Fixed in
3.1.1
CVE-2026-5814 describes a SQL Injection vulnerability affecting PHPGurukul Online Course Registration versions 3.1 through 3.1. This flaw allows attackers to manipulate SQL queries through the 'regno' parameter within the /admin/check_availability.php file. Successful exploitation could result in unauthorized data access or modification. A patch is expected to address this issue.
Impact and Attack Scenarios
The SQL Injection vulnerability in PHPGurukul Online Course Registration allows an attacker to inject arbitrary SQL code into database queries. This can lead to a wide range of malicious activities, including unauthorized access to sensitive data such as user credentials, course details, and payment information. An attacker could potentially modify or delete data, leading to data integrity issues and disruption of service. The remote nature of the vulnerability means an attacker does not need to be on the same network as the server to exploit it. Given the potential for data exfiltration and manipulation, the blast radius of this vulnerability is significant, especially if the application handles sensitive user data or financial transactions.
Exploitation Context
This vulnerability has been publicly disclosed, increasing the likelihood of exploitation. The availability of public information makes it easier for attackers to identify and exploit the flaw. The exploit is considered relatively straightforward, requiring only manipulation of the 'regno' parameter. Currently, there is no indication of active exploitation campaigns targeting this specific vulnerability, but the public disclosure warrants immediate attention and mitigation.
