Secure Elements Class 5 AVR client (aka C5 EVM) before 2.8.1 does not validate the CEID of an incoming message, which allows remote attackers to send messages to a protected asset without knowing the proper CEID.

Secure Elements Class 5 AVR (aka C5 EVM) before 2.8.1 do not validate the source address of a message, which allows remote attackers to (1) execute arbitrary code on a client or (2) forge messages to the server.

Secure Elements Class 5 AVR client (aka C5 EVM) before 2.8.1 allows remote attackers to read portions of process memory via a modified size for (1) EM_GET_CE_PARAMETER and (2) EM_SET_CE_PARAMETER messages, which leads to a buffer overflow (probably an over-read).

Secure Elements Class 5 AVR server (aka C5 EVM) before 2.8.1 allows remote attackers to cause a denial of service via forged "session start" messages that cause AVR to connect to arbitrary hosts.

Secure Elements Class 5 AVR server and client (aka C5 EVM) before 2.8.1 send messages in cleartext, which allows remote attackers to read sensitive vulnerability information.

Secure Elements Class 5 AVR (aka C5 EVM) before 2.8.1 uses the same invariant RSA key for all installations, which allows remote attackers with the key to decrypt communications.

Unspecified vulnerability in Secure Elements Class 5 AVR client and server (aka C5 EVM) before 2.8.1 allows authenticated attackers to overwrite arbitrary files (1) on a server during an update or (2) on a client via modified pathnames, possibly due to a directory traversal issue.

Secure Elements Class 5 AVR server (aka C5 EVM) before 2.8.1 uses a hard-coded user ID and password, which allows remote attackers to gain access to the server.

Secure Elements Class 5 AVR server (aka C5 EVM) before 2.8.1 allows remote attackers to cause an unspecified denial of service via a large number of forged client registration messages.

Cross-site scripting (XSS) vulnerability in viewCart.asp in CartWIZ allows remote attackers to inject arbitrary web script or HTML via the message parameter.
