🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates or consider workarounds.
🔧 Temporary Workarounds
Disable rememberMe functionality
allTemporarily disable the rememberMe cookie functionality that triggers the vulnerable deserialization
Modify /application/common.php to remove or comment out rememberMe cookie handling
Input validation filter
allAdd input validation to sanitize cookie data before deserialization
Add input sanitization in checkUserCookie function before unserialize() calls
🧯 If You Can't Patch
- Implement WAF rules to block suspicious deserialization patterns in HTTP requests
- Restrict network access to Aidigu application using firewall rules
🔍 How to Verify
Check if Vulnerable:
Check if Aidigu version is 1.8.2 or earlier and if /application/common.php contains vulnerable checkUserCookie function
Check Version:
Check application configuration files or vendor documentation for version information
Verify Fix Applied:
Verify that rememberMe cookie handling has been modified or disabled in the code
📡 Detection & Monitoring
Log Indicators:
- Unusual rememberMe cookie values in access logs
- Multiple failed authentication attempts with crafted cookies
Network Indicators:
- HTTP requests with unusually long or encoded rememberMe cookie parameters
SIEM Query:
source="web_logs" AND (cookie="*rememberMe*" AND (cookie_length>500 OR cookie CONTAINS "O:"))
