CVE-2025-12031
📋 TL;DR
This vulnerability allows attackers to read sensitive cookies via JavaScript due to missing Secure and HttpOnly attributes. It affects BLU-IC2 and BLU-IC4 devices up to version 1.19.5, potentially exposing session tokens and authentication credentials.
💻 Affected Systems
- BLU-IC2
- BLU-IC4
📦 What is this software?
Blu Ic2 Firmware by Azure Access
Blu Ic4 Firmware by Azure Access
⚠️ Risk & Real-World Impact
Worst Case
Full session hijacking leading to unauthorized access, data theft, and privilege escalation within affected systems.
Likely Case
Session token theft enabling unauthorized access to user accounts and sensitive functionality.
If Mitigated
Minimal impact as cookies remain protected from JavaScript access and transmission only over HTTPS.
🎯 Exploit Status
Requires ability to execute JavaScript in victim's browser context (typically via XSS). No authentication bypass needed once JavaScript execution is achieved.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after 1.19.5
Vendor Advisory: https://azure-access.com/security-advisories
Restart Required: No
Instructions:
1. Check current version using device management interface. 2. Download and apply firmware update beyond version 1.19.5. 3. Verify cookie attributes are properly set after update.
🔧 Temporary Workarounds
Manual Cookie Attribute Configuration
allManually configure all sensitive cookies with Secure and HttpOnly flags in application configuration
Specific commands depend on application framework - configure Set-Cookie headers with 'Secure; HttpOnly' attributes
🧯 If You Can't Patch
- Implement WAF rules to add Secure and HttpOnly attributes to Set-Cookie headers
- Use Content Security Policy (CSP) to restrict script execution and mitigate XSS vectors
🔍 How to Verify
Check if Vulnerable:
Inspect browser developer tools (Application tab) to check if sensitive cookies lack Secure and HttpOnly flagsCheck Version:
Check device web interface or use vendor-specific CLI commands to display firmware versionVerify Fix Applied:
Verify cookies show 'Secure' and 'HttpOnly' attributes in browser developer tools and are only sent over HTTPS📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts from same session
- Unusual cookie access patterns in application logs
Network Indicators:
- Cookies transmitted over HTTP instead of HTTPS
- JavaScript attempting to access document.cookie with sensitive values
SIEM Query:
source="web_server" AND (cookie_access="document.cookie" OR protocol="HTTP" AND cookie_present="true")
