PHP SQL injection in Student Web Portal (CVE-2026-3744)

Overview

A significant security vulnerability, identified as CVE-2026-3744, has been discovered in the code-projects Student Web Portal version 1.0. This flaw is a SQL Injection vulnerability that exists within the user registration functionality. Specifically, it resides in the valreg_passwdation function of the signup.php file, where the reg_passwd argument can be maliciously manipulated. Attackers can exploit this vulnerability remotely without requiring prior access to the target system.

Vulnerability Details

In simple terms, this vulnerability allows an attacker to inject malicious SQL code through the password field during the user sign-up process. The web portal’s software does not properly check or “sanitize” this input. Consequently, an attacker can craft a special password that, when processed by the system, tricks the database into executing unauthorized commands. This can lead to the theft, modification, or deletion of sensitive data stored in the portal’s database, such as student records, login credentials, and personal information. A public exploit is available, making attacks more likely.

Impact and Risk

With a high severity CVSS score of 7.3, this vulnerability poses a serious risk. Successful exploitation could result in a full compromise of the application’s database. Attackers could:

• Steal sensitive student and administrator data.
• Create unauthorized administrative accounts.
• Tamper with or destroy academic records.
• Use the compromised system as a foothold for further attacks within the network. Given the public disclosure of the exploit, unpatched systems are actively vulnerable to attack. Organizations should be aware that such breaches often lead to regulatory fines and loss of trust; you can review the consequences of similar incidents in our breach reports.

Remediation and Mitigation

Immediate action is required to secure affected systems.

1. Patch or Update: As a first priority, contact the software vendor (code-projects) to obtain a patched version of the Student Web Portal. If an official patch is not available, consider discontinuing use of this version.
2. Apply Input Validation: If immediate patching is not possible, implement strict input validation and parameterized queries on the signup.php file to neutralize SQL injection attempts. This should be performed by a qualified developer.
3. Network Controls: Restrict network access to the web portal to only necessary users and IP ranges, if feasible.
4. Monitoring: Review database and web application logs for any suspicious SQL query patterns or unexpected administrative activity.
