Executive Summary

-

A comprehensive 8-stage vulnerability discovery audit was conducted against the ShopDB manufacturing asset management system using the Glasswing methodology (Recon, Hunt, Validate, Gapfill, Dedupe, Trace, Feedback, Report). The audit discovered 7 confirmed exploitable vulnerabilities across authentication, authorization, cryptography, and resource management domains.

Confirmed Vulnerabilities

- - -
-
- HIGH - CWE-345 - 1. Agent Binary Injection -
-
-
-
Description
-

The agent binary upload endpoint accepts ANY Windows PE executable without code signing or publisher verification. A compromised operator with endpoints.agentpackage + endpoints.agentupdate permissions can upload and deploy malicious binaries that execute as SYSTEM across the entire Windows endpoint fleet.

-
- -
-
Location
-

plugins/endpoints/api/agentupload.py:127-131

-
- -
-
Attack Chain
-
    -
  1. POST /api/endpoints/siteagent/binaries/agent with malicious PE (only checks for "MZ" header)
    2. -
  2. Binary staged to instance/siteagent/agent/<version>/shopdbagent.exe
    3. -
  3. Packaged as Application object in database
    4. -
  4. POST /api/endpoints/<asset_id>/agentupgrade to push to endpoints
    5. -
  5. PowerShell script executes with Unblock-File (bypasses SmartScreen) and runs as SYSTEM
    6. -
-
- -
-
Vulnerable Code
- 
def looks_like_pe(data):
-    """Whether data begins with the Windows PE 'MZ' magic."""
-    return len(data) >= 2 and data[:2] == _PE_MAGIC
-
- -
-
Impact
-
    -
  • Complete fleet compromise
    • -
  • SYSTEM-level code execution on all Windows endpoints
    • -
  • Persistence via Windows service replacement
    • -
  • Active bypass of OS-level protections (SmartScreen)
    • -
-
- -
-
Remediation
-
    -
  • Immediate: Implement Authenticode signature verification
    • -
  • Short-term: Maintain SHA256 whitelist of approved binaries
    • -
  • Long-term: Implement two-person rule (separate upload/deploy permissions)
    • -
  • Defense-in-depth: Remove Unblock-File from upgrade script
    • -
-
-
-
- - -
-
- HIGH - CWE-204 - 2. Account Enumeration via Lockout Disclosure -
-
-
-
Description
-

The login endpoint leaks valid usernames through observable HTTP status code and message differences. Locked accounts return HTTP 403 "Account is locked", while invalid usernames return HTTP 401 "Invalid username or password".

-
- -
-
Location
-

shopdb/core/api/auth.py:102-107

-
- -
-
Attack Vector
-
    -
  1. Make 5-6 failed login attempts with candidate username
    2. -
  2. Observe response: 401 β†’ 403 transition indicates valid username
    3. -
  3. Per-IP rate limiting (30 req/5min) allows ~5 username tests per window per IP
    4. -
-
- -
-
Impact
-
    -
  • Username enumeration enables targeted password attacks
    • -
  • Reduces credential brute-force search space
    • -
  • Undermines username anonymity security assumption
    • -
-
- -
-
Remediation
-
    -
  • Always return HTTP 401 "Invalid username or password" regardless of account state
    • -
  • Enforce lockout post-password-check to eliminate timing differences
    • -
  • Implement constant-time response strategy
    • -

-
- - -
-
- HIGH - CWE-208 - 3. Collector API Key Timing Attack -
-
-
-
Description
-

Collector API key authentication uses Python's == operator for string comparison instead of constant-time comparison (hmac.compare_digest). This allows byte-by-byte extraction of COLLECTOR_API_KEY via timing side-channel attacks.

