Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Improper input validation
EUVDB-ID: #VU6639
Risk: Medium
CVSSv4.0: 7.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2016-9587,CVE-2017-7466
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation when processing responses, send by clients to Ansible server. A remote client can send a specially crafted response and execute arbitrary code on the target system.
