CVE-2025-13582: Jonnys Liquor SQL Injection Vulnerability

CVE-2025-13582 Overview

A SQL injection vulnerability has been discovered in code-projects Jonnys Liquor version 1.0. This security flaw exists within the /detail.php file of the application's GET Parameter Handler component. An attacker can exploit this vulnerability by manipulating the Product argument, allowing for SQL injection attacks. The vulnerability is remotely exploitable, and exploit details have been publicly released, increasing the risk of active exploitation.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to potentially access, modify, or delete database contents, extract sensitive information, or execute administrative operations on the underlying database system.

Affected Products

• Anisha Jonnys Liquor 1.0

Technical Details for CVE-2025-13582

Vulnerability Analysis

This vulnerability represents a classic SQL injection flaw (CWE-89) in a web application's parameter handling logic. The /detail.php endpoint accepts a Product parameter via GET requests but fails to properly sanitize or validate user-supplied input before incorporating it into SQL queries. This improper neutralization of special elements (CWE-74) enables attackers to inject malicious SQL statements that will be executed by the backend database.

The vulnerability requires no authentication and can be exploited remotely over the network with low attack complexity. An attacker does not need any special privileges or user interaction to successfully exploit this flaw, making it accessible to opportunistic attackers.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries in the /detail.php file. When the application processes the Product GET parameter, it directly concatenates user input into SQL query strings without proper sanitization or escaping. This allows special characters and SQL syntax to be interpreted as part of the query rather than as literal data values.

Attack Vector

The attack is network-based, allowing remote exploitation without authentication. An attacker can craft a malicious URL containing SQL injection payloads in the Product parameter. When the application processes this request, the injected SQL code is executed against the database, potentially allowing the attacker to:

• Extract sensitive data from the database
• Modify or delete existing records
• Bypass authentication mechanisms
• Potentially achieve command execution on the underlying system depending on database configuration

The vulnerability is exploited by sending specially crafted GET requests to the /detail.php endpoint with malicious SQL syntax embedded in the Product parameter value. Common techniques include union-based injection, boolean-based blind injection, and time-based blind injection to extract database contents.

Detection Methods for CVE-2025-13582

Indicators of Compromise

• HTTP requests to /detail.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences (--, /**/) in the Product parameter
• Web server access logs showing unusual or malformed Product parameter values with encoded special characters (%27, %22, %3B)
• Database error messages appearing in application responses or logs indicating SQL syntax errors
• Unexpected database query patterns or elevated database activity from the web application

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in GET parameters
• Implement application-layer logging to capture and analyze all requests to /detail.php
• Configure database audit logging to track anomalous query patterns
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor web server logs for requests to /detail.php with suspicious parameter values
• Set up alerts for database errors or unusual query execution times that may indicate injection attempts
• Review application logs for repeated failed requests that could indicate automated exploitation attempts
• Implement real-time monitoring for data exfiltration patterns from the database server

How to Mitigate CVE-2025-13582

Immediate Actions Required

• Remove or disable public access to the Jonnys Liquor application until a patch is applied
• Implement WAF rules to block requests containing SQL injection patterns targeting the Product parameter
• Review database logs for signs of prior exploitation and conduct forensic analysis if compromise is suspected
• Consider network segmentation to limit database access from the web application server

Patch Information

As of the last update on December 02, 2025, no official vendor patch has been released for this vulnerability. Organizations using Jonnys Liquor 1.0 should monitor the Code Projects Resource for security updates. Additional vulnerability details can be found in the GitHub Issue #5 and VulDB #333346.

Workarounds

• Implement input validation to reject requests containing SQL special characters in the Product parameter
• Deploy a reverse proxy or WAF with SQL injection blocking capabilities in front of the application
• Restrict database user permissions to minimize the impact of successful SQL injection attacks
• If source code access is available, modify /detail.php to use parameterized queries or prepared statements
