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 · high confidenceThis is a clickjacking vulnerability in HCL BigFix OSD Bare Metal Server version 311.12 and lower where attackers can overlay transparent or opaque layers to trick authenticated users into clicking on hidden buttons or links, causing involuntary redirects to attacker-controlled domains.

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.
-
Identify the installed version of HCL BigFix OSD Bare Metal ServerLocate the version through the product's built-in version information, system inventory, or BigFix console. This is typically found in the product interface, installation files, or via BigFix client queries.Affected if The installed version is 311.12 or lower (any version up to and including 311.12).
-
Verify the X-Frame-Options HTTP response headerSend a request to the BigFix OSD Bare Metal Server web interface and inspect the HTTP response headers for the presence and value of X-Frame-Options.Affected if The X-Frame-Options header is missing, set to a value other than DENY or SAMEORIGIN (such as ALLOW), or not configured at all.
-
Verify Content-Security-Policy frame-ancestors directiveInspect the Content-Security-Policy HTTP response header from the BigFix OSD Bare Metal Server web interface to determine if the frame-ancestors directive is present and what sources it allows.Affected if The CSP header is missing entirely, or the frame-ancestors directive is absent, or it permits untrusted/external domains (such as allowing generic wildcards or specific attacker-controlled domains).
A user is affected if their BigFix OSD Bare Metal Server version is 311.12 or lower AND the application can be embedded in iframes due to missing or weak X-Frame-Options and CSP frame-ancestors protections.

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 X-Frame-Options: DENY or SAMEORIGIN header, or configure Content-Security-Policy with frame-ancestors directive to prevent the application from being embedded in iframes.
