Campcodes Online Traffic Offense Management System 1. has been found to have a critical SQL injection vulnerability. This vulnerability, assigned identifier VDB-226051, affects an unknown functionality of the /classes/Login.php file. The manipulation of the 'password' argument leads to this SQL injection, which can be remotely exploited. The exploit details have been publicly disclosed, putting numerous installations at potential risk.

Understanding the vulnerability

In simple terms, an SQL injection occurs when an attacker is able to manipulate an application's SQL query, allowing them to execute arbitrary queries on the database, potentially leading to unauthorized data access, modification, or even deletion. In the case of CVE-2023-2073, the vulnerability lies in the /classes/Login.php file, where user's passwords are not properly sanitized, allowing for potential exploitation.

Let us examine a sample code snippet from the vulnerable file /classes/Login.php

function login($uname, $password) {
  $sql = "SELECT * FROM users WHERE username='$uname' AND password='$password'";
  //...
}

In this example, the $uname and $password variables are directly inserted into the SQL query without proper sanitization, making it vulnerable to an SQL injection attack. Here, an attacker could input a specially crafted password, like ' OR '1'='1, manipulating the SQL query.

For instance, an attacker could use the following input

username: admin
password: ' OR '1'='1

This would result in the following SQL query

SELECT * FROM users WHERE username='admin' AND password='' OR '1'='1'

Due to the manipulated query, an attacker would successfully gain access as 'admin' without knowing the actual password.

Mitigation strategies

In order to protect against this particular SQL injection, it is recommended to sanitize all user inputs before inserting them into SQL queries. One possible solution would be utilizing prepared statements, which prevent user inputs from being treated as executable SQL code.

Here's an example of a more secure implementation of the login function with prepared statements

function login($uname, $password) {
  $sql = "SELECT * FROM users WHERE username=? AND password=?";
  $stmt = $this->conn->prepare($sql);
  $stmt->bind_param("ss", $uname, $password);
  $stmt->execute();
  // ...
}

In conclusion, the CVE-2023-2073 vulnerability poses a critical risk to installations of Campcodes Online Traffic Offense Management System 1.. With the exploit details publicly disclosed, it's urgent for affected parties to apply appropriate mitigation strategies and update to a secure version of the software.
