Name of the Vulnerable Software and Affected Versions Kanboard versions 1.2.48 and below

Description Kanboard is project management software focused on Kanban methodology. Versions 1.2.48 and below contain an LDAP Injection issue within the LDAP authentication mechanism. User-supplied input is directly incorporated into LDAP search filters without sufficient sanitization.
