What to do
AI-suggested
Since the vulnerability requires authenticated access with 'aaConfigTools' privilege and occurs only during configuration-time operations, restricting access to these privileges and limiting user interaction with the IDE component can reduce risk. Monitor vendor advisories for any forthcoming patches or official remediation guidance.
Description
This vulnerability allows an authenticated user with the 'aaConfigTools' privilege to tamper with App Objects' help files during configuration-time operations within the IDE component of the Application Server. Successful exploitation can persist a cross-site scripting (XSS) injection that may lead to horizontal or vertical privilege escalation when executed by a victim user. Run-time components and operations are not affected by this vulnerability.
