CVE-2025-52619
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 SaaS Authentication Service is affected by a sensitive information disclosure. Under certain conditions, error messages disclose sensitive version information about the underlying platform.
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 SaaS Authentication Service contains a sensitive information disclosure vulnerability where error messages inadvertently expose version information about the underlying platform. This version information could aid attackers in fingerprinting the system and identifying specific vulnerabilities associated with that platform version.
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 checksWork through these to decide whether this CVE applies to you.
-
Locate the installed HCL BigFix SaaS versionAccess the BigFix administrative console or use the platform's API/CLI tools to retrieve the current software version. This is typically found in the system information, about page, or version settings of the management interface.Affected if The displayed version number is lower than 8.1.14 (for example, 8.1.13, 8.1.0, or any version before 8.1.14).
-
Trigger an authentication error conditionSubmit an invalid login request, provide incorrect credentials, or intentionally cause an authentication failure to generate an error response from the Authentication Service.Affected if The returned error message, response body, headers, or stack trace contains version numbers, platform details, or build identifiers that reveal the underlying system version.
-
Inspect error responses for version disclosureCapture and examine the full HTTP response (including any JSON, XML, or HTML content) from error-generating endpoints. Look for strings that resemble version numbers, product names with version suffixes, or platform metadata.Affected if Error responses include version strings such as platform version numbers, component versions, or any information that would help an attacker identify the specific platform version in use.
You are affected if your BigFix SaaS version is below 8.1.14 AND error messages returned by the Authentication Service expose version or platform identification details.

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 · scoped8.1.14
Implement error message sanitization to remove version and platform identification details before returning responses to users. Ensure generic, non-revealing error messages are displayed.
8.1.14 or later
- Access the HCL BigFix support portal at support.hcl-software.com
- Locate and download HCL BigFix SaaS version 8.1.14 or later
- Apply the upgrade to your BigFix SaaS instance following HCL's standard upgrade procedures
- Verify the upgrade was successfully applied
- Test that error messages no longer disclose sensitive version information about the underlying platform
