Description

This security bulletin contains information about 3 vulnerabilities.


1) Path traversal (CVE-ID: CVE-2018-0323)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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


The vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.

The weakness exists in the web management interface due to insufficient validation of web request parameters. A remote attacker who has access to the web management interface can send a specially crafted web request, trigger path traversal and gain access to potentially sensitive information.


2) Command injection (CVE-ID: CVE-2018-0324)

CWE-ID: CWE-77 - Command injection

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


The vulnerability allows a local authenticated attacker to execute arbitrary commands on the target system.

The weakness exists in the CLI parser due to insufficient input validation of command parameters. A local attacker can invoke a vulnerable CLI command with specially crafted parameters and execute arbitrary commands with a non-root user account on the underlying Linux operating system.


3) Improper input validation (CVE-ID: CVE-2018-0279)

CWE-ID: CWE-20 - Improper input validation

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


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

The weakness exists in the Secure Copy Protocol (SCP) server due to improper input validation of command arguments. A rmote attacker can use specially crafted arguments when opening a connection to the target device and gain shell access with a non-root user account to the underlying Linux operating system.
