CVE-2019-25514: Php SQLi — Patch Guide

Vendor-confirmed - CVE-2019-25514 is a high severity SQL injection in Jettweb PHP Hazir Haber Sitesi Scripti V3 that lets attackers extract all database contents including user credentials and administrative details. Apply the official patch from the vendor immediately to prevent data theft.

Overview

A significant SQL injection vulnerability has been identified in Jettweb PHP Hazir Haber Sitesi Scripti V3, a script for creating news websites. Tracked as CVE-2019-25514, this security flaw has been assigned a HIGH severity rating with a CVSS score of 8.2. It allows attackers to execute unauthorized commands on the website’s database, potentially leading to a full compromise of sensitive information.

Vulnerability Details

The vulnerability exists within the script’s search functionality. Specifically, the kelime parameter, which handles search terms in POST requests, does not properly sanitize user input. This oversight enables attackers to inject malicious SQL code. Using a technique called UNION-based SQL injection, an attacker can craft special search queries that trick the database into returning data it should not, such as user credentials, personal information, or administrative details.

Potential Impact

If successfully exploited, this vulnerability can have severe consequences:

• Data Theft: Attackers can extract the entire contents of the database, including user emails, hashed passwords, and private articles.
• Authentication Bypass: By extracting or manipulating login credentials, attackers can gain administrative access to the website’s backend.
• System Compromise: In some configurations, this could be a stepping stone to further attacks on the underlying server. Such breaches can lead to operational disruption, reputational damage, and regulatory penalties.

1. Apply the Official Patch: The primary remediation is to update to the latest patched version of the Jettweb PHP Hazir Haber Script. Contact the script vendor or developer to obtain the fixed release. There is no effective workaround; patching is essential.
2. Investigate for Compromise: If your site has been publicly accessible, review database and server logs for suspicious activity around the kelime parameter. Assume credentials may be compromised and plan to reset user passwords after applying the patch.
3. Implement General Security Practices: This flaw underscores the need for secure coding principles. Employ prepared statements and parameterized queries for all database interactions. Regularly update all third-party scripts and components.
