Introduction
The Campcodes Online Food Ordering System V1.0 has been found to contain a critical SQL injection vulnerability in the /routers/add-item.php file. This vulnerability allows attackers to inject malicious SQL queries, gaining unauthorized access to databases, modifying or deleting data, and accessing sensitive information. In this article, we will delve into the details of this vulnerability, its impact, and provide suggested repairs to ensure system security and protect data integrity.
Affected Product
Vendor Homepage
The affected product is the Campcodes Online Food Ordering System, which can be downloaded from the vendor's homepage at https://www.campcodes.com/downloads/online-food-ordering-system-using-php-mysqli/.
Affected and/or Fixed Versions
The affected version of the product is V1.0, specifically the /routers/add-item.php file.
Submitter
The vulnerability was discovered by TEhS.
Vulnerability Details
Vulnerability Type
The vulnerability is a SQL injection vulnerability.
Root Cause
The root cause of this issue is that attackers can inject malicious code from the parameter 'price' and use it directly in SQL queries without the need for appropriate cleaning or validation. This allows attackers to forge input values, thereby manipulating SQL queries and performing unauthorized operations.
Impact
The impact of this vulnerability is severe, as attackers can exploit it to achieve unauthorized database access, sensitive data leakage, data tampering, comprehensive system control, and even service interruption. This poses a serious threat to system security and business continuity.
Description
During the security review of the "Online Food Ordering System", I discovered a critical SQL injection vulnerability in the "/routers/add-item.php" file. This vulnerability stems from insufficient user input validation of the 'price' parameter, allowing attackers to inject malicious SQL queries. Therefore, attackers can gain unauthorized access to databases, modify or delete data, and access sensitive information. Immediate remedial measures are needed to ensure system security and protect data integrity.
No Login or Authorization Required
No login or authorization is required to exploit this vulnerability.
Vulnerability Details and POC
Vulnerability Location
The vulnerability is located in the 'price' parameter.
Payload
The following payload can be used to exploit the vulnerability:
Parameter: price (POST)
Type: time-based blind
Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)
Payload: name=asdasdsa&price=123 AND (SELECT 8240 FROM (SELECT(SLEEP(5)))fVSt)&action=
Screenshots of Specific Information Obtained from Testing and Running with the sqlmap Tool
The following screenshots show some specific information obtained from testing and running with the sqlmap tool:
sqlmap -u "http://172.20.10.2/foodordering/add-item.php" -data="name=asdasdsa&price=123&action --dbs
Suggested Repair
To remediate this vulnerability, the following steps can be taken:
1. Use Prepared Statements and Parameter Binding
Preparing statements can prevent SQL injection as they separate SQL code from user input data. When using prepare statements, the value entered by the user is treated as pure data and will not be interpreted as SQL code.
2. Input Validation and Filtering
Strictly validate and filter user input data to ensure it conforms to the expected format.
3. Minimize Database User Permissions
Ensure that the account used to connect to the database has the minimum necessary permissions. Avoid using accounts with advanced permissions (such as 'root' or 'admin') for daily operations.
4. Regular Security Audits
Regularly conduct code and system security audits to promptly identify and fix potential security vulnerabilities.
Introduction
In our previous article, we discussed the critical SQL injection vulnerability found in the Campcodes Online Food Ordering System V1.0, specifically in the /routers/add-item.php file. In this article, we will provide a Q&A section to address some of the frequently asked questions related to this vulnerability.
Q&A
Q: What is a SQL injection vulnerability?
A: A SQL injection vulnerability is a type of web application security vulnerability that allows an attacker to inject malicious SQL code into a web application's database. This can be used to extract sensitive data, modify database records, or even take control of the entire database.
Q: How does the SQL injection vulnerability in the Campcodes Online Food Ordering System V1.0 work?
A: The vulnerability is located in the 'price' parameter of the /routers/add-item.php file. Attackers can inject malicious SQL code into this parameter, which is then executed by the database. This allows attackers to gain unauthorized access to databases, modify or delete data, and access sensitive information.
Q: What are the potential consequences of exploiting this vulnerability?
A: The potential consequences of exploiting this vulnerability are severe, including unauthorized database access, sensitive data leakage, data tampering, comprehensive system control, and even service interruption. This poses a serious threat to system security and business continuity.
Q: Is there a patch available to fix this vulnerability?
A: No, there is no patch available to fix this vulnerability in the Campcodes Online Food Ordering System V1.0. However, we have provided suggested repairs in our previous article, which include using prepared statements and parameter binding, input validation and filtering, minimizing database user permissions, and regular security audits.
Q: Can I prevent this vulnerability from being exploited?
A: Yes, you can prevent this vulnerability from being exploited by following the suggested repairs we provided in our previous article. Additionally, you can also take steps to prevent SQL injection attacks, such as using parameterized queries, validating user input, and limiting database privileges.
Q: How can I report a vulnerability like this?
A: If you discover a vulnerability like this, you can report it to the vendor or the developer of the affected product. You can also report it to a security researcher or a bug bounty program. It's essential to report vulnerabilities responsibly and follow the guidelines set by the vendor or the developer.
Q: What are some best practices for preventing SQL injection attacks?
A: Some best practices for preventing SQL injection attacks include:
- Using parameterized queries
- Validating user input
- Limiting database privileges
- Regularly updating and patching software
- Conducting regular security audits
- Implementing a web application firewall (WAF)
- Using a secure coding framework
By following these best practices and suggested repairs, you can help prevent SQL injection attacks and ensure the security of your system.
Conclusion
In conclusion, the SQL injection vulnerability found in the Campcodes Online Food Ordering System V1.0 is a critical issue that requires immediate attention.
