Directory traversal vulnerability in the Web Administration tool in IBM Tivoli Directory Server (ITDS) before 6.1.0.74-ISS-ISDS-IF0074, 6.2.x before 6.2.0.50-ISS-ISDS-IF0050, and 6.3.x before 6.3.0.43-ISS-ISDS-IF0043 and IBM Security Directory Server (ISDS) before 6.3.1.18-ISS-ISDS-IF0018 and 6.4.x before 6.4.0.9-ISS-ISDS-IF0009 allows remote attackers to read arbitrary files via a .. (dot dot) in a URL.

GSKit in IBM Tivoli Directory Server (ITDS) 6.0 before 6.0.0.73-ISS-ITDS-IF0073, 6.1 before 6.1.0.66-ISS-ITDS-IF0066, 6.2 before 6.2.0.42-ISS-ITDS-IF0042, and 6.3 before 6.3.0.35-ISS-ITDS-IF0035 and IBM Security Directory Server (ISDS) 6.3.1 before 6.3.1.9-ISS-ISDS-IF0009 does not properly restrict TLS state transitions, which makes it easier for remote attackers to conduct cipher-downgrade attacks to EXPORT_RSA ciphers via crafted TLS traffic, related to the "FREAK" issue, a different vulnerability than CVE-2015-0204.

Cross-site scripting (XSS) vulnerability in the Admin UI in IBM Tivoli Directory Server 6.1 before 6.1.0.64-ISS-ITDS-IF0064, 6.2 before 6.2.0.39-ISS-ITDS-FP0039, and 6.3 before 6.3.0.33-ISS-ITDS-IF0033, and IBM Security Directory Server 6.3.1 before 6.3.1.7-ISS-ISDS-IF0007, allows remote authenticated users to inject arbitrary web script or HTML via a crafted URL.

The default configuration of TLS in IBM Tivoli Directory Server (TDS) 6.3 and earlier supports the (1) NULL-MD5 and (2) NULL-SHA ciphers, which allows remote attackers to trigger unencrypted communication via the TLS Handshake Protocol.

IBM Tivoli Directory Server (TDS) 6.3 and earlier allows remote attackers to cause a denial of service (daemon crash) via a malformed LDAP paged search request.
