A lack of authentication, in CA Unified Infrastructure Management 8.5.1, 8.5, and 8.4.7, allows remote attackers to conduct a variety of attacks, including file reading/writing.
The get_sessions servlet in CA Unified Infrastructure Management (formerly CA Nimsoft Monitor) before 8.5 and CA Unified Infrastructure Management Snap (formerly CA Nimsoft Monitor Snap) allows remote attackers to obtain active session ids and consequently bypass authentication or gain privileges via unspecified vectors.
