CVE-2024-7939
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 stored Cross-site Scripting (XSS) vulnerability affecting 3DSwym in 3DSwymer on Release 3DEXPERIENCE R2024x allows an attacker to execute arbitrary script code in user's browser session.
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 3DSwym component of 3DSwymer within the 3DEXPERIENCE R2024x release. Attackers can inject malicious script code that gets persistently stored and executes when users interact with the affected 3DSwym content in their browser sessions.

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 3DEXPERIENCE versionAccess the platform administration console or use the version check command for 3DEXPERIENCE R2024x. Common methods include checking the platform version in the About dialog or querying the installation directory for version metadata.Affected if The installed version is exactly r2024x (note the = operator in the affected range indicates an exact version match)
-
Confirm the 3DSwym component is accessibleLog into the 3DSwymer environment and navigate to the 3DSwym module. Verify whether users have access to create, edit, or view 3DSwym content such as posts, comments, or profiles.Affected if The 3DSwym component is installed and accessible to users, making the stored XSS payload vector viable
-
Examine 3DSwym content for suspicious script payloadsReview the 3DSwym database or content management interface for user-submitted entries containing HTML tags such as <script>, <img src=x onerror=...>, or other javascript: URLs. Use database queries or admin content review tools to inspect stored content.Affected if Any stored 3DSwym content contains unsanitized script tags or event handlers that could execute in user browsers
-
Check browser console for XSS errors when accessing 3DSwymOpen a browser developer console while browsing 3DSwym content. Look for console errors indicating executed script payloads or blocked XSS attempts.Affected if JavaScript executes unexpectedly when loading 3DSwym content, indicating successful injection
If the environment runs exactly 3DEXPERIENCE r2024x with the 3DSwym component enabled and accessible to users, the stored XSS vulnerability is present regardless of whether malicious content is currently visible.

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 proper input validation and output encoding for all user-supplied data in the 3DSwym component to prevent script execution. Consider applying context-aware sanitization or using a security library to neutralize HTML/script payloads.
