{"id":"CVE-2020-1733","details":"A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with \"umask 77 && mkdir -p \u003cdir\u003e\"; this operation does not fail if the directory already exists and is owned by another user. An attacker could take advantage to gain control of the become user as the target directory can be retrieved by iterating '/proc/\u003cpid\u003e/cmdline'.","aliases":["GHSA-g4mq-6fp5-qwcf","PYSEC-2020-5"],"modified":"2026-08-07T11:31:11.096579638Z","published":"2020-03-11T19:15:13.030Z","related":["SUSE-SU-2020:2911-1","SUSE-SU-2020:3309-1","openSUSE-SU-2022:0081-1","openSUSE-SU-2024:10615-1","openSUSE-SU-2024:14244-1","openSUSE-SU-2024:14536-1","openSUSE-SU-2025:15605-1","openSUSE-SU-2025:15753-1","openSUSE-SU-2026:10944-1"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"last_affected":"3.3.4"},{"introduced":"3.3.5"},{"last_affected":"3.4.5"},{"introduced":"3.5.0"},{"last_affected":"3.5.5"},{"introduced":"3.6.0"},{"last_affected":"3.6.3"}],"source":"CPE_RANGE","vendor_product":"redhat:ansible_tower","cpes":["cpe:2.3:a:redhat:ansible_tower:*:*:*:*:*:*:*:*"]},{"cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"8.0"},{"last_affected":"8.0"},{"introduced":"10.0"},{"last_affected":"10.0"}],"source":"CPE_STRING","vendor_product":"debian:debian_linux"},{"source":"CPE_STRING","vendor_product":"fedoraproject:fedora","cpes":["cpe:2.3:o:fedoraproject:fedora:30:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:31:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:32:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"30"},{"last_affected":"30"},{"introduced":"31"},{"last_affected":"31"},{"introduced":"32"},{"last_affected":"32"}]},{"extracted_events":[{"introduced":"5.0"},{"last_affected":"5.0"}],"source":"CPE_STRING","vendor_product":"redhat:cloudforms_management_engine","cpes":["cpe:2.3:a:redhat:cloudforms_management_engine:5.0:*:*:*:*:*:*:*"]},{"cpes":["cpe:2.3:a:redhat:openstack:13:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"13"},{"last_affected":"13"}],"source":"CPE_STRING","vendor_product":"redhat:openstack"}]},"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DKPA4KC3OJSUFASUYMG66HKJE7ADNGFW/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MRRYUU5ZBLPBXCYG6CFP35D64NP2UB2S/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WQVOQD4VAIXXTVQAJKTN7NUGTJFE2PCB/"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2020/05/msg00005.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202006-11"},{"type":"ADVISORY","url":"https://www.debian.org/security/2021/dsa-4950"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1733"},{"type":"EVIDENCE","url":"https://github.com/ansible/ansible/issues/67791"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ansible/ansible","events":[{"introduced":"0"},{"last_affected":"8fd406ee8e3a14be72b3cbbfe91d03fe35952f95"},{"introduced":"2611867fd1dc387ceaa0ffb8ce0f030aafc2a859"},{"fixed":"d28e4b63c7b70acbaf0a1fedd53c91b6686574a0"},{"introduced":"24325a05dfb9104d6d4ec8b488b89e07c2e6d376"},{"last_affected":"9388be4269bdf83406bfa9245142de8b7dc8cfbc"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:redhat:ansible:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"2.7.16"},{"introduced":"2.8.0"},{"fixed":"2.8.8"},{"introduced":"2.9.0"},{"last_affected":"2.9.5"}]}}],"versions":["v2.9.5","v2.9.4","v2.9.3","v2.7.16","v2.9.2","v2.9.1","v2.8.7","v2.7.15","v2.9.0","v2.8.6","v2.7.14","v2.8.5","v2.7.13","v2.8.4","v2.8.3","v2.7.12","v2.8.2","v2.8.1","v2.7.11","v2.8.0","v2.7.10","v2.7.9","v2.7.8","v2.7.7","v2.7.6","v2.7.5","v2.7.4","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.7.0rc4","v2.7.0rc3","v2.7.0rc2","v2.7.0rc1","v2.7.0b1","v2.7.0.a1","v2.6.0a1","v2.0.0-0.5.beta3","v2.0.0-0.4.beta2","v2.0.0-0.3.beta1","v2.0.0-0.2.alpha2","v2.0.0-0.1.alpha1","v1.6.0","v1.4.0","v1.2","v1.1","v1.0","0.7","0.3","0.0.1","0.01"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-1733.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:L"}]}
