CVE-2024-31842
📋 TL;DR
This vulnerability in Italtel Embrace 1.6.4 exposes user access tokens in URL query strings via GET requests, allowing attackers to steal session credentials. Attackers can use stolen tokens to impersonate authenticated users and potentially take over accounts. All deployments of Italtel Embrace 1.6.4 are affected.

📦 What is this software?
Embrace by Italtel
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover leading to unauthorized access to sensitive data, privilege escalation, and potential lateral movement within the system.
Likely Case
Session hijacking allowing attackers to access authenticated user sessions and perform actions as legitimate users.
If Mitigated
Limited impact if tokens have short expiration times, proper logging/monitoring exists, and network segmentation limits exposure.
🎯 Exploit Status
Exploitation requires obtaining the access token through logs, browser history, or referrer headers, but token usage is straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.gruppotim.it/it/footer/red-team.html
Restart Required: No
Instructions:
Check vendor advisory for patch availability. If patched, update to fixed version and verify access tokens are no longer transmitted via GET requests.
🔧 Temporary Workarounds
Configure web server to strip sensitive headers
allConfigure reverse proxies or web servers to strip Referer headers containing sensitive URLs
# Apache: Header edit Referer "^https?://[^/]+/.*token=.*" "REDACTED"
# Nginx: proxy_hide_header Referer;
Implement short session timeouts
allReduce access token validity period to limit exposure window
# Application configuration setting - consult Italtel Embrace documentation
🧯 If You Can't Patch
- Implement network segmentation to isolate Italtel Embrace from untrusted networks
- Deploy WAF rules to block requests containing access tokens in URLs
🔍 How to Verify
Check if Vulnerable:
Monitor network traffic or browser developer tools to check if access tokens appear in GET request URLs or query parameters.Check Version:
Check Italtel Embrace administration interface or configuration files for version informationVerify Fix Applied:
Verify that access tokens are no longer transmitted in URL query strings and are instead sent via POST requests or secure headers.📡 Detection & Monitoring
Log Indicators:
- GET requests containing 'token=' parameters in URLs
- Multiple failed authentication attempts followed by successful access with stolen token
Network Indicators:
- Unusual access patterns from new IP addresses using valid tokens
- Tokens appearing in Referer headers to external sites
SIEM Query:
