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 in Yot CMS up to version 3.3.1. The issue occurs in the Login function of global.php where the yot3_user and yot3_pass cookies are used to authenticate users without proper sanitization. Attackers can inject malicious SQL code via these cookies to manipulate database queries, potentially gaining unauthorized administrative access.

Detection Guidance

To detect this SQL injection vulnerability in Yot CMS, monitor HTTP requests for the yot3_user and yot3_pass cookies. Check if the application processes these cookies without proper input validation. Use tools like SQLmap to test for SQL injection by sending crafted payloads in these cookies. Inspect server logs for unusual SQL queries or errors indicating injection attempts.

Impact Analysis

This vulnerability allows remote attackers to forge administrator sessions without valid credentials. By exploiting the SQL injection, attackers can gain full administrative privileges, access sensitive data, and perform unauthorized actions on the affected system. The exploit is publicly available and can be used over HTTP.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements under GDPR and HIPAA. Organizations using the affected Yot CMS version may face compliance breaches, legal penalties, and reputational damage due to potential data exposure or unauthorized modifications.

Mitigation Strategies

Immediately upgrade Yot CMS to the latest version beyond 3.3.1. Disable cookie-based auto-login if possible. Implement strict input validation for all cookie values. Use prepared statements for all SQL queries. Remove or disable the vulnerable login() function in global.php. Monitor network traffic for suspicious activity targeting these cookies.
