The vulnerability identified as CVE-2018-11588 affects Centreon version 3.4.6 and Centreon Web 2.8.23, representing a critical security flaw that enables authenticated users to execute stored cross-site scripting attacks. This vulnerability stems from insufficient input validation and sanitization within the web application's user interface components, specifically targeting the menu management and command configuration modules. The flaw allows an attacker with valid credentials to inject malicious payloads into username fields or command descriptions, which are then stored within the application's database and subsequently executed when other users view the affected content.
The technical implementation of this vulnerability occurs through the manipulation of input fields in two primary locations: www/include/core/menu/menu.php and www/include/configuration/configObject/command/formArguments.php. These files handle the rendering and processing of user-defined data within the Centreon administration interface, where proper sanitization of user inputs fails to occur. When an authenticated user submits malicious JavaScript code through these interfaces, the payload becomes permanently stored within the application's data store, making it susceptible to execution whenever the affected data is displayed to other authenticated users. This stored XSS vulnerability operates under CWE-79 which classifies it as a cross-site scripting flaw, specifically categorized as a stored XSS attack where malicious scripts are permanently stored on the target server.
The operational impact of this vulnerability extends beyond simple data theft or session hijacking, as it provides attackers with the capability to perform privilege escalation and maintain persistent access to the compromised Centreon environment. An attacker could leverage this vulnerability to inject malicious scripts that redirect users to phishing sites, steal session cookies, or even execute arbitrary commands within the context of the victim's browser. The stored nature of the vulnerability means that the malicious payload remains active even after the initial injection, potentially affecting all users who access the affected menu items or command configurations. This makes the vulnerability particularly dangerous in environments where Centreon serves as a critical monitoring platform for IT infrastructure, as it could be exploited to compromise the entire monitoring ecosystem.
Organizations utilizing Centreon 3.4.6 and Centreon Web 2.8.23 should immediately implement mitigations including input validation and sanitization measures, proper output encoding, and regular security updates. The remediation strategy should focus on implementing strict input validation rules that prevent the injection of potentially dangerous characters and script tags within user-controllable fields. Additionally, implementing Content Security Policy headers and proper HTML escaping mechanisms can help prevent the execution of malicious scripts. According to ATT&CK framework, this vulnerability maps to T1059.007 for scripting and T1566.001 for social engineering, as it enables attackers to leverage the application's legitimate functionality to deliver malicious payloads to unsuspecting users. The vulnerability also aligns with the principle of least privilege violations, as authenticated users should not be able to inject code that affects other users' sessions or data. Regular security assessments and code reviews focusing on input sanitization practices are essential to prevent similar vulnerabilities from emerging in other parts of the application. Organizations should also consider implementing web application firewalls and monitoring systems that can detect and block suspicious input patterns attempting to exploit this type of vulnerability.
