Description:
Multiple vulnerabilities and security issues have been reported in Secure Elements Class 5 AVR, which can be exploited by malicious people to disclose potentially sensitive information, bypass certain security restrictions, spoof the contents of messages, cause a DoS (Denial of Service) and potentially to compromise a vulnerable system.
1) Missing authentication of received registration messages can be exploited to cause a DoS on the server via a large number of forged client registration messages sent to the server.
2) A pathname validation error in the server when downloading updates can be exploited to overwrite arbitrary files on the server with root privileges.
3) A boundary error within the handling of the size of EM_SET_CE_PARAMETER messages can be exploited to view the contents of process memory on a vulnerable client.
4) Missing validation of the source address of messages can potentially be exploited to spoof client messages sent to the server.
5) Encryption of messages exchanged with a client is not enforced by the server. This can potentially disclose sensitive information within the messages.
6) The client uses the same RSA key for all installations. This can potentially be exploited to decrypt communications between the systems.
7) The server does not properly validate the peer certificate when downloading updates. This can potentially be exploited to distribute malicious updates to the clients.
8) An error in enforcing access controls on certain console operations can be exploited to gain unauthorised administrative access to a server.
9) A hard-coded user ID and password exists on the server. This can potentially be exploited to gain unauthorised access to the server.
10) An error in enforcing the integrity of message digests in received messages by both the client and the server can be exploited to replay and modify messages without requiring knowledge of any keys.
11) The client is identified by a CEID property which is predictable. This may allow an attacker to guess the unique identifier of a protected asset.
12) Missing validation of the pathname supplied in received messages can be exploited to overwrite arbitrary files on a vulnerable client with root privileges.
13) Missing validation of the source address of received messages can potentially be exploited to execute arbitrary code with root privileges on a vulnerable client.
14) An error within the authentication of "session start" messages by the server can be exploited to cause the server to initiate TCP connections to arbitrary destinations. This can potentially cause a DoS on both the server and the specified target.
15) The client does not validate the target CEID in a received message. This may facilitate further attacks without the need to guess the true CEID of a victim asset.
The vulnerabilities and security issues have been reported in version prior to 2.8.1.
