The vulnerability, if exploited, could allow an authenticated miscreant (with privilege of "aaConfigTools") to tamper with App Objects' help files and persist a cross-site scripting (XSS) injection that when executed by a victim user, can result in horizontal or vertical escalation of privileges. The vulnerability can only be exploited during config-time operations within the IDE component of Application Server. Run-time components and operations are not affected.
