The Administration Console in Secure Elements Class 5 AVR (aka C5 EVM) before 2.8.1 does not enforce access control, which allows remote attackers to gain access to servers via the console.

Secure Elements Class 5 AVR client (aka C5 EVM) before 2.8.1 generates predictable CEIDs, which allows remote attackers to determine the CEID of a protected asset, which can be used in other attacks against AVR.

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

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.
