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.
The product constructs all or part of an LDAP query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended LDAP query when it is sent to a downstream component.
