CVE-2023-1996Network attack vector

Browser script execution via reflected input

Published May 19, 2023 · Updated Feb 12, 2025

Reflected XSS in Dassault Systèmes 3DEXPERIENCE R2018x through R2023x allows remote attackers to execute script code. Dassault Systèmes has not disclosed the affected endpoint, input field, or server-side operation that reflects attacker-controlled content into a response. A victim must interact with a crafted request before the script runs in the victim's browser context, where it can read or alter page data.
