CVE-2023-4958 : Security Advisory and Response

This CVE-2023-4958 relates to a security vulnerability in Red Hat Advanced Cluster Security (RHACS) that allows for clickjacking in the web UI due to missing HTTP security headers.

Understanding CVE-2023-4958

This section delves deeper into the nature of CVE-2023-4958 and its potential impact.

What is CVE-2023-4958?

The vulnerability in RHACS involves the absence of certain security-related HTTP headers, which can be leveraged by attackers to execute clickjacking attacks. By tricking a legitimate RHACS user into visiting a malicious webpage that appears to point to valid RHACS endpoints, the attacker can hijack the user's account permissions for unauthorized actions.

The Impact of CVE-2023-4958

With this vulnerability, threat actors can exploit clickjacking to manipulate RHACS users into unintentionally granting access to their accounts. This can lead to unauthorized access, data theft, or other malicious activities within the RHACS environment.

Technical Details of CVE-2023-4958

This section provides more technical insights into the vulnerability, including how it can be exploited and the systems affected.

Vulnerability Description

The vulnerability lies in the lack of crucial security HTTP headers in RHACS, enabling attackers to conduct clickjacking attacks and deceive users into unknowingly compromising their account permissions.
