Overview

lemur is a Certificate management and orchestration service

Affected versions of this package are vulnerable to LDAP Injection via unsanitized input in the username field during the authentication process. An attacker can escalate privileges and gain unauthorized access to sensitive resources by injecting LDAP filter metacharacters into the login request. This is only exploitable if the attacker possesses valid LDAP credentials and LDAP authentication is enabled.
