Smart eVision has an improper privilege management vulnerability. A remote attacker with general user privilege can exploit this vulnerability to escalate to administrator privilege, and then perform arbitrary system command or disrupt service.
CVE-2022-39031
Smart eVision has insufficient authorization for task acquisition function. An unauthorized remote attacker can exploit this vulnerability to acquire the Session IDs of other general users only.
CVE-2022-39030
smart eVision has inadequate authorization for system information query function. An unauthenticated remote attacker, who is not explicitly authorized to access the information, can access sensitive information.
CVE-2022-3903
An incorrect read request flaw was found in the Infrared Transceiver USB driver in the Linux kernel. This issue occurs when a user attaches a malicious USB device. A local user could use this flaw to starve the resources, causing denial of service or potentially crashing the system.
CVE-2022-39029
Smart eVision has inadequate authorization for the database query function. A remote attacker with general user privilege, who is not explicitly authorized to access the information, can access sensitive information.
CVE-2022-39028
telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a “telnet/tcp server failing (looping), service terminated” error. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.
