    Indirect LDAP injection via the ldap_id attribute of a user when checking if it exists

    Tuleap does not sanitize properly the search filter built from the ldap_id attribute of a user during the daily synchronization when checking it the user still exist. This issue is related to request #24149, the initial fix was incomplete.

    Impact

    A malicious user could force accounts to be suspended or take over another account by forcing the update of the ldap_uid attribute. Note that the malicious user either need to have site administrator capability on the Tuleap instance or be an LDAP operator with the capability to create/modify account.
