Multiple Atlassian products (JIRA before 5.0.1; Confluence before 3.5.16, 4.0 before 4.0.7, and 4.1 before 4.1.10; FishEye and Crucible before 2.5.8, 2.6 before 2.6.8, and 2.7 before 2.7.12; Bamboo before 3.3.4 and 3.4.x before 3.4.5; and Crowd before 2.0.9, 2.1 before 2.1.2, 2.2 before 2.2.9, 2.3 before 2.3.7, and 2.4 before 2.4.1) do not properly restrict the capabilities of third-party XML parsers. This allows remote attackers to exploit XML External Entity (XXE) vulnerabilities to read arbitrary files or cause denial of service via crafted XML input.

This repository contains a single Metasploit auxiliary module targeting Atlassian Crowd servers vulnerable to CVE-2012-2926 (XML External Entity Expansion). The module exploits a flaw in the SOAP interface's XML parsing, allowing an attacker to read arbitrary files from the server's filesystem by sending a specially crafted SOAP request containing an external entity referencing the desired file. The module is written in Ruby and is structured as a typical Metasploit auxiliary scanner, with options to specify the target URI, port, and file to read. The default configuration targets the /crowd/services endpoint on port 8095 and attempts to read /etc/passwd. The exploit is a proof-of-concept for file disclosure and does not provide code execution or other post-exploitation capabilities. The only file in the repository is the Metasploit module itself.
