Description

In Red Hat Advanced Cluster Security (RHACS), it was found that some security related HTTP headers were missing, allowing an attacker to exploit this with a clickjacking attack. An attacker could exploit this by convincing a valid RHACS user to visit an attacker-controlled web page, that deceptively points to valid RHACS endpoints, hijacking the user's account permissions to perform other actions.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality none, integrity low, availability low.
