CVE-2020-13133
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 · uneditedTufin SecureChange prior to R19.3 HF3 and R20-1 HF1 are vulnerable to stored XSS. The successful exploitation requires admin privileges (for storing the XSS payload itself), and can exploit (be triggered by) unauthenticated users. All TOS versions with SecureChange deployments prior to R19.3 HF3 and R20-1 HF1 are affected. Vulnerabilities were fixed in R19.3 HF3 and R20-1 HF1
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 confidenceTufin SecureChange prior to R19.3 HF3 and R20-1 HF1 contains a stored XSS vulnerability where an authenticated administrator can inject malicious JavaScript into the application. This payload persists on the server and executes when triggered by unauthenticated users viewing the affected content, enabling client-side attacks such as session hijacking against those users.

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 Tufin SecureChange versionLocate the version information in the product UI under Help > About, or check the installation directory for a version file. Compare the displayed version number against the affected ranges.Affected if The installed version is R19-3 (any build), R20-1 (any build), or any version prior to R19-3.
-
Confirm administrator access existsVerify if there are administrator accounts configured in SecureChange. The stored XSS requires an authenticated administrator to inject the malicious payload.Affected if Administrator accounts are present in the system.
-
Inspect stored content visible to unauthenticated usersReview any public-facing or unauthenticated-accessible pages in SecureChange for user-supplied content fields (such as request titles, comments, or descriptions) that could contain injected script tags.Affected if Content submitted by administrators is visible to unauthenticated users without sanitization.
-
Check for anomalous script tags in application dataSearch application logs, database records, or exported data for suspicious script tags (such as <script> elements, javascript: URIs, or event handlers) in fields that accept user input.Affected if Unexpected JavaScript code is found stored in application fields.
A system is affected if it runs Tufin SecureChange version R19-3, R20-1, or any version prior to R19-3, and displays content submitted by administrators to unauthenticated users.
