CVE-2018-10738 Scanner

Nagios XI is a popular IT infrastructure monitoring tool used by organizations to monitor system performance, detect failures, and ensure the smooth running of IT environments. It is typically used by IT departments in various sectors, including finance, healthcare, and telecommunications, due to its robust monitoring capabilities and scalability. As an enterprise-grade solution, it allows users to monitor network devices, host performance, and application services through both on-premises and cloud installations. The software supports various monitoring features, alerting mechanisms, and integration options, making it a go-to choice for complex IT landscapes. Nagios XI is appreciated for its extendability, which helps in customizing monitoring according to specific needs. Due to its comprehensive nature, keeping it up to date is crucial to safeguarding against vulnerabilities.

SQL Injection vulnerabilities occur when an attacker can interfere with the queries an application makes to its database by inserting or manipulating SQL commands. This specific vulnerability in Nagios XI, prior to version 5.4.13, arises in the admin/menuaccess.php page and involves the misuse of the chbKey1 parameter. SQL Injection attacks can potentially lead to unauthorized viewing of data, modification of data, or even full control of the database server. Attackers often exploit such vulnerabilities to extract sensitive information without the need for authorization. This can lead to further security breaches if not patched promptly. Proper input sanitization and parameterized queries are vital in preventing SQL Injection attacks.

The technical details of this vulnerability involve an issue in the handling of the chbKey1 parameter in the menuaccess.php file, which is not properly sanitized. This allows attackers to inject arbitrary SQL commands into the database through crafted HTTP POST requests. The vulnerability is exploited by manipulating the chbKey1 parameter to include SQL code that results in unauthorized data extraction or modification. The use of the MD5 function within the queries suggests attempts to bypass conventional checks and balance mechanisms. By exploiting such vulnerabilities, attackers can access sensitive data like user credentials or exploit other weaknesses in the system infrastructure.

Exploiting this SQL Injection vulnerability can have severe consequences, including unauthorized access to sensitive information stored in the application's database. Attackers could potentially modify, delete, or leak confidential data, leading to data breaches, loss of integrity, and loss of customer trust. It might also allow an attacker to execute arbitrary commands on the server, leading to further compromises and potential spread to other parts of the network. Such vulnerabilities can disrupt normal business operations and result in significant financial and reputational damage. Therefore, mitigating these vulnerabilities is crucial for the security posture of an organization.
