CVE-2025-12001
📋 TL;DR
This vulnerability allows attackers to inject malicious scripts into application manifests, which could lead to stored cross-site scripting (XSS) attacks when other users view the affected manifests. It affects BLU-IC2 and BLU-IC4 products up to version 1.19.5. Users of these products who view or interact with manipulated manifests are at risk.
💻 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
Attackers could execute arbitrary JavaScript in victims' browsers, potentially stealing session cookies, performing actions on behalf of users, or redirecting to malicious sites.
Likely Case
Attackers with access to modify manifests could inject scripts that steal user data or perform limited malicious actions within the application context.
If Mitigated
With proper input validation and output encoding, malicious scripts would be rendered harmless as text rather than executable code.
🎯 Exploit Status
Exploitation requires ability to modify application manifests and for victims to view the manipulated manifests.
🛠️ 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 product's version command. 2. If version is 1.19.5 or earlier, upgrade to the latest version. 3. Verify the fix by checking that manifest inputs are properly sanitized.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize manifest content before storage
Implement input validation for all manifest fields to strip or encode script tags and JavaScript
Output Encoding
allApply proper output encoding when displaying manifest content to users
Use HTML entity encoding for all user-controlled content displayed in web interfaces
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in manifest data
- Restrict access to manifest modification functionality to trusted users only
🔍 How to Verify
Check if Vulnerable:
Check if your BLU-IC2/BLU-IC4 version is 1.19.5 or earlier using the product's version commandCheck Version:
Use product-specific command to check version (consult product documentation)Verify Fix Applied:
After patching, test manifest fields with XSS payloads to ensure they are properly sanitized and not executed📡 Detection & Monitoring
Log Indicators:
- Unusual manifest modifications
- Multiple failed manifest validation attempts
- Suspicious characters in manifest content logs
Network Indicators:
- Unexpected script tags in manifest-related API calls
- Suspicious JavaScript in HTTP POST/PUT requests to manifest endpoints
SIEM Query:
search 'manifest' AND ('script' OR 'javascript' OR 'onload' OR 'onerror') in web request logs
