CVE-2025-52888: Critical XXE Vulnerability in Allure Report’s xunit-xml-plugin

Views: 150

Overview

The vulnerability referred to as CVE-2025-52888 is a critical XML External Entity (XXE) issue in Allure Report’s xunit-xml-plugin. This vulnerability exposes systems running Allure Report versions prior to 2.34.1 to potential system compromise or data leakage. Considering the wide usage of Allure 2 in multi-language test reporting, this vulnerability could potentially affect a broad range of systems.

How the Exploit Works

The exploit takes advantage of a vulnerability in the xunit-xml-plugin used by Allure 2. The XML parser (`DocumentBuilderFactory`) is not securely configured, enabling external entity expansion when processing test result .xml files. Attackers can exploit this to read arbitrary files from the file system and possibly trigger server-side request forgery (SSRF).

Conceptual Example Code

In this conceptual example, an attacker crafts a malicious XML file that references an external entity. The external entity points to a sensitive file on the server. When the vulnerable application processes this file, it inadvertently discloses the content of the sensitive file to the attacker.

<!DOCTYPE foo [
<!ELEMENT foo ANY >
<!ENTITY xxe SYSTEM "file:///etc/passwd" >]><foo>&xxe;</foo>

The attacker sends this XML file to a test endpoint that uses the vulnerable xunit-xml-plugin for processing. The server responds with the contents of the /etc/passwd file, disclosing sensitive information.
