SEO Panel Blind SQL Injection Vulnerability in 'order_col' Parameter

A blind SQL injection vulnerability has been identified in SEO Panel versions prior to 4.9.0. The issue resides in the archive.php page, where authenticated attackers can manipulate database queries through the 'order_col' parameter. Exploitation of this vulnerability allows attackers to inject malicious SQL code, potentially leading to unauthorized data access or modification. The vulnerability can be exploited using sqlmap, a popular SQL injection automation tool, to extract sensitive database information.

Impact

Exploitation of this vulnerability allows for time-based blind SQL injection, where an attacker can inject SQL payloads that, when executed, cause a delay in the application's response. This technique can be used to infer information about the database and its contents. Additionally, according to VulnCheck, this vulnerability could lead to reading, updating, and deleting arbitrary database data, and possibly executing commands on the underlying operating system.

Reproduction

To reproduce this vulnerability, log into the SEO Panel admin interface and navigate to the archive.php page. Once there, modify the 'order_col' parameter in the request URL by replacing its value with a crafted SQL payload that exploits the application's SQL query handling. After sending the request, observe the application's response time; a delay indicates successful exploitation. This vulnerability can also be automated with sqlmap by specifying the 'order_col' parameter payload.

Remediation

Users are advised to upgrade to SEO Panel version 4.9.0 or later, where this vulnerability has been fixed.
