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.

Executive Summary

This vulnerability is a SQL injection flaw in DefaultFuction CRM 1.0.0. It exists in the /modules/customers/delete.php file where the 'ID' parameter is not properly sanitized before being used in a SQL query. Attackers can manipulate this parameter via a GET request to inject malicious SQL code, potentially accessing or altering database contents.

Detection Guidance

To detect this SQL injection vulnerability in DefaultFuction CRM 1.0.0, check if the 'id' parameter in /modules/customers/delete.php is vulnerable. Test by appending a single quote or SQL comment to the parameter in a GET request, e.g., /modules/customers/delete.php?id=1'. If the application returns an error or behaves unexpectedly, it may be vulnerable.

Impact Analysis

An attacker could exploit this to read, modify, or delete sensitive data in the database, such as customer records or credentials. They might also gain control over the system or disrupt services. Exploitation requires prior authentication but allows remote attacks.

Compliance Impact

This vulnerability could lead to unauthorized data access or breaches, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Immediately update DefaultFuction CRM to a patched version if available. If not, implement prepared statements with parameter binding for all SQL queries. Ensure strict input validation for the 'id' parameter. Restrict database user permissions to the minimum required. Conduct a security audit to identify other potential vulnerabilities.
