Description

This security bulletin contains information about 6 vulnerabilities.


1) Improper authentication (CVE-ID: CVE-2017-12088)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the Ethernet functionality due to improper authentication. A remote attacker can submit a specially crafted packet and cause the service to crash.

2) Improper authentication (CVE-ID: CVE-2017-12089)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the program download functionality due to improper authentication. A remote attacker can submit a specially crafted packet that does not indicate the download is complete to the controller during the standard download process and cause the service to crash.

3) Improper authentication (CVE-ID: CVE-2017-12090)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the processing of snmp-set commands due to improper authentication. A remote attacker can submit a specially crafted snmp-set request without associated SNMP-set commands for firmware flashing and cause the service to crash.

4) Improper authentication (CVE-ID: N/A)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists due to improper authentication. A remote attacker can submit a specially crafted packet and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

5) Improper authentication (CVE-ID: CVE-2017-12092)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to write arbitrary files on the target system.

The weakness exists in the memory module functionality due to improper authentication. A remote attacker can submit a specially crafted packet and write arbitrary files.

6) Improper authentication (CVE-ID: CVE-2017-12093)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the session communication functionality due to improper authentication. A remote attacker can submit a specially crafted stream of packets that trigger a flood of the session resource pool and cause the service to crash.
