CVE-2025-26047
📋 TL;DR
Loggrove v1.0 contains a SQL injection vulnerability in the read.py file that allows attackers to execute arbitrary SQL commands. This affects all users running Loggrove v1.0 with the vulnerable component enabled. Attackers could potentially read, modify, or delete database information.

📦 What is this software?
Loggrove by Olajowon
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, or unauthorized administrative access to the underlying system.
Likely Case
Unauthorized data extraction from the database, potentially exposing sensitive log information or user data.
If Mitigated
Limited impact with proper input validation and database permissions restricting the attack surface.
🎯 Exploit Status
SQL injection vulnerabilities typically have low exploitation complexity when unauthenticated access is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://gitee.com/olajowon/loggrove/issues/IBJXG8
Restart Required: Yes
Instructions:
1. Monitor the Gitee repository for patches. 2. Apply any available security updates. 3. Restart the Loggrove service after patching.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement proper input validation and parameterized queries in the read.py file to prevent SQL injection.
# Review and modify read.py to use parameterized queries instead of string concatenation
Network Access Control
linuxRestrict network access to the Loggrove service to only trusted sources.
# Example firewall rule: iptables -A INPUT -p tcp --dport [LOGGROVE_PORT] -s [TRUSTED_IP] -j ACCEPT
# iptables -A INPUT -p tcp --dport [LOGGROVE_PORT] -j DROP
🧯 If You Can't Patch
- Implement a web application firewall (WAF) with SQL injection detection rules
- Restrict database user permissions to minimum required privileges
🔍 How to Verify
Check if Vulnerable:
Review the read.py file for SQL query construction without proper parameterization or input validation.Check Version:
# Check Loggrove version if available in configuration or via package managerVerify Fix Applied:
Test the vulnerable endpoint with SQL injection payloads to confirm they are properly blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts with SQL-like patterns
- Unexpected database queries from the Loggrove application
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) to the Loggrove endpoint
- Unusual traffic patterns to database ports from the Loggrove server
SIEM Query:
source="loggrove.log" AND ("SQL" OR "syntax" OR "union" OR "select")
