Description Preview
Overview
This vulnerability (CWE-425: Direct Request) allows attackers to bypass intended access restrictions and access files that should be protected. By exploiting the vulnerability in the /s/ endpoint, an attacker can read arbitrary files from the server's file system without requiring authentication. This could lead to exposure of sensitive configuration files, credentials, or other confidential information stored on the server. The vulnerability is particularly severe because it can be exploited pre-authentication, meaning an attacker doesn't need valid credentials to exploit it.
Remediation
Organizations running affected versions of Atlassian Confluence Server should immediately upgrade to a patched version:
- For versions before 7.4.10, upgrade to version 7.4.10 or later
- For versions 7.5.0 through 7.12.2, upgrade to version 7.12.3 or later
If immediate patching is not possible, consider implementing network-level controls to restrict access to the Confluence Server, particularly to the vulnerable /s/ endpoint. Monitor for suspicious access attempts to this endpoint, especially those that might be attempting to access files outside the normal web content directories.
