⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain full PHP configuration, environment variables, database credentials, and system paths, enabling further attacks like credential theft, privilege escalation, or targeted exploitation.
Likely Case
Attackers gather system information including PHP settings, installed extensions, server paths, and potentially sensitive configuration details that could aid in reconnaissance for additional attacks.
If Mitigated
Limited information disclosure with no direct system compromise, though it still provides attackers with valuable reconnaissance data.

Patch Version: Unknown
Vendor Advisory: https://github.com/rainrocka/xinhu/issues/11
Restart Required: No
Instructions:
1. Monitor the GitHub repository for patches. 2. Apply any available updates. 3. Remove or restrict access to phpinfo() functionality.
🔧 Temporary Workarounds
Restrict access to index.php with vulnerable parameter
allImplement web server rules to block requests containing the vulnerable 'a' parameter pattern
# For Apache: RewriteEngine On
RewriteCond %{QUERY_STRING} a=phpinfo [NC]
RewriteRule ^index\.php$ - [F,L]
# For Nginx: location ~* ^/index\.php$ { if ($arg_a ~* phpinfo) { return 403; } }
Disable phpinfo function
allPrevent phpinfo() from executing via PHP configuration
# Add to php.ini: disable_functions = phpinfo
🧯 If You Can't Patch
- Implement strict input validation for the 'a' parameter in index.php
- Deploy WAF rules to block requests attempting to access phpinfo()
🔍 How to Verify
Check if Vulnerable:
Access http://[target]/index.php?a=phpinfo and check if phpinfo output appearsCheck Version:
Check RockOA version in admin panel or configuration filesVerify Fix Applied:
Attempt the same request and verify phpinfo output is blocked or returns error📡 Detection & Monitoring
