CVE-2025-28056: Critical SQL Injection Vulnerability in rebuild v3.9.0 to v3.9.3

Views: 473

Overview

The CVE-2025-28056 vulnerability has been discovered in the rebuild software, versions v3.9.0 through v3.9.3. This is a critical vulnerability, given its potential to compromise systems or lead to data leakage through SQL injection attacks. SQL injection is a well-known and widely exploited security flaw that allows attackers to manipulate the application’s database queries, which can result in unauthorized access, data corruption, and even system compromise. This vulnerability is particularly concerning due to its presence in the /admin/admin-cli/exec component, a critical part of the application’s administrative interface.

Vulnerability Summary

How the Exploit Works

The CVE-2025-28056 exploit takes advantage of a lack of proper input sanitization in the /admin/admin-cli/exec component of the rebuild software. By sending specially crafted input, an attacker can manipulate database queries to execute arbitrary SQL commands. This can lead to unauthorized access to sensitive data, modification of data, or even complete takeover of the system.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. Please note that this is a hypothetical scenario meant to illustrate the potential severity of the issue.

POST /admin/admin-cli/exec HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
cmd=DROP TABLE users; --

In this example, the attacker sends a HTTP POST request with a malicious SQL command that would drop the ‘users’ table from the database.

Mitigation

The best way to mitigate the CVE-2025-28056 vulnerability is to apply the vendor-provided patch immediately. If this is not possible, using web application firewalls (WAF) or intrusion detection systems (IDS) can offer temporary protection by detecting and blocking SQL injection attacks. Additionally, it is highly recommended to enforce the principle of least privilege for database access and to sanitize all user input to ensure that no SQL commands can be executed through user-provided data.
