Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |

Can you explain this vulnerability to me?
CVE-2026-3744 is a critical SQL injection vulnerability found in the Student Web Portal version 1.0, specifically in the function valreg_passwdation within the signup.php file.
The vulnerability arises from improper handling and insufficient validation of the reg_passwd input parameter, which allows an attacker to inject malicious SQL code.
This flaw enables attackers to manipulate SQL queries executed by the application, potentially leading to unauthorized database access.
The attack can be initiated remotely without any authentication, making exploitation straightforward and easy.
How can this vulnerability impact me? :
Exploitation of this vulnerability allows attackers to gain unauthorized access to the database.
- Attackers can retrieve sensitive information stored in the database.
- They can modify or delete data, compromising data integrity.
- The vulnerability can lead to data leakage, unauthorized data manipulation, and potentially full system compromise or service disruption.
Overall, this can severely impact the confidentiality, integrity, and availability of the affected system.
