CVE-2020-12779
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 · uneditedCombodo iTop contains a stored Cross-site Scripting vulnerability, which can be attacked by uploading file with malicious script.
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 confidenceCombodo iTop is vulnerable to a stored Cross-site Scripting (XSS) attack via file uploads. An attacker can upload a file containing malicious script that gets persisted on the server and executes when other users access or view the uploaded file, potentially compromising their sessions or stealing credentials.

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 iTop versionCheck your iTop installation's version number (typically found in the application header, about page, or version configuration file)Affected if The version is less than 2.7.0 or exactly equals 2.7.0
-
Confirm file upload functionality is accessibleDetermine if the file upload feature is enabled in your iTop installation - check if users with appropriate permissions can access the attachment or document upload functionalityAffected if File upload capability is available to at least some users in the system
-
Locate uploaded files directoryIdentify where iTop stores uploaded files (typically in the data or attachments directory)Affected if The upload directory exists and contains user-uploaded files
-
Inspect uploaded files for script contentExamine files in the upload storage area for any that contain JavaScript tags, script elements, or other XSS payload patterns in their content or metadataAffected if Any uploaded files contain executable script content that could be triggered when viewed by other users
Your environment is affected if you are running iTop version 2.7.0 or any version below 2.7.0 AND the file upload feature is enabled and accessible to users in your deployment.

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 data2.7.0
Implement strict file upload validation including file type restrictions, filename sanitization, and Content Security Policy headers. Additionally, sanitize or strip script content from uploaded file metadata and content before storage and before display to users.
