CVSSv3.1: 6.6 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2019-5157

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Exploit availability: No

The vulnerability allows a remote user to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation within the Cloud Connectivity functionality in the "TimeoutUnconfirmed" parameter value contained in the Firmware Update command. A remote administrator can execute arbitrary OS commands on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

25) Buffer overflow

EUVDB-ID: #VU26255

Risk: High

CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:U/RC:C]

CVE-ID: CVE-2019-5166

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

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

The vulnerability exists due to a boundary error in the iocheckd service "I/O-Check" functionality. A remote authenticated attacker can use a specially crafted XML cache file, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

26) Double Free

EUVDB-ID: #VU26254

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:U/RC:C]

CVE-ID: CVE-2019-5184

CWE-ID: CWE-415 - Double Free

Exploit availability: No

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the iocheckd service "I/O-Check" functionality. A remote authenticated attacker can use a specially crafted XML cache file, trigger double free error and cause a denial of service condition on the target system, leading to remote code execution.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
