How the CVE Works
This vulnerability exists in the 3DSwym community collaboration component of the 3DEXPERIENCE platform. An authenticated attacker can inject malicious JavaScript code into specific application fields, such as forum posts or user comments, which are stored by the server. When other users, including administrators, later view the page containing the injected payload, the malicious script is executed within their browser session. This execution occurs in the context of the victim’s session, allowing the attacker to steal session cookies, perform actions on behalf of the user, or deface the application. The attack is “stored” because the payload is permanently kept on the server and served to users, making it persistent and potentially affecting multiple victims.
