CVE-2018-25172: Pedidos SQLi — Patch Guide

Overview

A critical SQL injection vulnerability exists in Pedidos 1.0, an order management system. This flaw allows attackers without any login credentials to execute malicious commands on the application’s database by manipulating a specific parameter in web requests.

Vulnerability Details

The vulnerability is located in the ajax/load_proveedores.php endpoint. Attackers can send specially crafted HTTP GET requests containing malicious SQL code within the q parameter. This code is not properly filtered by the application and is passed directly to the database. As a result, an attacker can read, modify, or delete database information. Exploitation is straightforward and can be automated, posing a significant risk.

Potential Impact

The primary risk is a complete compromise of the database. Attackers can:

• Exfiltrate Sensitive Data: Extract all data, including supplier details, customer information, order history, and potentially administrative credentials.
• Disrupt Operations: Modify or delete critical data, leading to application malfunction and business disruption.
• Gain Foothold: Use extracted information or database permissions to launch further attacks on the network. Successful exploitation could lead to a severe data breach, financial loss, and reputational damage. For examples of real-world consequences, recent data breach reports are available at breach reports.

Remediation and Mitigation

The most effective action is to apply a vendor-provided patch immediately. If a patch is not available, consider the following urgent steps:

1. Immediate Isolation: If possible, restrict network access to the affected Pedidos application until it can be patched or updated.
2. Input Validation: Implement strict input validation and parameterized queries (prepared statements) for all user-supplied input, especially for the q parameter and similar search functionalities.
3. Web Application Firewall (WAF): Deploy or configure a WAF with rules to block SQL injection patterns. This can serve as a temporary virtual patch.
4. Upgrade or Replace: Contact the software vendor for a fixed version. If the software is no longer supported, migrating to a maintained alternative is strongly advised.
