Technical details
A CSRF vulnerability in the EAI (Enterprise Application Integration) component of Siebel CRM Integration requires user interaction and network access via HTTP. An unauthenticated attacker can craft a request that, when triggered by a user visiting a malicious page, performs unauthorized read and write operations on Siebel CRM data. The scope change indicates the compromise may affect systems beyond Siebel CRM Integration itself.
