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.
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 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.
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.
