Description

This security bulletin contains information about 2 vulnerabilities.


1) OS Command Injection (CVE-ID: CVE-2019-14905)

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

CVSSv4: CVSS:4.0/AV:L/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 local user to execute arbitrary shell commands on the target system.

The vulnerability exists due to incorrect validation of filenames within the nxos_file_copy module when copying files to a flash or bootflash on NXOS devices using the remote_file parameter. A local user or malicious code can abuse this functionality to inject and execute arbitrary OS commands on the system with elevated privileges.



2) OS Command Injection (CVE-ID: CVE-2019-14904)

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

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:Green


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

The vulnerability exists due to improper input validation when processing zone names within the solaris_zone module. A remote uuser can provide a specially crafted zone name as a parameter to the os.system() call and execute arbitrary OS commands on the target system.
