Description
Incorrect LDAP ACLs in ucs-school-ldap-acls-master in UCS@school before 4.4v5-errata allow remote teachers, staff, and school administrators to read LDAP password hashes (sambaNTPassword, krb5Key, sambaPasswordHistory, and pwhistory) via LDAP search requests. For example, a teacher can gain administrator access via an NTLM hash.
