Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
