Technical description

EspoCRM is an open source customer relationship management application. From 8.1.0 until 9.3.8, an authenticated non-administrator can submit a crafted where parameter to the GET entity streamAttachments endpoint because that query path permits complex expressions. Boolean-based blind SQL injection can extract arbitrary database information, including active administrator session tokens, and can enable full privilege escalation. This issue is fixed in version 9.3.8.

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.
