Description

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, a SQL Injection vulnerability exists in the SuiteCRM authentication mechanisms when directory support is enabled. The application fails to properly sanitize the user-supplied username before using it in a local database query. An attacker with valid, low-privilege directory credentials can exploit this to execute arbitrary SQL commands, leading to complete privilege escalation (e.g., logging in as the CRM Administrator). Versions 7.15.1 and 8.9.3 patch the issue.

Affected products

SuiteCRM: before 7.15.1; from 8.0.0 before 8.9.3 — fixed in 7.15.1, 8.9.3

How to fix

Upgrade to a fixed version: SuiteCRM 7.15.1, 8.9.3. Check the vendor advisory for mitigations.
