HCL vulnerabilities and threats

HCL AION is affected by a vulnerability where encryption is not enforced for certain data transmissions or operations. This may expose sensitive information to potential interception or unauthorized access under specific conditions.

HCL BigFix SCM Reporting version 11.0.5 uses an outdated and unsupported version of the jQuery 1.x library. Since jQuery 1.x is end-of-life and no longer receives security updates, this exposes the application to known security weaknesses. This increases the risk of client-side attacks such as Cross-Site Scripting (XSS) or manipulation through vulnerable third-party components. The vulnerability is tracked as CVE-2026-21821 with a high severity score of 8.3. No official patch or remediation guidance is currently available from the vendor.

A missing authorization vulnerability in HCL BigFix WebUI allows an authenticated user without proper permissions to view sensitive environmental information via direct URL access to the unauthorized page.

An improper authorization vulnerability in HCL BigFix WebUI allows an authenticated user without Master Operator privileges to access internal data (site names, versions, and configuration variables) and bypass privilege requirements via unprotected endpoints lacking adequate security headers.

HCL BigFix Service Management (SX) is affected by a Broken Access Control vulnerability leading to privilege escalation. This could allow unauthorized users to gain elevated privileges, bypassing intended access restrictions. This may result in exposure of sensitive data or unauthorized system modifications

HCL BigFix Service Management (SM) is vulnerable to information exposure due to improper error handling within its reporting module. It was observed that supplying an invalid or out-of-range value to the consumer_company parameter during a report-viewing request causes the application to trigger an unhandled exception.

HCL BigFix Service Management (SM) is susceptible to a Root File System Not Mounted as Read-Only. An improperly configured root file system may allow unintended modifications to critical system components, potentially increasing the risk of system compromise or unauthorized changes.

HCL BigFix Service Management (SM) is affected by an Information Disclosure – Server Banner issue was identified. Exposed server banners may reveal software versions and system details, potentially aiding attackers in targeting known vulnerabilities.

HCL BigFix Service Management (SM) is affected by use of a vulnerable WSGI Server was identified. Deploying an outdated or insecure WSGI server may expose the application to known security weaknesses, potentially increasing the risk of exploitation and unauthorized access.

HCL BigFix Service Management (SM) is vulnerable to insufficiently protected credentials for a short duration while communicating with a backend, internal application which could allow an attacker to potentially misuse them, if exfiltrated. .

HCL BigFix Service Management (SM) does not adequately sanitize or safely render spreadsheet files (CSV, XLS, XLSX) before processing or distributing them. An attacker could populate data fields which, when saved to a CSV file, may attempt information exfiltration or other malicious activity when automatically executed by the spreadsheet software. Note that current versions of Excel warn users of untrusted content.

HCL BigFix Service Management (SM) application fails to strip EXIF metadata from uploaded images. This could lead to confidentiality and privacy risks if sensitive location information is unintentionally shared. .

HCL BigFix Service Management (SM) had directories that were not linked or publicly visible but could be accessed directly. This could allow an increased risk of information disclosure or misuse of sensitive functionality.

HCL BigFix Service Management (SM) is affected by a security misconfiguration due to a missing or insecure “X-Content-Type-Options” header. This could allow browsers to perform MIME-type sniffing, potentially causing malicious content to be interpreted and executed incorrectly.

HCL BigFix Service Management (SM) is affected by a security misconfiguration vulnerability due to CSP header. This could allow attackers to inject malicious scripts increasing the risk of cross-site scripting (XSS) and potential exposure of sensitive information.

HHCL BigFix Service Management (SM) is affected by a Cross‑Site Request Forgery (CSRF) vulnerability. This could lead to unauthorized changes or exposure of sensitive data.

HCL BigFix RunBookAI is affected by a Continued availability of Less-Secure “Input Text” Vulnerability . A component contains a security weakness in its input handling implementation, increasing the risk of misconfiguration and operational errors.

HCL BigFix RunBookAI is affected by a Unvalidated Command Input / Potential Command Smuggling vulnerability. A flaw in a component's input handling was identified that could permit unauthorized command execution.

HCL DFXAnalytics is affected by an Insecure Security Header Configuration vulnerability where the application utilizes the outdated X-XSS-Protection header, which could allow an attacker to exploit browser-specific rendering flaws or bypass security controls that should instead be managed by a robust Content Security Policy (CSP).

HCL DFXAnalytics is affected by an Improper Error Handling vulnerability where the application exposes detailed stack traces in responses, which could allow an attacker to gain insights into the application's internal structure, code logic, and environment configurations.
