D-LINK SQL Injection Vulnerability Let Attacker Gain Admin Privileges

A security flaw called SQL injection has been uncovered in the D-Link DAR-7000 device.

SQL injection is a malicious attack that exploits vulnerabilities in web applications to inject malicious SQL statements and gain unauthorized access to the database.

This technique allows an attacker to view, modify, and delete data from the database, which can be a significant threat to the confidentiality, integrity, and availability of the data.

SQL injection attacks can target various types of databases, including MySQL, MSSQL, Oracle, and many others.

Malicious actors can exploit the vulnerability to obtain administrative privileges and execute unauthorized commands on the affected devices.

An official CVE number, CVE-2023-42406, has been assigned to identify and track a newly discovered vulnerability.

The severity level of this vulnerability is currently under analysis to determine the potential impact it could have.

On GitHub, a Proof-of-Concept (PoC) has been published to demonstrate how the vulnerability can be exploited.

CVE-2023-42406 – Proof of concept

According to the reports shared with Cyber Security News, this vulnerability exists in the /sysmanage/editrole.php endpoint, which is vulnerable to SQL injection.

A potential hacker can exploit a vulnerability by sending a specifically crafted payload, such as “hid_id=(select*from(select(sleep(3)))a)”, to the target endpoint. This can result in a successful exploitation of the system.

A complete report on this proof-of-concept has been published by GitHub, which provides detailed information about the exploitation.
