CVE-2025-22222

Executive Summary

CVE-2025-22222 is an information disclosure vulnerability in VMware Aria Operations. A malicious user with non-administrative privileges can exploit this vulnerability to retrieve credentials for an outbound plugin if a valid service credential ID is known. The vulnerability has a CVSS score of 7.7 (High), indicating significant confidentiality impact. No public proof-of-concept (PoC) or exploit code is currently available, and the patch status is unknown. The EPSS score is 0.0%, suggesting low exploitation activity in the wild at this time.

CVSS Breakdown & Threat Level

• CVSS Score: 7.7 (High)
• Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
• Attack Vector: Network (AV:N) – The vulnerability can be exploited remotely.
• Attack Complexity: Low (AC:L) – No special conditions are required.
• Privileges Required: Low (PR:L) – The attacker needs non-administrative access.
• User Interaction: None (UI:N) – No user action is required.
• Scope: Unchanged (S:U) – The impact is confined to the vulnerable component.
• Confidentiality Impact: High (C:H) – Credentials for outbound plugins can be exposed.
• Integrity Impact: None (I:N) – No data modification is possible.
• Availability Impact: None (A:N) – No denial of service.

Threat Level: High. The ability to retrieve credentials with low privileges makes this a serious risk for organizations using VMware Aria Operations.

Deep Dive & Mechanics

The vulnerability resides in the credential management functionality of VMware Aria Operations. The application exposes an API endpoint that allows retrieval of stored credentials for outbound plugins. The flaw is that this endpoint does not properly enforce authorization checks for non-administrative users. If an attacker knows a valid service credential ID (which may be guessable or enumerable), they can make a crafted API request to retrieve the associated credentials in plaintext.

The attack flow:

1. The attacker authenticates as a non-administrative user.
2. The attacker enumerates or guesses service credential IDs (e.g., sequential IDs).
3. The attacker sends a GET request to the vulnerable endpoint (e.g., /api/credentials/{id}).
4. The server returns the credential details, including the password or secret, without proper authorization.

This is a classic case of Insecure Direct Object Reference (IDOR) combined with missing access control checks.

Vulnerable vs. Patched Code

Since no patch details are available, the following is a hypothetical comparison based on the vulnerability description.

Vulnerable Code (Conceptual):

@app.route('/api/credentials/<credential_id>', methods=['GET'])
def get_credential(credential_id):
    # No privilege check
    credential = db.query("SELECT * FROM credentials WHERE id = ?", credential_id)
    if credential:
        return jsonify(credential)
    else:
        return "Not found", 404

Patched Code (Conceptual):

@app.route('/api/credentials/<credential_id>', methods=['GET'])
def get_credential(credential_id):
    # Check if user has admin privileges
    if not current_user.is_admin:
        return "Forbidden", 403
    credential = db.query("SELECT * FROM credentials WHERE id = ?", credential_id)
    if credential:
        return jsonify(credential)
    else:
        return "Not found", 404

The patch adds an authorization check to ensure only administrators can access credential details.

Exploitation & Lab Setup

Red Team

Prerequisites:

• Access to a VMware Aria Operations instance with a non-administrative user account.
• Knowledge of a valid credential ID (can be brute-forced if IDs are sequential).

Exploitation Steps:

1. Authenticate to the VMware Aria Operations web interface.
2. Obtain a session token (e.g., via cookies or API token).
3. Enumerate credential IDs by sending requests to /api/credentials/1, /api/credentials/2, etc.
4. For each ID, check the response. If the response contains credential data (e.g., "password": "..."), the ID is valid.
5. Extract the credentials for use in further attacks (e.g., lateral movement).

Example cURL command:

curl -X GET "https://target-vrops.example.com/api/credentials/42" \
  -H "Authorization: Bearer <session_token>"

Blue Team

Detection:

• Monitor for unusual API requests to /api/credentials/ endpoints from non-administrative users.
• Alert on sequential or rapid enumeration of credential IDs.
• Correlate with authentication logs to identify the source user.

Prevention:

• Implement strict access controls on credential management APIs.
• Use role-based access control (RBAC) to restrict credential viewing to administrators.
• Apply rate limiting on API endpoints to slow down enumeration attempts.
• Log all access to credential endpoints and review regularly.

Hunting:

• Search for HTTP 200 responses to /api/credentials/ from non-admin users.
• Look for patterns of sequential ID requests in web server logs.

Indicators of Compromise (IOCs)

• Network: HTTP GET requests to /api/credentials/{integer} from non-administrative IPs.
• Logs: Successful retrieval of credential data by a user without admin privileges.
• File: Unusual access to credential storage files (if applicable).
• Behavior: Rapid sequential requests to credential API endpoints.

Remediation & Mitigation

Immediate Actions:

1. Isolate affected VMware Aria Operations instances from untrusted networks.
2. Review user privileges and remove unnecessary non-administrative accounts.
3. Monitor logs for any signs of exploitation.

Long-term Fixes:

• Apply vendor patches as soon as they become available.
• Implement network segmentation to limit access to management interfaces.
• Enable multi-factor authentication (MFA) for all users.
• Conduct a security audit of API endpoints for proper authorization.

Workarounds (if patching is not possible):

• Disable the credential API endpoint via web server configuration (e.g., block /api/credentials/).
• Use a Web Application Firewall (WAF) to block requests to credential endpoints from non-admin IPs.
