CVE-2025-8326: Critical SQL Injection Vulnerability in Exam Form Submission 1.0

Welcome back to the blog, security enthusiasts! Today we're diving into CVE-2025-8326, a critical SQL Injection vulnerability affecting Exam Form Submission 1.0. Let's get you up to speed on what this means and how to protect yourself.

🔍 TL;DR Summary

A critical SQL injection vulnerability has been discovered in Exam Form Submission 1.0. An attacker can remotely execute arbitrary SQL commands by manipulating the 'ID' parameter in the /admin/delete_s7.php file. This could lead to data breaches, modification, or complete system compromise. Proof-of-concept exploit code is publicly available.

🚨 Vulnerability Details

CVE ID: CVE-2025-8326
Description: A SQL injection vulnerability exists in Exam Form Submission 1.0, specifically in the /admin/delete_s7.php file. By manipulating the ID parameter, an attacker can execute arbitrary SQL queries.
CVSS Score: 7.3 (High)
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
CVSS Explanation: This vulnerability has a High severity score because it can be exploited remotely with low attack complexity and without requiring any privileges or user interaction. Successful exploitation can lead to limited impact on confidentiality, integrity, and availability.
Exploit Requirements: An attacker needs network access to the vulnerable application. No authentication is required.
Affected Vendor: code-projects
Affected Product: Exam Form Submission
Affected Version: 1.0
CWE: CWE-89 (SQL Injection) - CWE-89 occurs when an application incorporates user-controllable data into a SQL query without proper sanitization or validation. This allows an attacker to inject malicious SQL code, potentially compromising the database.

🧠 Exploitability & Real-World Risk

Given the availability of a public exploit, this vulnerability poses a significant risk. Attackers can easily craft malicious requests to extract sensitive data, modify existing records, or even gain administrative control over the application. The vulnerability is located in the /admin/ directory, suggesting that successful exploitation could lead to full system compromise if the attacker elevates their privileges.

🛠️ Recommendations

Immediate Patching: Apply the latest security patches or upgrade to a secure version of Exam Form Submission as soon as it becomes available.
Input Validation: Implement robust input validation and sanitization on all user-supplied data, especially the ID parameter in delete_s7.php.
Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection attacks. This ensures that user input is treated as data, not executable code.
Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts.
Least Privilege: Ensure that the database user account used by the application has only the necessary privileges. Avoid using the 'root' or 'administrator' account.

🧪 Technical Insight

The vulnerability stems from the lack of proper input sanitization in the delete_s7.php file. The ID parameter is directly incorporated into a SQL query without any validation or escaping. This allows an attacker to inject malicious SQL code that modifies the query's behavior, leading to unauthorized access and data manipulation.
