CVE-2025-69907

Executive Summary

CVE-2025-69907 is an unauthenticated information disclosure vulnerability in Newgen OmniDocs, a document management and workflow automation platform. The flaw resides in the /omnidocs/GetListofCabinet API endpoint, which lacks authentication and access control mechanisms. A remote, unauthenticated attacker can query this endpoint to retrieve sensitive internal configuration data, including cabinet names and database-related metadata. This exposure allows for unauthorized enumeration of backend deployment details, which can be leveraged to plan further targeted attacks against the organization's infrastructure.

The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function) and carries a CVSS v3.1 base score of 7.5 (High), with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. The attack complexity is low, requires no privileges or user interaction, and impacts confidentiality at a high level. No public exploit code or Nuclei template has been released at this time, but the vulnerability is considered publicly known due to the NVD description.

Supply Chain & Package Security

This vulnerability is not related to an NPM, PyPI, Go, or Ruby package. It is a proprietary enterprise application (Newgen OmniDocs) and does not fall under the supply chain package security scope.

CVSS Breakdown & Threat Level

• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
• Base Score: 7.5 (High)
• Attack Vector (AV): Network – The vulnerability is exploitable remotely over the network.
• Attack Complexity (AC): Low – No special conditions or race conditions are required.
• Privileges Required (PR): None – No authentication is needed.
• User Interaction (UI): None – No user action is required.
• Scope (S): Unchanged – The vulnerable component and the impacted component are the same.
• Confidentiality (C): High – Sensitive configuration data (cabinet names, database metadata) is exposed.
• Integrity (I): None – No data modification is possible.
• Availability (A): None – No denial of service impact.

Threat Level: High. The ease of exploitation (no auth, low complexity) combined with the potential for reconnaissance makes this a critical finding for any organization using Newgen OmniDocs.

Deep Dive & Mechanics

The /omnidocs/GetListofCabinet endpoint is designed to return a list of document cabinets and associated metadata. In a properly secured implementation, this endpoint would require authentication (e.g., a valid session token or API key) and enforce access control to ensure only authorized users can enumerate cabinets. However, in vulnerable versions of Newgen OmniDocs, the endpoint does not validate any credentials or session tokens.

How the vulnerability works:

1. An attacker sends an HTTP GET request to https://target-omnidocs-instance/omnidocs/GetListofCabinet.
2. The server processes the request without checking for authentication headers or session cookies.
3. The response contains a JSON or XML payload listing all configured cabinets, including internal names, database connection strings (or references), and other metadata.
4. The attacker can parse this information to understand the backend architecture, database types, and naming conventions.

Potential impact of disclosed information:

• Cabinet names may reveal business units, project codes, or sensitive document categories.
• Database metadata (e.g., server names, table prefixes) can be used to craft SQL injection or other database-level attacks.
• Knowledge of internal naming conventions aids in social engineering or brute-force attacks on other endpoints.

Vulnerable vs. Patched Code

Since no official patch or source code diff is available, the following is a conceptual comparison based on the vulnerability description.

Vulnerable Code (Conceptual):

# Vulnerable endpoint - no authentication check
@app.route('/omnidocs/GetListofCabinet', methods=['GET'])
def get_cabinet_list():
    cabinets = db.query("SELECT name, metadata FROM cabinets")
    return jsonify(cabinets)

Patched Code (Conceptual):

# Patched endpoint - authentication required
@app.route('/omnidocs/GetListofCabinet', methods=['GET'])
@require_auth  # decorator that validates session token
def get_cabinet_list():
    cabinets = db.query("SELECT name, metadata FROM cabinets")
    return jsonify(cabinets)

The patch would involve adding an authentication middleware or decorator that checks for a valid session token or API key before processing the request. Additionally, access control checks should be implemented to ensure the authenticated user has permission to view cabinet lists.

Exploitation & Lab Setup

Red Team (Offensive)

Lab Setup:

• Deploy a vulnerable instance of Newgen OmniDocs (version unknown, but any version without the patch).
• Ensure the /omnidocs/GetListofCabinet endpoint is accessible without authentication.

Exploitation Steps:

1. Identify the target OmniDocs instance (e.g., via Shodan or manual discovery).
2. Send a GET request to the vulnerable endpoint:

   curl -X GET http://target-omnidocs-instance/omnidocs/GetListofCabinet
   

3. Parse the response to extract cabinet names and metadata.
4. Use the disclosed information to plan further attacks (e.g., SQL injection on database endpoints, brute-force on admin panels).

Example Output (Simulated):

{
  "cabinets": [
    {
      "name": "HR_Confidential",
      "database": "omnidocs_db",
      "server": "db01.internal.corp"
    },
    {
      "name": "Finance_2025",
      "database": "omnidocs_fin",
      "server": "db02.internal.corp"
    }
  ]
}

Blue Team (Defensive)

Detection:

• Monitor for requests to /omnidocs/GetListofCabinet from unauthenticated sources.
• Alert on any response containing cabinet names or database metadata.
• Correlate with other reconnaissance patterns (e.g., directory brute-forcing).

Hunting:

• Search web server logs for GET /omnidocs/GetListofCabinet entries.
• Look for anomalous IPs making multiple requests to this endpoint.
• Check for subsequent attacks targeting database endpoints or admin interfaces.

Indicators of Compromise (IOCs)

• Network IOCs:
  • HTTP GET requests to /omnidocs/GetListofCabinet without authentication headers.
  • Responses containing JSON/XML with keys like cabinet, database, server, metadata.
• File IOCs:
  • Web server logs showing repeated access to the vulnerable endpoint.
• Behavioral IOCs:
  • Unusual enumeration of cabinet names followed by attempts to access other API endpoints.

Remediation & Mitigation

Immediate Actions:

1. Restrict Network Access: Block external access to the /omnidocs/GetListofCabinet endpoint using a web application firewall (WAF) or reverse proxy.
2. Implement Authentication: Add authentication checks to the endpoint. Ensure only authenticated users with proper roles can access cabinet lists.
3. Apply Input Validation: Even after authentication, validate that the user has permission to view the requested data.

Long-Term Fixes:

• Contact Newgen for an official patch or upgrade to a patched version.
• Conduct a security audit of all API endpoints to ensure consistent authentication and authorization.
• Implement logging and monitoring for all API access, especially for endpoints that expose sensitive metadata.

Workarounds:

• If patching is not immediately possible, disable the endpoint entirely by modifying the application configuration or using a reverse proxy to return a 403 Forbidden for requests to /omnidocs/GetListofCabinet.
