CVE-2020-15885
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 · uneditedA Cross-Site Scripting (XSS) vulnerability in the comment module before 4.0 for MunkiReport allows remote attackers to inject arbitrary web script or HTML by posting a new comment.
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 confidenceA stored Cross-Site Scripting (XSS) vulnerability exists in the comment module of MunkiReport prior to version 4.0. The module fails to properly sanitize user-submitted comment input, allowing attackers to inject malicious JavaScript or HTML that executes in the browsers of other users viewing the comments.

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 MunkiReport versionLocate the version information for your MunkiReport installation. This is typically found in the application itself (often on an admin or about page), in a version file within the installation directory, or via the application's API endpoint that reports version details.Affected if Your installed version is any release prior to version 4.0 (e.g., 3.x, 2.x, etc.)
-
Confirm comment module is activeVerify that the comment module is enabled and accessible in your MunkiReport deployment. Check the module configuration or list of active modules to confirm the comment functionality is present.Affected if The comment module is enabled and accessible to users
-
Check for existing commentsAccess the comment module interface and review any existing comments that have been submitted. Look for the list of user comments displayed in the application.Affected if There are any stored comments in the system that could contain malicious payloads
-
Inspect comment input handlingIf you have administrative access, examine how comments are processed and stored. Look for evidence of input sanitization or lack thereof in the comment submission flow.Affected if User-submitted comment content is stored and displayed without proper sanitization or encoding
You are affected if your MunkiReport version is prior to 4.0 AND the comment module is enabled, as this combination allows stored XSS to be exploited through unsanitized comment input.

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 data4.0
Upgrade MunkiReport to version 4.0 or later, which includes proper input sanitization for the comment module. Until upgraded, disable or restrict the comment feature.
