CVE-2023-4958

Status: ModifiedMedium (6.1)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
