AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability allows an authenticated administrator, who does not have super administrator privileges, to create a maintenance period that contains a malicious JavaScript payload.
When any user opens the tooltip for that maintenance period in the Host navigator widget, the JavaScript payload is executed.
This means the attacker can perform unauthorized actions depending on which user views the tooltip.
How can this vulnerability impact me? :
The impact of this vulnerability is that an attacker with limited administrative privileges can execute arbitrary JavaScript code in the context of other users.
This can lead to unauthorized actions being performed on behalf of those users, potentially compromising system integrity, confidentiality, or availability.
