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.

Executive Summary

This vulnerability is a SQL injection issue found in the Class and Exam Timetabling System version 1.0, specifically in the /index2.php file. It occurs due to improper input validation of the 'password' parameter, which allows an attacker to inject malicious SQL queries remotely without needing authentication.

The vulnerability can be exploited using various SQL injection techniques such as boolean-based blind, error-based, and time-based blind SQL injection.

Impact Analysis

Exploiting this vulnerability can lead to unauthorized access to the database, resulting in data leakage, data tampering, potential system control by attackers, and disruption of services.

Detection Guidance

This SQL injection vulnerability in the /index2.php file can be detected by testing the 'password' parameter for SQL injection flaws using common techniques such as boolean-based blind, error-based, and time-based blind SQL injection.

You can use tools like sqlmap or manual curl commands to test the vulnerability. For example, sending crafted requests that inject SQL payloads into the 'password' parameter and observing the responses or delays can help identify the issue.

  • Example curl command to test for SQL injection: curl -G 'http://target/index2.php' --data-urlencode "password=' OR '1'='1"
  • Use sqlmap with: sqlmap -u "http://target/index2.php" --data="password=anything" --risk=3 --level=5 --batch
Mitigation Strategies

Immediate mitigation steps include implementing prepared statements to handle database queries safely and validating all input parameters, especially the 'password' parameter, to prevent malicious SQL injection.

Additionally, minimize database user permissions to limit the impact of a potential exploit and conduct regular security audits to detect and fix vulnerabilities early.

Compliance Impact

The SQL injection vulnerability in the Class and Exam Timetabling System allows unauthorized database access, data leakage, and tampering. Such unauthorized access and potential exposure of sensitive data can lead to non-compliance with data protection regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive information.

Failure to prevent such vulnerabilities may result in breaches of confidentiality, integrity, and availability of data, which are core requirements of these standards. Consequently, organizations using the affected software could face legal and regulatory consequences if the vulnerability is exploited.
