IBM WebSphere Application Server 7.0, 8.0, 8.5, 9.0 and Liberty 17.0.0.3 through 21.0.0.9 could allow a remote user to enumerate usernames due to a difference of responses from valid and invalid login attempts. IBM X-Force ID: 205202.

Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
