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 Construction Management System version 1.0, specifically in the '/del1.php' file within the 'toolname' POST parameter.

The application does not properly sanitize or validate the 'toolname' input before using it in SQL queries, allowing authenticated attackers to inject malicious SQL code.

Exploitation requires valid user credentials and can be performed remotely.

Attackers can manipulate SQL queries to gain unauthorized database access, leak sensitive data, tamper with data, gain full system control, or disrupt services.

Impact Analysis

This vulnerability can have serious impacts including unauthorized access to your database and sensitive information.

  • Leakage of sensitive data.
  • Tampering or modification of data.
  • Potential full control over the affected system by attackers.
  • Disruption of services, affecting business continuity.
Detection Guidance

This SQL injection vulnerability in the '/del1.php' file can be detected by testing the 'toolname' POST parameter for injection flaws.

  • Use boolean-based blind injection payloads such as: toolname=1' RLIKE (SELECT (CASE WHEN (2699=2699) THEN 1 ELSE 0x28 END))--
  • Use error-based injection payloads exploiting MySQL functions, for example: toolname=1' AND GTID_SUBSET(CONCAT(0x71766b6a71,(SELECT (ELT(6267=6267,1))),0x7170717171),6267)--
  • Use time-based blind injection payloads to cause query delays, such as: toolname=1' AND (SELECT 2028 FROM (SELECT(SLEEP(5)))lGFV)--

Testing can also be automated using tools like sqlmap targeting the vulnerable endpoint with appropriate parameters.

Mitigation Strategies

Immediate mitigation steps include:

  • Implement prepared statements with parameter binding to separate SQL code from user input.
  • Enforce strict input validation and filtering to ensure inputs conform to expected formats.
  • Minimize database user permissions by avoiding use of high-privilege accounts for routine operations.
  • Conduct regular security audits of code and systems to detect and address vulnerabilities promptly.
Compliance Impact

The SQL injection vulnerability in the Construction Management System 1.0 can lead to unauthorized database access, sensitive data leakage, data tampering, and full system control by attackers.

Such impacts can compromise the confidentiality, integrity, and availability of sensitive data, which are critical requirements under common standards and regulations like GDPR and HIPAA.

Therefore, exploitation of this vulnerability may result in non-compliance with these regulations due to potential data breaches and failure to protect personal or sensitive information.
