CVE-2018-25206

Vulnerability

Overview

KomSeo Cart 1.3 contains an SQL injection vulnerability in the edit.php script. The my_item_search POST parameter is not properly sanitized before being used in a SQL query, allowing an attacker to inject arbitrary SQL commands. This flaw is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) [3].

Exploitation

An attacker can exploit this vulnerability by sending a crafted POST request to /phpcart/edit.php with a malicious payload in the my_item_search parameter. No authentication is required, and the attack can be performed over the network. The exploit-db reference demonstrates both boolean-based blind and error-based injection techniques. For example, a boolean-based blind payload uses -5021' OR 3148=3148# to manipulate the query logic, while an error-based payload leverages MySQL FLOOR and COUNT(*) to extract data through error messages [2].

Impact

Successful exploitation allows an attacker to extract sensitive information from the database, such as user credentials, session data, or other confidential records. The CVSS v4 vector indicates high confidentiality impact, with no privileges required and no user interaction needed [3].

Mitigation

As of the publication date, no official patch has been released. The vendor site (sitemakin.com) appears to be inactive or for sale [1], suggesting the software may be abandoned. Users are advised to discontinue use of KomSeo Cart 1.3 or implement strict input validation and parameterized queries as a workaround.
