⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could map all user accounts, gather personal identifiable information (PII), and use this intelligence for targeted attacks, credential stuffing, or identity theft.

🟠

Likely Case

Attackers will enumerate valid user accounts and gather partial personal information, enabling follow-on attacks like phishing or brute force attempts.

🟢

If Mitigated

With proper access controls and monitoring, impact is limited to information disclosure without direct system compromise.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

CWE-200 typically involves simple information leakage vulnerabilities that are easy to exploit once identified

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 250566 or later

Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-25-0361

Restart Required: Yes

Instructions:

1. Download enVision version 250566 or later from official vendor sources. 2. Backup current configuration and data. 3. Install the updated version following vendor documentation. 4. Restart the enVision service or system as required.

🔧 Temporary Workarounds

Network Access Restriction

all

Limit access to enVision interface to trusted IP addresses only

Rate Limiting

all

Implement rate limiting on authentication and user enumeration endpoints

🧯 If You Can't Patch

  • Implement network segmentation to isolate enVision from untrusted networks
  • Deploy web application firewall (WAF) with rules to detect and block user enumeration patterns

🔍 How to Verify

Check if Vulnerable:

Check enVision version via admin interface or system information. If version is below 250566, system is vulnerable.

Check Version:

Check via enVision web interface or consult vendor documentation for version checking

Verify Fix Applied:

Confirm version is 250566 or higher and test that user enumeration via observable discrepancies is no longer possible.

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed authentication attempts for different usernames
  • Unusual patterns of user enumeration requests
  • Access to user information endpoints from unauthorized sources

Network Indicators:

  • High volume of requests to user-related endpoints
  • Patterns suggesting automated user enumeration

SIEM Query:

source="enVision" AND (event_type="auth_failure" OR url_path CONTAINS "/user/") | stats count by src_ip, username
