# DELIVERYPRO APIM SECURITY VULNERABILITY

## Hardcoded Azure API Management Subscription Key Exposure

**Discovery Date:** November 2025  
**Platform:** DeliveryPro Web Portal (https://deliveryproconsole.com/)  
**Severity:** CRITICAL  
**Status:** Reported to Fraud Risk Team & IT Security

---

## EXECUTIVE SUMMARY

During security testing of Purolator's DeliveryPro (also known as PuroLabs) web portal and mobile application ecosystem, a critical vulnerability was discovered: an Azure API Management (APIM) subscription key hardcoded in client-side JavaScript. This key provides unrestricted access to Purolator's entire backend API infrastructure without authentication, IP restrictions, or rate limiting.

**Impact:**

- Extraction of 1,000+ records containing sensitive PII
- Real-time access to active shipment data
- Exposure of 525+ driver records with personal information
- 240 agency business profiles accessible
- Potential for operational data manipulation

**Root Cause:** Client-side secret storage - subscription key embedded in publicly accessible JavaScript file

---

## TECHNICAL DETAILS

### 1. INITIAL DISCOVERY

**Vector:** Client-Side JavaScript Analysis

**Location:** `unminified.js`, line 373660

**Finding:** Azure APIM subscription key hardcoded in JavaScript:

```javascript
// Line 373660 in unminified.js
const APIM_SUBSCRIPTION_KEY = "d3ff8e2a1c4b456789e0f1a2b3c4d5e6"; // Example format
```

**Accessibility:**

- No authentication required to download JavaScript
- Key visible in browser DevTools
- No obfuscation or encryption applied
- Public-facing web application

### 2. DEVELOPER PORTAL ENUMERATION

**Discovery Method:** Azure APIM Developer Portal Analysis

**Step 1: Portal Access**

Navigated to public APIM Developer Portal:

```
https://pl-apim-live.developer.azure-api.net/
```

**Step 2: Configuration File Discovery**

During AAD sign-in flow, observed request to configuration endpoint:

```
GET https://pl-apim-live.developer.azure-api.net/config.json
```

**Response Exposed Management API Details:**

```json
{
  "managementApiUrl": "https://pl-apim-live.management.azure-api.net/subscriptions/000/resourceGroups/000/providers/Microsoft.ApiManagement/service/pl-apim-live",
  "managementApiVersion": "2022-04-01-preview"
}
```

**Step 3: API Surface Enumeration**

Using discovered management API URL, successfully enumerated all APIs:

```http
GET https://pl-apim-live.management.azure-api.net/subscriptions/000/resourceGroups/000/providers/Microsoft.ApiManagement/service/pl-apim-live/apis?api-version=2025-03-01-preview
```

**Result:**

- **21 APIs** discovered
- **95 operations** in Parcels API alone
- Bulk-download routes identified
- Complete API surface mapped

### 3. SUBSCRIPTION KEY VALIDATION

**Test:** Used discovered APIM subscription key ("DeliveryPro Live") against enumerated endpoints

**Result:** SUCCESSFUL AUTHENTICATION - Full access to production data

**No Additional Controls:**

- No IP allowlisting
- No user authentication required
- No rate limiting observed
- No geographic restrictions
- No time-based access controls

## POTENTIAL MANIPULATION ENDPOINTS

### 4.1 Write Operations Identified

During API enumeration, discovered endpoints that could potentially manipulate operational data:

**Parcel Assignment:**

```
POST /api/parcels/assign
PUT /api/parcels/{parcelId}/driver
```

**Driver Notifications:**

```
POST /api/drivers/notify
POST /api/drivers/{driverId}/message
```

**Delivery Status Updates:**

```
PUT /api/parcels/{parcelId}/status
POST /api/parcels/{parcelId}/event
```

**Route Management:**

```
POST /api/routes/create
PUT /api/routes/{routeId}/parcels
DELETE /api/routes/{routeId}
```

**Note:** Write operations were NOT tested to avoid operational disruption and maintain responsible disclosure practices. However, if the subscription key has write permissions, these endpoints could enable:

- Parcel reassignment to unauthorized drivers
- False delivery status updates
- Route manipulation
- Unauthorized notifications
- Data corruption

## PROOF OF CONCEPT

### 6.1 Reproduction Steps

**Prerequisites:**

- Web browser with DevTools
- HTTP client (curl, Postman, etc.)

**Step 1: Extract APIM Subscription Key**

```bash
# Access DeliveryPro web portal
curl https://deliveryproconsole.com/

# Extract JavaScript files
curl https://deliveryproconsole.com/static/js/unminified.js > unminified.js

# Search for subscription key
grep -n "subscription" unminified.js
# Found at line 373660: subscription key visible
```

**Step 2: Discover Management API**

```bash
# Access APIM Developer Portal
curl https://pl-apim-live.developer.azure-api.net/config.json

# Response contains:
# "managementApiUrl": "https://pl-apim-live.management.azure-api.net/..."
# "managementApiVersion": "2022-04-01-preview"
```

**Step 3: Enumerate API Surface**

```bash

## ROOT CAUSE ANALYSIS

### 7.1 Primary Vulnerability: Client-Side Secret Storage

**Problem:**
Azure APIM subscription keys are meant to be server-side secrets. Embedding them in client-side JavaScript makes them publicly accessible to anyone who views the page source.

**Why This Happened:**

- Developers needed to call APIs from frontend
- Chose convenience over security
- Likely misunderstood APIM subscription key security model
- No code review caught the issue

**Correct Architecture:**

```
Browser → Backend Proxy → APIM (with subscription key)
```

**Vulnerable Architecture:**

```
Browser → APIM (subscription key in JavaScript)
```

### 7.2 Secondary Vulnerability: No Additional Access Controls

**Missing Controls:**

- No user authentication on API endpoints
- No IP allowlisting for subscription key
- No rate limiting per key
- No geographic restrictions
- No time-based access windows

**Result:** Subscription key alone grants full access - no defense in depth.

### 7.3 Tertiary Vulnerability: Excessive Permissions

**Problem:**
Subscription key appears to have read access to ALL APIs, including:

- Customer PII
- Driver records
- Agency data
- Operational data

**Principle of Least Privilege Violated:**

- Frontend only needs specific endpoints
- Key grants access to entire API surface
- No scope limitation

### 7.4 Configuration Exposure

**Problem:**
APIM Developer Portal's `config.json` publicly exposes management API details, enabling:

- Complete API surface enumeration
- Discovery of undocumented endpoints
- Understanding of API structure

**Should Be:**

- Management API URL should be internal only
- Developer Portal should use authenticated session
- Configuration should not be public

---

## COMPARISON WITH MOBILE APP VULNERABILITY

### 8.1 Common Patterns

Both DeliveryPro Web Portal and Purolator Mobile App exhibit similar security architecture flaws:

| Aspect                | Mobile App                            | Web Portal                  |
| --------------------- | ------------------------------------- | --------------------------- |
| **Secret Storage**    | AES-256 encrypted in Android Keystore | Plaintext in JavaScript     |
| **Root Cause**        | Runtime memory accessible             | Client-side code accessible |
| **Bypass Complexity** | High (requires Frida, rooted device)  | Low (view page source)      |
| **Exposed Secrets**   | Tracking API key, Salesforce OAuth    | APIM subscription key       |
| **Access Control**    | None after decryption                 | None with key               |
| **Impact**            | API access, credential extraction     | Massive PII exfiltration    |

### 8.2 Key Differences

**Mobile App:**

- Requires technical expertise (Frida, root)
- Targets individual device
- AES-256 encryption (strong, but bypassable)
- Architectural limitation of client-side security

**Web Portal:**

- Requires zero expertise (view source)
- Affects all users
- No encryption (plaintext secret)
- Fundamental security mistake

**Verdict:** Web portal vulnerability is MORE severe due to ease of exploitation.

### 8.3 Shared Recommendations

**For Both Platforms:**

1. Move all secrets server-side
2. Implement backend proxy pattern
3. Use temporary, scoped tokens
4. Add device/user attestation
5. Implement comprehensive monitoring

5. **Timeline:** Immediate action required (key revocation within 24 hours)

**Comparison with Mobile App:**
While the mobile app vulnerability required technical sophistication (Frida, rooted device), the web portal vulnerability requires only viewing page source. This makes it accessible to any attacker and significantly more severe.

**Positive Note:**
The development team's implementation of business logic and features is sound. This is an architectural/security design issue, not a reflection of coding quality. With proper security controls in place, the platform can be secured effectively.
