Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
HCL BigFix ServiceNow is vulnerable to arbitrary code injection. A malicious authorized attacker could inject arbitrary code and execute within the context of the running user.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

HCL BigFix ServiceNow contains an arbitrary code injection vulnerability. An authenticated attacker with authorized access can inject malicious code that executes within the context of the running user account, potentially allowing privilege escalation or unauthorized system access.

MitigationApply vendor-supplied patches when available. Implement strict input validation and sanitization on all user-supplied data, and use parameterized queries or prepared statements to prevent code injection. Audit existing code for injection-prone patterns.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify HCL BigFix ServiceNow installation
    Locate the HCL BigFix platform installation and specifically look for the ServiceNow Data Flow component. Check installed programs or deployment documentation for presence of 'BigFix ServiceNow' or 'Servicenow Data Flow' modules.
    Affected if The HCL BigFix ServiceNow Data Flow component is installed on the system
  2. Determine installed version
    Use the BigFix administration console or check version information for the ServiceNow Data Flow component. Compare the installed version against the affected range (versions prior to 1.3).
    Affected if The installed version is lower than 1.3
  3. Verify ServiceNow integration is configured
    Check BigFix console or configuration files for active ServiceNow integration settings. Look for configured connections, endpoints, or data flow tasks pointing to ServiceNow instances.
    Affected if ServiceNow integration is enabled and actively configured with a ServiceNow instance
  4. Review authorized user access
    Examine user accounts and roles within BigFix that have authorized access to ServiceNow integration features. Check for users with permissions to create or modify data flow configurations.
    Affected if There are users with authorized access to ServiceNow data flow features who could potentially inject code
  5. Inspect data flow configurations
    Review existing data flow configurations, transformation rules, or scripts used for ServiceNow data synchronization. Look for any custom scripts, dynamic evaluations, or configurations that accept user-supplied input.
    Affected if Data flow configurations contain scripts, dynamic evaluations, or accept user-supplied input without validation

A system is affected if HCL BigFix ServiceNow Data Flow version is lower than 1.3 AND the ServiceNow integration feature is enabled and configured with authorized users who can access data flow configuration features.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 1.3 or later
Fixed in 1.3
Interim mitigation

Apply vendor-supplied patches when available. Implement strict input validation and sanitization on all user-supplied data, and use parameterized queries or prepared statements to prevent code injection. Audit existing code for injection-prone patterns.

Recommended fix Moderate confidence

BigFix ServiceNow Data Flow version 1.3

  1. Verify current BigFix ServiceNow Data Flow version by checking the application console or installed components
  2. Contact HCL Support at support.hcltechsw.com to obtain the version 1.3 upgrade package or patch
  3. Review HCL BigFix ServiceNow Data Flow 1.3 release notes for upgrade prerequisites
  4. Back up current configuration and data before proceeding with upgrade
  5. Apply version 1.3 upgrade following HCL-provided installation documentation
  6. Verify successful upgrade by confirming the version in the application
  7. Test critical ServiceNow data flow operations to ensure functionality is intact
Caveat Review release notes for any configuration or integration changes between previous version and 1.3
