CVE-2025-5403
📋 TL;DR
This critical SQL injection vulnerability in Blogbook's admin interface allows attackers to manipulate database queries via the post_id parameter in /admin/view_all_posts.php. Remote attackers can potentially read, modify, or delete database content. All installations up to commit 92f5cf90f8a7e6566b576fe0952e14e1c6736513 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, privilege escalation to admin, and potential server takeover via SQL injection chaining.
Likely Case
Unauthorized access to sensitive blog data (posts, user information), data manipulation, and potential authentication bypass.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or partial data exposure.
🎯 Exploit Status
Exploit requires admin access to reach /admin/view_all_posts.php. Public proof-of-concept exists in GitHub repository.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None
Restart Required: No
Instructions:
No official patch available. Vendor has not responded to disclosure. Consider migrating to alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify /admin/view_all_posts.php to implement proper input validation and use parameterized queries for the post_id parameter.
Edit the PHP file to replace direct SQL concatenation with prepared statements using PDO or mysqli
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the post_id parameter.
Add WAF rule: Detect and block SQL injection patterns in GET parameters, specifically targeting post_id
🧯 If You Can't Patch
- Restrict access to /admin/ directory to specific IP addresses only
- Implement database user with minimal permissions (read-only if possible) for the application
🔍 How to Verify
Check if Vulnerable:
Test the /admin/view_all_posts.php endpoint with SQL injection payloads in the post_id parameter (e.g., post_id=1' OR '1'='1). Check for database errors or unexpected behavior.Check Version:
Check Git commit hash: git log --oneline -1Verify Fix Applied:
After implementing parameterized queries, test with the same SQL injection payloads and verify they no longer execute or cause errors.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed parameter validation attempts on /admin/view_all_posts.php
- Suspicious GET parameters containing SQL keywords
Network Indicators:
- HTTP requests to /admin/view_all_posts.php with SQL injection patterns in parameters
- Unusual database query patterns from web server IP
SIEM Query:
source="web_logs" AND uri_path="/admin/view_all_posts.php" AND (query_string="*post_id=*'*" OR query_string="*post_id=*%27*" OR query_string="*post_id=*SELECT*" OR query_string="*post_id=*UNION*")
