CVE-2023-31822
📋 TL;DR
This vulnerability in Entetsu Store v.13.4.1 allows remote attackers to access sensitive information through the channel access token in the miniapp function. It affects systems running this specific version of Entetsu Store software. Attackers can exploit this without authentication to potentially steal confidential data.
💻 Affected Systems
- Entetsu Store
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of sensitive user data, financial information, or authentication credentials leading to account takeover and data breaches.
Likely Case
Unauthorized access to sensitive information stored in the miniapp function, potentially exposing user data or system configuration details.
If Mitigated
Limited or no data exposure if proper access controls and token validation are implemented.
🎯 Exploit Status
References indicate public proof-of-concept exists, and exploitation appears straightforward based on the CWE-311 (Missing Encryption of Sensitive Data) classification.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: http://entetsu.com
Restart Required: No
Instructions:
1. Check vendor website for updates
2. Apply any available patches
3. Verify the fix by testing the miniapp function
🔧 Temporary Workarounds
Disable miniapp function
allTemporarily disable the vulnerable miniapp Entetsu Store function until patched
Specific commands depend on Entetsu Store configuration
Implement network restrictions
allRestrict access to the Entetsu Store service to trusted networks only
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_NETWORK" port port="PORT" protocol="tcp" accept'
netsh advfirewall firewall add rule name="Restrict Entetsu" dir=in action=allow remoteip=TRUSTED_NETWORK localport=PORT protocol=TCP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Entetsu Store systems
- Deploy web application firewall (WAF) rules to detect and block suspicious token access patterns
🔍 How to Verify
Check if Vulnerable:
Check if running Entetsu Store v.13.4.1 and test if channel access tokens can be accessed without proper authorizationCheck Version:
Check Entetsu Store configuration or admin interface for version informationVerify Fix Applied:
Test the miniapp function to ensure channel access tokens are properly encrypted and access-controlled📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to channel access token endpoints
- Multiple failed token validation attempts
- Access from unexpected IP addresses to miniapp functions
Network Indicators:
- Unencrypted transmission of access tokens
- Excessive requests to token-related endpoints
- Traffic patterns suggesting token enumeration
SIEM Query:
