ['api.example.com', 'services.example.com']
BLOCKED_IPS = ['127.0.0.0/8', '10.0.0.0/8', '172.16.0.0/12', '192.168.0.0/16']

def is_safe_url(url):
    parsed = urlparse(url)
    hostname = parsed.hostname
    # Check if hostname is an IP and if it's in blocked ranges
    if re.match(r'^\d+\.\d+\.\d+\.\d+$', hostname):
        import ipaddress
        ip = ipaddress.ip_address(hostname)
        for block in BLOCKED_IPS:
            if ip in ipaddress.ip_network(block):
                return False
    # Check if hostname is in allowed domains
    if hostname not in ALLOWED_DOMAINS:
        return False
    return True

@app.route('/api/v1/proxy')
def proxy_request():
    target_url = request.args.get('url')
    if not is_safe_url(target_url):
        return "Forbidden", 403
    response = requests.get(target_url)
    return response.text

Exploitation & Lab Setup

Red Team

Objective: Enumerate internal services from a compromised "Organization Member" account.

Prerequisites:

• Valid credentials for a user with "Organization Member" role in VMware Aria Automation.
• Network access to the Aria Automation web interface.

Exploitation Steps:

1. Identify SSRF endpoint: Use the application's API documentation or fuzz common endpoints (e.g., /api/v1/proxy, /integration/test, /healthcheck). Look for parameters like url, target, host, or endpoint.

2. Craft a malicious request: Use a tool like curl or Burp Suite to send a request that forces the server to connect to an internal service.

   curl -X GET "https://aria-automation.example.com/api/v1/proxy?url=http://127.0.0.1:8080/admin"
   

3. Enumerate internal services: Iterate through common internal IP addresses and ports.

   for port in 22 80 443 8080 8443 3306 5432 6379 27017; do
       curl -s -o /dev/null -w "%{http_code}" "https://aria-automation.example.com/api/v1/proxy?url=http://10.0.0.1:$port"
   done
   

4. Access cloud metadata endpoints: If the server is hosted in a cloud environment, attempt to access the metadata service.

   curl "https://aria-automation.example.com/api/v1/proxy?url=http://169.254.169.254/latest/meta-data/"
   

Expected Outcome: The attacker receives responses from internal services, revealing their existence, banners, and potentially sensitive data.

Detection & Prevention:

1. Monitor for SSRF patterns: Look for outbound HTTP requests from the Aria Automation server to internal IP ranges (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) or cloud metadata IPs (169.254.169.254).

2. Network segmentation: Ensure the Aria Automation server is isolated from sensitive internal networks. Use firewalls to block outbound traffic to internal IP ranges from the application server.

3. Web Application Firewall (WAF) rules: Deploy WAF rules to block requests containing internal IP addresses or hostnames in URL parameters.

4. Audit logs: Enable detailed logging for all API requests and monitor for unusual patterns, such as repeated requests to different internal IPs.

Lab Setup for Testing:

• Environment: A virtualized VMware Aria Automation instance (version unknown) with a test user account.
• Tools: Burp Suite, curl, netcat, Python.
• Network: A separate internal network with a few simulated services (e.g., a simple HTTP server on 10.0.0.1:8080).

Indicators of Compromise (IOCs)

• Network Traffic:

  • Outbound HTTP requests from the Aria Automation server to internal IP addresses (e.g., 10.x.x.x, 172.16.x.x, 192.168.x.x, 127.0.0.1).
  • Requests to cloud metadata endpoints (169.254.169.254).
  • Unusual patterns of requests to multiple ports on the same internal IP.

• Log Entries:

  • API access logs showing url parameters containing internal IPs or hostnames.
  • Error logs indicating connection attempts to blocked or non-existent internal services.

• File System:

  • Temporary files or cached responses from internal services (if the application stores them).

Remediation & Mitigation

Immediate Actions:

1. Apply vendor patch: Monitor VMware's security advisory page for an official patch. Apply it as soon as it becomes available.
2. Restrict "Organization Member" privileges: Review and minimize the number of users with this role. Consider using a more restrictive role for day-to-day operations.
3. Network segmentation: Place the Aria Automation server in a DMZ with strict outbound firewall rules. Block all outbound traffic to internal IP ranges (RFC 1918) and cloud metadata IPs.
4. Web Application Firewall (WAF): Deploy a WAF in front of Aria Automation with rules to block SSRF attempts (e.g., blocking URL parameters containing internal IPs).
5. Disable unnecessary features: If the SSRF-prone functionality is not required, disable it via configuration or feature flags.

Long-Term Mitigations:

1. Code review: Conduct a thorough code review of all API endpoints that make server-side requests. Implement strict allowlists for allowed destinations.
2. Input validation: Sanitize and validate all user-supplied URLs. Reject any requests containing internal IPs, hostnames, or non-standard ports.
3. Least privilege: Implement role-based access control (RBAC) with granular permissions. Avoid granting "Organization Member" access unless absolutely necessary.
4. Monitoring: Set up alerts for any outbound HTTP requests from the Aria Automation server to suspicious destinations.
