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 flaw found in the Class and Exam Timetabling System version 1.0, specifically in the /archive4.php file. It occurs due to improper input validation of the 'sy' parameter, which allows attackers to inject malicious SQL queries remotely without needing authentication.

This means an attacker can manipulate the database queries executed by the system, potentially gaining unauthorized access to sensitive data or altering the database.

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized database access, data manipulation, and exposure of sensitive information. Attackers may tamper with data or disrupt services, potentially compromising the entire system.

Detection Guidance

This vulnerability can be detected by testing the 'sy' parameter in the /archive4.php file for SQL injection flaws. You can attempt to inject SQL payloads into the 'sy' parameter and observe if the system behaves unexpectedly or returns database errors.

  • Use curl or similar tools to send crafted requests to the vulnerable endpoint, for example: curl "http://targetsite/archive4.php?sy=' OR '1'='1"
  • Use automated SQL injection detection tools such as sqlmap targeting the 'sy' parameter: sqlmap -u "http://targetsite/archive4.php?sy=1" --param=sy

Monitoring network traffic for unusual or suspicious requests targeting /archive4.php with SQL injection patterns can also help detect exploitation attempts.

Mitigation Strategies

Immediate mitigation steps include implementing prepared statements or parameterized queries to prevent SQL injection via the 'sy' parameter.

  • Apply strict input validation and sanitization on the 'sy' parameter to ensure only expected input is processed.
  • Minimize database user permissions to limit the impact of a potential SQL injection attack.
  • Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.

If possible, update or patch the system once an official fix is released.

Compliance Impact

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

Exploitation of this vulnerability could result in data tampering and service disruption, further violating integrity and availability requirements mandated by these standards.
