E5572-855 with versions earlier than 8.0.1.3(H335SP1C233) has an improper authentication vulnerability. The device does not perform a sufficient authentication when doing certain operations, successful exploit could allow an attacker to cause the device to reboot after launch a man in the middle attack.
The AAA functionality in the IPv4 SSL VPN implementations on Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services Module (ASASM) in Cisco Catalyst 6500 series devices, with software 8.2 before 8.2(5.30) and 8.3 before 8.3(2.34) allows remote attackers to cause a denial of service (device reload) via a crafted authentication response, aka Bug ID CSCtz04566.
Secure Shell (SSH) 2 in Cisco IOS 12.0 through 12.3 allows remote attackers to cause a denial of service (device reload) (1) via a username that contains a domain name when using a TACACS+ server to authenticate, (2) when a new SSH session is in the login phase and a currently logged in user issues a send command, or (3) when IOS is logging messages and an SSH session is terminated while the server is sending data.
The Location Bandwidth Manager (LBM) Intracluster-communication feature in Cisco Unified Communications Manager (CUCM) 9.x before 9.1(1) does not require authentication from the remote LBM Hub node, which allows remote attackers to conduct cache-poisoning attacks against transaction records, and cause a denial of service (bandwidth-pool consumption and call outage), via unspecified vectors, aka Bug ID CSCub28920.
The American Power Conversion (APC) AP7932 0u 30amp Switched Rack Power Distribution Unit (PDU), with rpdu 3.5.5 and aos 3.5.6, allows remote attackers to bypass authentication and obtain login access by making a login attempt while a different client is logged in, and then resubmitting the login attempt once the other client exits.
