CVE-2017-17777
📋 TL;DR
CVE-2017-17777 is an authentication bypass vulnerability in Paid To Read Script 2.0.5 that allows unauthenticated attackers to access admin panel functions. Attackers can directly request admin pages with specific parameters to bypass authentication checks. This affects all installations of Paid To Read Script 2.0.5 that expose the admin panel.
💻 Affected Systems

📦 What is this software?
Paid To Read Script by Paid To Read Script Project
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the admin panel allowing attackers to view sensitive user data, modify system settings, and potentially execute arbitrary code through other vulnerabilities.
Likely Case
Unauthorized access to user data and administrative functions, potentially leading to data theft, privilege escalation, or system manipulation.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to admin interfaces.
🎯 Exploit Status
Exploitation requires only HTTP requests to specific URLs with parameters. No authentication or special tools needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Implement proper authentication checks
allAdd authentication verification to admin/viewvisitcamp.php and admin/userview.php files before processing requests.
Edit PHP files to include session validation: if(!isset($_SESSION['admin_logged_in']) || $_SESSION['admin_logged_in'] !== true) { header('Location: login.php'); exit(); }
Restrict admin panel access
allUse web server configuration to restrict access to admin directory to specific IP addresses.
For Apache: .htaccess with 'Require ip 192.168.1.0/24'
For Nginx: location /admin { allow 192.168.1.0/24; deny all; }
🧯 If You Can't Patch
- Move admin panel to internal network only with firewall rules blocking external access
- Implement web application firewall (WAF) rules to block direct requests to vulnerable endpoints
🔍 How to Verify
Check if Vulnerable:
Attempt to access http://[target]/admin/viewvisitcamp.php?fn=test or http://[target]/admin/userview.php?uid=1 without authentication. If data is returned, system is vulnerable.
Check Version:
Check script version in admin panel or readme files. Look for 'Paid To Read Script 2.0.5' in source code.
Verify Fix Applied:
After implementing fixes, repeat the vulnerable check. Should receive authentication prompt or redirect to login page.
📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /admin/viewvisitcamp.php or /admin/userview.php without preceding authentication requests
- Multiple failed login attempts followed by direct admin access
Network Indicators:
- Unusual traffic patterns to admin endpoints from unauthorized IPs
- Direct parameterized requests to admin URLs
SIEM Query:
source="web_logs" AND (url="/admin/viewvisitcamp.php" OR url="/admin/userview.php") AND NOT (referer="*/login.php" OR user_agent="*bot*")
