CVE-2025-31951
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 · uneditedHCL 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.
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 confidenceHCL BigFix RunBookAI contains an unvalidated command input vulnerability where a flaw in a component's input handling permits unauthorized command execution. This is a command injection/smuggling issue where user-supplied input is not properly validated or sanitized before being used in system command execution contexts.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm HCL BigFix RunBookAI installationLocate the BigFix RunBookAI installation directory or check installed programs list. On Windows, look in Program Files for 'HCL' or 'BigFix' folders containing RunBookAI components. On Linux, check /opt/BigFix or similar installation paths.Affected if RunBookAI is present on the system and the vulnerable component is enabled.
-
Determine installed RunBookAI versionCheck the version by examining the RunBookAI application files, such as a version manifest, about dialog, or running 'version' commands if available from the installation directory. Compare against the affected version range provided by HCL.Affected if The installed version falls within the vulnerable version range and the affected input handling component is in use.
-
Identify if command execution feature is enabledReview RunBookAI configuration files and settings to determine whether the automation or command execution components that accept user input are active. Look for features related to workflow automation, script execution, or API endpoints that process user commands.Affected if The component handling command execution with unvalidated input is enabled and accessible.
-
Check for exposed network interfacesExamine configuration files for exposed listening ports, API endpoints, or web service configurations that accept user-supplied input for command processing. Look for settings in config.xml, settings.conf, or similar configuration files.Affected if The vulnerable input handling component is exposed via network accessible services without additional access controls.
-
Review for command injection indicatorsExamine RunBookAI logs for unexpected command execution patterns, unusual system calls, or input validation failures. Check audit logs for commands containing shell metacharacters that may indicate injection attempts.Affected if Logs show command execution with unsanitized input patterns or unexpected command structures.
A user is affected if HCL BigFix RunBookAI is installed with the vulnerable version range, the command execution component is enabled, and the input handling interface is accessible.

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.
From vendor dataImplement strict input validation and sanitization for all user-supplied input before use in command execution contexts. Follow secure coding practices to prevent command injection, and apply any vendor-provided patches when available.
