Affected devices are vulnerable to path traversal attacks. This could allow a privileged local attacker to restore backups that are outside the backup folder.
Affected devices do not properly assign permissions to critical ressources. This could allow a non-privileged local attacker to interact with the backupmanager service.
Affected devices do not properly validate incoming Profinet packets. An unauthenticated remote attacker can exploit this flaw by sending a specially crafted malicious packet, which leads to a crash of the dcpd process.

Affected devices do not properly validate incoming Profinet packets. An unauthenticated remote attacker can exploit this flaw by sending a specially crafted malicious packet, which leads to a crash of the dcpd process.
Affected devices do not properly handle multiple incoming Profinet packets received in rapid succession. An unauthenticated remote attacker can exploit this flaw by sending multiple packets in a very short time frame, which leads to a crash of the dcpd process.

Affected devices are vulnerable to a stack-based buffer overflow. This could allow a non-privileged local attacker to execute arbitrary code on the device or to cause a denial of service condition.
Affected devices are vulnerable to a stack-based buffer overflow. This could allow a non-privileged local attacker to execute arbitrary code on the device or to cause a denial of service condition.
Affected devices are vulnerable to an authentication bypass. This could allow a non-privileged local attacker to bypass the authentication of the SINEMA Remote Connect Edge Client, and to read and modify the configuration parameters.

Affected devices do not properly sanitize configuration parameters. This could allow a non-privileged local attacker to execute root commands on the device.
Affected devices do transmit sensitive information in cleartext. This could allow a privileged local attacker to retrieve this sensitive information.
