🔧 Temporary Workarounds
Block Vulnerable Endpoint
allUse web application firewall or reverse proxy to block access to /doscall/weixin/open/amr2mp3
# Example nginx location block:
location /doscall/weixin/open/amr2mp3 { deny all; }
# Example Apache .htaccess:
<Location "/doscall/weixin/open/amr2mp3">
Order deny,allow
Deny from all
</Location>
Network Segmentation
linuxIsolate Aishida system from internet and restrict access to necessary internal networks only
# Firewall rules to restrict access
# Example iptables:
iptables -A INPUT -p tcp --dport [AISHIDA_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [AISHIDA_PORT] -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the vulnerable system from critical infrastructure
- Deploy web application firewall with specific rules to detect and block command injection attempts
🔍 How to Verify
Check if Vulnerable:
Check if system is running Aishida Call Center System version 20250314 or earlier and has the /doscall/weixin/open/amr2mp3 endpoint accessibleCheck Version:
Check system documentation, configuration files, or contact vendor for version informationVerify Fix Applied:
Test if the /doscall/weixin/open/amr2mp3 endpoint is no longer accessible or properly sanitizes input📡 Detection & Monitoring