-
- -
-
Location
-

shopdb/core/api/collector.py:135-137

-
- -
-
Vulnerable Code
- 
# Line 135 - Non-constant-time comparison
-if expected_key and api_key == expected_key \
-        and not _env_fallback_disabled(pluginname):
-    return None
-
- -
-
Correct Usage (Found Elsewhere)
- 
# setup.py:65, usb plugin, endpoints plugin
-if hmac.compare_digest(expected, provided):
-    # Constant-time comparison
-
- -
-
Impact
-
    -
  • Full API key extraction enables unauthenticated access to collector endpoints
    • -
  • Create/update assets without authentication
    • -
  • Inject false telemetry data
    • -
-
- -
-
Remediation
- 
import hmac
-# Replace line 135 with:
-if expected_key and hmac.compare_digest(api_key, expected_key) \
-        and not _env_fallback_disabled(pluginname):
-    return None
-
-
-
- - -
-
- MEDIUM - CWE-613 - 4. Refresh Token Non-Rotation -
-
-
-
Description
-

The /refresh endpoint does not rotate refresh tokens when issuing new access tokens. A compromised refresh token remains valid for 30 days and can be reused unlimited times.

Impact
-
    -
  • Stolen refresh token provides 30-day persistent access

Remediation

- MEDIUM - CWE-770 - 5. Token Refresh Rate Limit Bypass -
-
-
-
Description
-

The /api/auth/refresh endpoint lacks rate limiting. In contrast, /api/auth/login implements fixed-window rate limiting (30 req/5min). Successfully executed 100 token refresh requests in 3.8 seconds (26.3 req/s).

- LOW - CWE-362 - 7. Race Condition in Event Deduplication -
-
-
-
Description
-

Event deduplication check-then-insert (TOCTOU) race allows duplicate EndpointEvent records. Concurrent collector POSTs can both bypass the deduplication check, causing IntegrityError that aborts the entire transaction and loses ALL telemetry in the batch.

⚠️ Unvalidated Findings - Hunt Round 4

-

- Security Audit - September 12, 2026
- Budget exhausted before adversarial validation could complete -

-
- -
- ⚠️ IMPORTANT: These findings have NOT been adversarially validated -

These 40 potential vulnerabilities were discovered in Hunt Round 4 but were not validated due to budget exhaustion ($60.42 of $40.00 budget spent). Based on historical validation rates from Rounds 1-3:

-
    -
  • Expected false positive rate: ~80% (29 of 36 findings rejected in Rounds 1-3)
    • -
  • Estimated real vulnerabilities: 6-8 of these 40
    • -
  • Validation cost: $15-20 additional
    • -
-

Recommendation: Budget for validation round or manually review based on priority.

Validation Approach

- -
-

Option 1: Automated Validation (Recommended)

-

Resume the audit with additional budget to complete adversarial validation:

-
    -
  • Cost: $15-20 additional
    • -
  • Time: ~30-45 minutes
    • -
  • Expected outcome: 6-8 confirmed vulnerabilities, 32-34 rejected as false positives
    • -
  • Command: python audit.py --resume --budget 80
    • -
-
- -
-

Option 2: Manual Review by Priority

-

Review findings manually in priority order:

-
    -
  1. High Priority: File upload validation (8 findings) - Similar to confirmed HIGH severity vuln #1
    2. -
  2. Medium Priority: Rate limiting gaps (7 findings) - Similar to confirmed MEDIUM severity vuln #5
    3. -
  3. Medium Priority: Token management (3 findings) - Similar to confirmed MEDIUM severity vuln #4
    4. -
  4. Low Priority: Race conditions (6 findings) - Similar to confirmed LOW severity vuln #7
    5. -
  5. Low Priority: Timing attacks (2 findings), Info disclosure (1 finding)
    6. -
-
- -
-

Option 3: Accept Risk

-

Focus remediation efforts on the 7 confirmed vulnerabilities only. The unvalidated findings can be addressed in future audit cycles. This is reasonable if:

-
    -
  • Budget constraints prevent additional validation
    • -
  • The 7 confirmed vulnerabilities provide sufficient work backlog
    • -
  • Risk tolerance accepts potential false negatives (missing 6-8 real vulnerabilities)
    • -
