Description

EspoCRM is an Open Source CRM (Customer Relationship Management) software. EspoCRM versions 9.1.6 and earlier are vulnerable to blind LDAP Injection when LDAP authentication is enabled. A remote, unauthenticated attacker can manipulate LDAP queries by injecting crafted input containing wildcard characters (e.g., *). This may allow the attacker to bypass authentication controls, enumerate valid usernames, or retrieve sensitive directory information depending on the LDAP server configuration. This was fixed in version 9.1.7.

Affected products

• espocrm: before 9.1.7 — fixed in 9.1.7

How to fix

Upgrade to a fixed version: espocrm 9.1.7. Check the vendor advisory for mitigations.
