{"id":"GHSA-m85c-9mf8-m2m6","summary":"Unsafe deserialization in confire","details":"An exploitable vulnerability exists in the YAML parsing functionality in config.py in Confire 0.2.0. Due to the user-specific configuration being loaded from \"~/.confire.yaml\" using the yaml.load function, a YAML parser can execute arbitrary Python commands resulting in command execution. An attacker can insert Python into loaded YAML to trigger this vulnerability.","aliases":["CVE-2017-16763","PYSEC-2017-78"],"modified":"2025-02-15T05:30:25.681979Z","published":"2018-07-18T18:28:26Z","database_specific":{"cwe_ids":[],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2020-06-16T21:45:21Z","nvd_published_at":null},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2017-16763"},{"type":"WEB","url":"https://github.com/bbengfort/confire/issues/24"},{"type":"WEB","url":"https://github.com/bbengfort/confire/commit/8cc86a5ec2327e070f1d576d61bbaadf861597ea"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-m85c-9mf8-m2m6"},{"type":"PACKAGE","url":"https://github.com/bbengfort/confire"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/confire/PYSEC-2017-78.yaml"},{"type":"WEB","url":"https://joel-malwarebenchmark.github.io/blog/2017/11/12/cve-2017-16763-configure-loaded-through-confire"}],"affected":[{"package":{"name":"confire","ecosystem":"PyPI","purl":"pkg:pypi/confire"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"0.2.0"}]}],"versions":["0.1.0","0.1.1","0.2.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2018/07/GHSA-m85c-9mf8-m2m6/GHSA-m85c-9mf8-m2m6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
