CVE-2023-27583 : Security Advisory and Response

This CVE-2023-27583 involves a vulnerability in PanIndex that uses a hardcoded cryptographic key, potentially allowing an attacker to sign a JWT token and perform unauthorized actions as a user with admin privileges.

Understanding CVE-2023-27583

This section delves into the details of the CVE-2023-27583 vulnerability in PanIndex.

What is CVE-2023-27583?

PanIndex, a network disk directory index, is affected by CVE-2023-27583 where a hardcoded JWT key 'PanIndex' is utilized. This vulnerability enables attackers to use the hardcoded key to sign JWT tokens and execute actions as an admin user.

The Impact of CVE-2023-27583

The impact of this critical vulnerability is significant, with high confidentiality, integrity, and availability impacts associated. Attackers can exploit the vulnerability without requiring any privileges, leading to severe consequences if not addressed promptly.

Technical Details of CVE-2023-27583

This section highlights the technical aspects of the CVE-2023-27583 vulnerability.

Vulnerability Description

The vulnerability arises from the use of a hardcoded cryptographic key in PanIndex, allowing unauthorized access and actions with admin privileges. Version 3.1.3 includes a patch to address this issue.

Affected Systems and Versions
