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.

Mitigation Strategies

Immediate mitigation steps include implementing prepared statements to handle database queries securely and applying strict input validation on the 'sy' parameter to prevent malicious input.

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

Executive Summary

The CVE-2026-13487 vulnerability affects the Class and Exam Timetabling System Project V1.0, specifically in the `/archive.php` file.

It is an SQL injection flaw caused by improper input validation of the 'sy' parameter, which allows attackers to inject malicious SQL queries without needing authentication.

This vulnerability can be exploited remotely and has been confirmed through testing using boolean-based blind and error-based SQL injection techniques.

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized access to the database, allowing attackers to tamper with data and leak sensitive information.

Attackers may also gain control over the system and cause service disruptions.

Detection Guidance

The vulnerability can be detected by testing the 'sy' parameter in the /archive.php file for SQL injection flaws. This can be done using boolean-based blind and error-based SQL injection payloads to observe the system's response.

  • Use tools like sqlmap to automate detection, targeting the 'sy' parameter in the URL or POST data.
  • Example command with sqlmap: sqlmap -u "http://targetsite/archive.php?sy=1" --batch --level=5 --risk=3
  • Manually test by injecting SQL payloads such as ' OR '1'='1' -- into the 'sy' parameter and observe if the response changes or errors occur.
Compliance Impact

The SQL injection vulnerability in the Class and Exam Timetabling System allows unauthorized database access, data tampering, and sensitive information leakage. Such impacts can lead to violations of data protection regulations like GDPR and HIPAA, which require the protection of personal and sensitive data from unauthorized access and breaches.

Failure to address this vulnerability could result in non-compliance with these standards due to compromised data integrity and confidentiality, potentially leading to legal and financial consequences.
