CVE-2025-52654 identifies an HTML Injection vulnerability in HCL MyXalytics version 6.6, classified under CWE-80. This vulnerability occurs when the application incorporates untrusted input into its output without proper sanitization or encoding, enabling attackers to inject arbitrary HTML content. Such injection can manipulate the rendered web page, potentially leading to unauthorized content display, phishing, or UI manipulation. The vulnerability requires an attacker to have limited privileges (PR:L) and necessitates user interaction (UI:R), indicating that exploitation is not fully remote or automatic. The CVSS 3.1 base score is 4.6 (medium), reflecting low to moderate impact on confidentiality and integrity, with no impact on availability. The attack vector is network-based (AV:N), and the scope remains unchanged (S:U). No patches or known exploits have been reported at the time of publication, but the vulnerability's presence in an analytics platform used for business intelligence and data visualization could allow attackers to mislead users or exfiltrate sensitive information through manipulated content. The lack of proper input validation or output encoding is the root cause, and the vulnerability is exploitable via crafted input fields or parameters that are reflected in the user interface.

For European organizations, the impact of this vulnerability primarily concerns the confidentiality and integrity of data presented through HCL MyXalytics dashboards or reports. Attackers could inject malicious HTML to alter displayed information, potentially misleading decision-makers or exposing sensitive data to unauthorized users. Although availability is not affected, the trustworthiness of analytics outputs could be compromised, affecting business operations reliant on accurate data insights. The requirement for authenticated access and user interaction limits the risk to internal or semi-trusted environments, but insider threats or compromised accounts could exploit this flaw. Organizations in sectors such as finance, manufacturing, and government that rely heavily on data analytics platforms may face reputational damage or regulatory scrutiny if manipulated data leads to incorrect decisions or data leaks. The absence of known exploits reduces immediate risk but does not eliminate the need for proactive mitigation.

To mitigate CVE-2025-52654, organizations should implement strict input validation and output encoding on all user-supplied data before rendering it in the application interface. Employing context-aware encoding (e.g., HTML entity encoding) prevents injection of executable HTML or scripts. Restricting user privileges to the minimum necessary reduces the likelihood of exploitation by low-privilege users. Monitoring and logging user inputs and application responses can help detect attempted injections. Since no official patch is currently available, consider deploying web application firewalls (WAFs) with custom rules to block suspicious payloads targeting MyXalytics interfaces. Additionally, educating users about phishing and suspicious content can reduce the effectiveness of injected malicious HTML. Regularly reviewing and updating security configurations and preparing for vendor patches once released is essential. Finally, isolating analytics platforms from direct internet exposure and enforcing strong authentication mechanisms will further reduce attack vectors.
