CVE Report - Phpgurukul Boat Booking System-PHP V1.0 SQL injection in /boat-details.php

SQL injection Vulnerability in Phpgurukul Boat Booking System-PHP V1.0

Vulnerability Description

SQL injection is a code injection technique used to attack data-driven applications by inserting malicious SQL statements into an entry field for execution. It exploits vulnerabilities in an application's software, such as improper filtering of user input or lack of strong typing, allowing attackers to manipulate SQL queries. This can lead to unauthorized access, data breaches, and other serious security issues.

Affected Components

The vulnerability is located in the /boat-details.php file, specifically on line 65. The vulnerable code is as follows:

$rs = $query = mysqli_query($con, "SELECT * FROM tblboat WHERE ID='$bid'");

In this code, the user input $bid is directly inserted into the SQL query without proper sanitization or validation. This allows an attacker to inject malicious SQL code and manipulate the query.

Attack Steps

There are several ways an attacker can exploit this vulnerability:

Boolean-based Blind

An attacker can use a boolean-based blind attack to extract information from the database. The following example demonstrates how to do this:

bid=1' AND 2740=2740 AND 'wrlL'='wrlL

In this example, the attacker is using a boolean-based blind attack to extract information from the database. The AND operator is used to combine two conditions, and the 2740=2740 condition is always true. The attacker is then using the AND operator to combine this condition with the wrlL='wrlL condition, which is also always true.

Time-based Blind

An attacker can use a time-based blind attack to extract information from the database. The following example demonstrates how to do this:

bid=1' AND (SELECT 1184 FROM (SELECT(SLEEP(5)))BDaU) AND 'ALMH'='ALMH

In this example, the attacker is using a time-based blind attack to extract information from the database. The SELECT(SLEEP(5)) statement is used to introduce a delay of 5 seconds, and the attacker is then using the AND operator to combine this condition with the ALMH='ALMH condition, which is always true.

UNION Query

An attacker can use a UNION query to extract information from the database. The following example demonstrates how to do this:

bid=1' UNION ALL SELECT NULL,NULL,NULL,NULL,NULL,NULL,NULL,CONCAT(0x716a7a7171,0x585044684d4e5a71486a506966564a565a686a67416a63716a6f647a53484f5349684769445a4275,0x716b627a71),NULL,NULL,NULL,NULL-- -

In this example, the attacker is using a UNION query to extract information from the database. The UNION ALL operator is used to combine the results of two queries, and the attacker is then using the CONCAT function to combine the results of the two queries.

Affected Versions

The vulnerability affects Phpgurukul Boat Booking System-PHP V1.0.

Suggested Fix

To fix this vulnerability, the code in the /boat-details.php file should be updated to properly sanitize and validate user input. This can be done by using prepared statements or parameterized queries.

Contact Information

If you have any questions or concerns about this vulnerability, please contact the reporter at 1cfh.

Recommendations

To prevent similar vulnerabilities in the future, we recommend the following:

  • Always properly sanitize and validate user input.
  • Use prepared statements or parameterized queries to prevent SQL injection attacks.
  • Regularly update and patch your software to ensure you have the latest security fixes.
  • Implement a web application firewall (WAF) to detect and prevent SQL injection attacks.
  • Conduct regular security audits and penetration testing to identify and address vulnerabilities.

$rs = $query = mysqli_query($con, "SELECT * FROM tblboat WHERE ID='$bid'");

In this code, the user input $bid is directly inserted into the SQL query without proper sanitization or validation. This allows an attacker to inject malicious SQL code and manipulate the query.

Q: What are the different types of SQL injection attacks?

A: There are several types of SQL injection attacks, including:

  • Boolean-based blind: This type of attack uses boolean logic to extract information from the database.
  • Time-based blind: This type of attack uses a delay to extract information from the database.
  • UNION query: This type of attack uses a UNION query to extract information from the database.

Q: How can an attacker exploit the SQL injection vulnerability in the Phpgurukul Boat Booking System?

A: An attacker can exploit the SQL injection vulnerability in the Phpgurukul Boat Booking System by injecting malicious SQL code into the /boat-details.php file. The attacker can use a boolean-based blind, time-based blind, or UNION query attack to extract information from the database.

Q: What are the consequences of a successful SQL injection attack on the Phpgurukul Boat Booking System?

A: A successful SQL injection attack on the Phpgurukul Boat Booking System can lead to unauthorized access, data breaches, and other serious security issues. The attacker may be able to extract sensitive information from the database, such as user credentials, credit card numbers, or other personal data.

Q: How can the Phpgurukul Boat Booking System be fixed to prevent SQL injection attacks?

A: The Phpgurukul Boat Booking System can be fixed to prevent SQL injection attacks by properly sanitizing and validating user input. This can be done by using prepared statements or parameterized queries. Additionally, the code in the /boat-details.php file should be updated to prevent SQL injection attacks.

Q: What are some best practices for preventing SQL injection attacks?

A: Some best practices for preventing SQL injection attacks include:

  • Properly sanitizing and validating user input: This can be done by using prepared statements or parameterized queries.
  • Using a web application firewall (WAF): A WAF can detect and prevent SQL injection attacks.
  • Regularly updating and patching software: Regularly updating and patching software can help prevent SQL injection attacks.
  • Conducting regular security audits and penetration testing: Regular security audits and penetration testing can help identify and address vulnerabilities.
