CodeAstro Online Job Portal SQL Injection Vulnerability in Jobs Administration Delete Function

A SQL injection vulnerability has been identified in CodeAstro Online Job Portal version 1.0. The issue arises in the jobs administration delete function, specifically within the delete-jobs.php file. The vulnerability allows remote attackers to manipulate the 'id' parameter, injecting malicious SQL code that is executed without proper validation or sanitization. This exploitation could lead to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Such actions could disrupt services and compromise overall system security.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the delete-jobs.php file with an injected SQL payload in the 'id' parameter. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can further enhance system security.
