HCL vulnerabilities and threats

CVE-2026-108013 is a vulnerability in HCL Software BigFix Platform related to the use of an outdated Mozilla CA certificate bundle. Versions of the bundle dated before 2026/10/20 trust certificates whose private keys have been compromised, allowing an on-path attacker to impersonate remote servers and tamper with files downloaded by the application. The issue is resolved by updating to the bundle version dated 2026/10/20 or later, available starting from BES Support v1520.

HCL AppScan Azure Boards Plugin is affected by a Cleartext Transmission of Sensitive Information vulnerability when configured to communicate with the AppScan server over HTTP. This could allow an attacker to intercept credentials or authentication tokens during transmission. The plugin has been updated to display a warning when HTTP is used and recommend HTTPS for secure communication.

CVE-2026-21811 is an information disclosure vulnerability in HCL AppScan Azure Boards Plugin that may expose secrets in plaintext during pipeline execution. These secrets can be revealed through task outputs, debug logs, environment variable dumps, or build agent scripts, despite being masked in the user interface. The vulnerability has a low severity rating and requires privileged access to exploit.

CVE-2026-67165 is a cross-site scripting (XSS) vulnerability in HCL Connections. It allows an attacker to inject and execute arbitrary script code in the browser of a user. This can lead to theft of cookie-based authentication credentials and compromise of the user's account. The vulnerability has a medium severity with a CVSS score of 5.4. No affected versions or patch information are provided.

HCL BigFix Service Management is affected by an Improper Input Validation vulnerability, which could allow an attacker to supply unexpected or malformed data, enabling processing errors, business logic bypasses, and unintended application behavior.

HCL AION is affected by a vulnerability in which the Content-Security-Policy (CSP) HTTP response header is not configured. CSP helps prevent attacks such as Cross-Site Scripting (XSS) by restricting the sources from which scripts, styles, and other resources can be loaded. The absence of this header may reduce the effectiveness of browser-based security controls, potentially resulting in unintended behavior or negative security impacts under certain conditions.

HCL BigFix Service Management is affected by an Improper Input Validation vulnerability, which could allow an attacker to inject unvalidated, malformed data into the application, enabling potential injection attacks or errors in downstream processing systems.

HCL BigFix Service Management is affected by an Information Disclosure vulnerability the application returns sensitive information in error messages when invalid inputs are sent to certain API endpoints . This information could enable an attacker to facilitate further attacks.

HCL BigFix Service Management is affected by an Information Disclosure vulnerability because an exposed API endpoint exposes sensitive internal database information. This information could enable an attacker to facilitate targeted database attacks.

HCL BigFix Service Management is affected by an Information Disclosure vulnerability because two exposed API endpoints return sensitive data. This information could enable an attacker to launch further, more serious attacks.

HCL BigFix Service Management is affected by an Insecure Cookie Attribute Configuration vulnerability, which could allow an attacker to exploit missing security attributes such as SameSite, HttpOnly, Secure, and restrictive Paths, enabling Cross-Site Request Forgery (CSRF), session hijacking via Cross-Site Scripting (XSS), and unauthorized access.

HCL BigFix Service Management is affected by an Information Disclosure vulnerability, which could allow an unauthenticated attacker to analyze publicly accessible JavaScript files, enabling the discovery of hidden administrative API endpoints for further targeted exploitation.

HCL BigFix Service Management is affected by an Insecure Communication vulnerability, which could allow an attacker with internal network access to intercept unencrypted HTTP traffic between backend services, enabling the extraction of sensitive data and potential man-in-the-middle (MitM) attacks.

HCL BigFix Service Management contains a stored Cross-Site Scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the application. These scripts execute when other users view the affected pages, potentially leading to session hijacking and theft of sensitive information. The vulnerability has a high severity rating with a CVSS score of 7.2. No specific affected versions or patch information are provided.

iControl is affected by a Session Timeout vulnerability, which could allow an attacker to exploit an unattended or abandoned active session, enabling unauthorized access to the application and the ability to perform actions on behalf of the victim.

iControl is affected by a Missing Secure Attribute vulnerability, which could allow an attacker to intercept cookies transmitted over unencrypted HTTP connections, enabling the unauthorized extraction of sensitive information such as session identifiers.

iControl is affected by an Improper Error Handling vulnerability, which could allow an unauthenticated attacker to trigger verbose database and system errors, enabling the disclosure of sensitive internal infrastructure details used to plan advanced targeted attacks.

iControl is affected by an insecure Cross-Origin Resource Sharing (CORS) policy vulnerability, which could allow a malicious website to execute cross-origin requests with included credentials, enabling an attacker to access and exfiltrate sensitive data within the context of the victim's active session.

iControl is affected by a Broken Access Control vulnerability, which could allow an attacker to exploit missing authentication checks or insecure direct object references (IDOR), enabling privilege escalation and the unauthorized modification or deletion of sensitive application data.

HCL Digital Experience is affected by improper input sanitation.  This can result in HTML injection which could be leveraged in content spoofing from a trusted domain. Apply HCL Digital Experience 9.5 CF238 or later to address this.
