CVE-2018-10735 Scanner

NagiosXI is used widely in IT infrastructure monitoring by organizations to ensure their systems and applications are functioning properly. Network administrators and IT professionals use it to monitor various metrics and alert them of any issues promptly. By being highly customizable, NagiosXI facilitates adapting to diverse network environments. This application offers comprehensive dashboards, allowing real-time observation of network health and performance. It is also favored for its ability to integrate seamlessly with other systems and third-party plugins to enhance monitoring capabilities further. As crucial software in maintaining IT infrastructure, consistent updates ensure NagiosXI addresses evolving security and performance needs.

SQL Injection vulnerabilities in web applications like NagiosXI can lead to serious security breaches. This vulnerability occurs when an attacker can execute arbitrary SQL code within an application's database. In such scenarios, the attacker might exploit the database backend processing user requests to access unauthorized data. SQL Injection attacks typically target data confidentiality and integrity, causing unauthorized data exposure or alteration. With NagiosXI, such vulnerabilities could permit attackers to manipulate data controlling the monitoring systems. It’s crucial for admins to address such vulnerabilities to protect critical infrastructure data and ensure system reliability.

The SQL Injection vulnerability found in NagiosXI manifests in the admin/commandline.php script through the 'cname' parameter. This endpoint, which processes administrative commands, fails to properly sanitize user inputs, making it susceptible to SQL Injection. Attackers can exploit this by injecting malicious SQL code that might bypass authentication or manipulate database commands. Successful exploitation requires crafting specific inputs to match the SQL query structure. The template checks for this vulnerability by detecting SQL injection patterns that create echoes of predictable outcomes, such as checking for MD5 hash outputs within response bodies. Such testing helps confirm the presence of unsanitized, executable SQL commands in NagiosXI’s parameter handling.

When exploited, this SQL Injection could have significant consequences, including unauthorized data retrieval from the database. Besides data exposure, attackers might inject additional malicious payloads capable of modifying or deleting content within the monitored environments. This disruption could hinder the integrity of the NagiosXI monitoring outputs or system, distorting alerts and causing operational misalignments. Furthermore, extensive exploitation might allow the alteration of critical database configurations used by NagiosXI to monitor and alert on system activities, reducing the organizational control over IT monitoring landscapes.
