Security Bulletin

This security bulletin contains information about 8 vulnerabilities.

1) Code Injection

EUVDB-ID: #VU29017

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-10684

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation when using "ansible_facts" as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the "ansible_facts" after the clean. A local user can alter the "ansible_facts", such as "ansible_hosts", "users" and any other key data which would lead into privilege escalation or code injection

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

Mitigation

Install updates from vendor's website.
