CVE-2023-2139Public exploitNetwork attack vector

Browser script execution via unencoded error message

Published Apr 21, 2023 · Updated Feb 4, 2025

Reflected XSS in Dassault Systèmes DELMIA Apriso 2017 through 2022 allows remote attackers to run script in a victim's browser. The logon error renderer inserts the Message query parameter into the page without HTML encoding; an authenticated Portal path does likewise. Exploitation requires a victim to open a crafted link, and the script runs in that victim's Apriso browser context.
