The vulnerability CVE-2019-19486 represents a critical local file inclusion flaw in the Centreon monitoring platform version 19.04.4 and earlier. This security weakness exists within the minPlayCommand.php script which is part of the web interface used for managing monitoring commands and plugins. The vulnerability stems from insufficient input validation and sanitization mechanisms that fail to properly filter user-supplied parameters before processing them in file operations. Attackers can exploit this flaw by crafting malicious input that triggers directory traversal sequences, allowing them to access arbitrary files on the server filesystem. The vulnerability specifically manifests when the application processes plugin test functionality, where user-controllable data is directly incorporated into file path operations without adequate security controls.
The technical exploitation of this vulnerability follows a classic local file inclusion pattern where an attacker manipulates the input parameters to bypass normal file access restrictions. When the minPlayCommand.php script processes plugin test requests, it accepts user-provided data that should be validated and sanitized before being used in file system operations. The lack of proper input validation creates an opportunity for attackers to inject malicious path traversal sequences such as ../ or ../../../ which can navigate to sensitive files outside the intended directory structure. This flaw enables attackers to potentially read configuration files, database credentials, application source code, or other sensitive system information that should remain protected. The vulnerability operates at the application layer and can be exploited through web-based interfaces without requiring special privileges or authentication.
The operational impact of CVE-2019-19486 extends beyond simple information disclosure, as it can lead to complete system compromise when combined with other attack vectors. An attacker who successfully exploits this vulnerability can gain access to sensitive system information including database connection details, administrative credentials, and application configuration files that may contain encryption keys or other critical security parameters. The exposure of these files can facilitate further attacks such as privilege escalation, database compromise, or lateral movement within the network infrastructure. Additionally, the ability to read arbitrary files may enable attackers to discover other vulnerabilities or system weaknesses that can be exploited to gain deeper access to the compromised system. The vulnerability affects the integrity and confidentiality of the Centreon monitoring platform, potentially compromising the security of the entire monitoring infrastructure that relies on this system.
Organizations affected by this vulnerability should implement immediate mitigations including upgrading to Centreon version 19.10.0 or later where this vulnerability has been addressed through proper input validation and sanitization. The fix typically involves implementing strict input validation controls that reject or sanitize any path traversal sequences before processing user-supplied data. Security teams should also consider implementing web application firewalls with rules specifically designed to detect and block directory traversal attempts, as well as conducting thorough code reviews to identify similar vulnerabilities in other components of the monitoring platform. The vulnerability aligns with CWE-22 which describes improper limitation of a pathname to a restricted directory, and represents a common attack pattern that appears in the MITRE ATT&CK framework under the technique of directory traversal. Organizations should also perform comprehensive security assessments of their monitoring infrastructure to identify potential additional vulnerabilities that may have similar attack surfaces and exploitation patterns.
