CVE-2019-6180 in XClarity Administrator
Summary
by MITRE
A stored cross-site scripting (XSS) vulnerability was reported in Lenovo XClarity Administrator (LXCA) versions prior to 2.5.0 that could allow an administrative user to cause JavaScript code to be stored in LXCA which may then be executed in the user's web browser. The JavaScript code is not executed on LXCA itself.

The vulnerability identified as CVE-2019-6180 represents a critical stored cross-site scripting flaw within Lenovo XClarity Administrator version 2.4.0 and earlier releases. This security weakness resides in the administrative web interface of LXCA, which is designed to manage and monitor enterprise server infrastructure. The vulnerability stems from inadequate input validation and output encoding mechanisms within the application's user interface components that handle administrative data entry and display operations.
The technical exploitation of this vulnerability occurs when an authenticated administrative user submits malicious JavaScript code through the LXCA interface. This code gets stored within the application's database or storage mechanisms and subsequently served to other users who access the affected pages. The stored payload executes within the victim's web browser context, creating a persistent XSS attack vector. The vulnerability specifically affects the web-based administrative console where users can configure various system parameters, manage inventory, and perform monitoring tasks. The flaw demonstrates poor security practices in data sanitization and demonstrates how administrative interfaces can become attack vectors when proper input validation is absent.
The operational impact of this vulnerability extends beyond simple script execution, as it allows attackers with administrative privileges to potentially escalate their access within the enterprise environment. An attacker who gains administrative access through this vulnerability could manipulate user sessions, steal sensitive credentials, redirect users to malicious sites, or even execute arbitrary code within the browser context of other administrators. This creates a significant risk for enterprise environments where LXCA is used to manage critical infrastructure components such as servers, storage systems, and networking equipment. The vulnerability also poses a risk to the integrity of the monitoring and management data within the system, potentially leading to unauthorized modifications of system configurations or data manipulation.
The vulnerability aligns with CWE-79 which describes cross-site scripting flaws in web applications, and maps to ATT&CK technique T1059.007 for script execution through web interfaces. Organizations using LXCA versions prior to 2.5.0 should implement immediate mitigations including applying the vendor-provided patch, implementing network segmentation to limit access to the administrative interface, and conducting thorough security assessments of all administrative user accounts. Additional protective measures include implementing web application firewalls, monitoring for suspicious administrative activities, and establishing strict access controls for administrative accounts. The security community has identified this as a particularly dangerous vulnerability because it leverages legitimate administrative functionality to deliver malicious payloads, making detection more challenging and the potential impact more severe. Organizations should also consider implementing regular security training for administrative users to recognize social engineering attempts that might lead to privilege escalation.
