CVE-2023-22518 Scanner Detail

Atlassian Confluence Server is a widely used collaboration tool for teams to share knowledge efficiently. This platform enables users to create, collaborate, and organize all their work in one place. Confluence is utilized across various sectors, including technology, finance, and education, by small teams to large enterprises. Its flexibility and integration with Atlassian’s other tools like Jira make it a central component for project management and documentation. The vulnerability affects all versions of Confluence Data Center and Server, but Atlassian Cloud sites are not impacted.

The vulnerability in Atlassian Confluence Server involves improper authorization, which can lead to unauthorized actions on the server without proper authentication. This critical security issue allows attackers to bypass security measures and perform restricted operations. The flaw has a significant impact on the confidentiality, integrity, and availability of the system, making it a high-risk vulnerability. It is essential for users to address this vulnerability to protect their Confluence Server instances from potential exploitation.

This security flaw is present in the setup-restore functionality of the Atlassian Confluence Server. Attackers can exploit this vulnerability by sending a specially crafted HTTP request to the server. The request attempts to upload an invalid (empty) zip file through the 'setup-restore.action' endpoint. This method is intended to check for the vulnerability without causing data loss or database reset. In a real attack scenario, a malicious file could be used, causing more severe impacts.

Exploiting this vulnerability could allow attackers to gain unauthorized access to the Confluence Server, leading to data theft, unauthorized changes, or even full system compromise. This could result in the exposure of sensitive information, disruption of operations, and a significant impact on the organization’s reputation. Addressing this vulnerability is critical to prevent potential exploitation and safeguard the confidentiality, integrity, and availability of the Confluence Server.
