CVE-2024-22889

Vulnerability

Overview

CVE-2024-22889 describes an incorrect access control vulnerability in Plone version 6.0.9. Due to improper authorization checks, a remote attacker can list and view all files hosted on the website by sending a specially crafted request [1]. The root cause lies in the failure of Plone's permission system to properly restrict access to file listings, allowing unauthorized enumeration of stored content.

Attack

Vector and Prerequisites

An attacker can exploit this vulnerability from a remote network position without requiring authentication [1]. The attack is performed by crafting a specific HTTP request that bypasses the intended access controls. No special privileges or prior knowledge of the system is needed, making the attack surface broad for any publicly accessible Plone instance running the vulnerable version.

Impact

Successful exploitation enables an attacker to view and list all files hosted on the website [1]. This includes potentially sensitive documents, configuration files, or user-uploaded content. The exposure of the full file inventory can aid further attacks, such as information gathering for targeted exploits or data theft.

Mitigation

Plone version 6.0.9 is affected; users should upgrade to a newer, patched version of Plone to remediate this issue [2]. The Plone project maintains an active security process, and administrators are advised to follow official Plone security advisories for updates and migration paths [2].
