Blind SQL Injection in Krayin CRM Leads DataGrid

Publication date: 2026-08-03

Last updated on: 2026-08-03

Assigner: VulnCheck

Description
Krayin CRM before 2.2.4 contains a blind SQL injection vulnerability in the leads DataGrid that allows authenticated users with leads access to inject arbitrary SQL into a HAVING clause by manipulating the rotten_lead[in] query parameter, which is concatenated without parameterized binding directly into a havingRaw() call in LeadDataGrid.php. Attackers can exploit this flaw using time-based and boolean-based blind injection techniques to extract the entire database contents, including user credential hashes, CRM records, and application configuration data.

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

Krayin CRM before version 2.2.4 has a blind SQL injection flaw in the leads DataGrid feature. Authenticated users with leads access can inject malicious SQL into a HAVING clause by manipulating the rotten_lead[in] query parameter. This parameter is directly concatenated into a havingRaw() call without proper parameterized binding, allowing attackers to extract sensitive data like user credentials and CRM records using time-based or boolean-based blind injection techniques.

Detection Guidance

To detect this vulnerability, inspect the Krayin CRM application for the presence of the leads DataGrid feature. Check if the application uses the rotten_lead[in] query parameter in LeadDataGrid.php without parameterized binding. Monitor SQL query logs for unusual HAVING clause manipulations or time-based/boolean-based blind injection attempts.

Impact Analysis

If you use Krayin CRM versions before 2.2.4, an attacker with leads access could steal your entire database, including user passwords, CRM records, and application settings. This could lead to data breaches, unauthorized access to sensitive information, and potential misuse of extracted data for further attacks.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA due to unauthorized data access and potential exposure of personal or health information. GDPR requires protection of personal data, while HIPAA mandates safeguards for health data. A breach could result in legal penalties, fines, and reputational damage for non-compliance.

Mitigation Strategies

Immediately upgrade Krayin CRM to version 2.2.4 or later to patch the vulnerability. If upgrading is not possible, restrict access to the leads DataGrid feature for authenticated users and implement input validation to sanitize the rotten_lead[in] parameter. Review database permissions to limit exposure of sensitive data.
