{"id":"CVE-2017-16618","details":"An exploitable vulnerability exists in the YAML loading functionality of util.py in OwlMixin before 2.0.0a12. A \"Load YAML\" string or file (aka load_yaml or load_yamlf) can execute arbitrary Python commands resulting in command execution because load is used where safe_load should have been used. An attacker can insert Python into loaded YAML to trigger this vulnerability.","aliases":["GHSA-ccmq-qvcp-5mrm","PYSEC-2017-22"],"modified":"2026-07-08T05:51:30.008413031Z","published":"2017-11-08T03:29:00.277Z","database_specific":{"unresolved_ranges":[{"source":"CPE_STRING","vendor_product":"owlmixin_project:owlmixin","cpes":["cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha10:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha11:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha1:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha2:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha3:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha4:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha5:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha6:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha7:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha8:*:*:*:*:*:*","cpe:2.3:a:owlmixin_project:owlmixin:2.0.0:alpha9:*:*:*:*:*:*"],"extracted_events":[{"introduced":"2.0.0-alpha1"},{"last_affected":"2.0.0-alpha1"},{"introduced":"2.0.0-alpha10"},{"last_affected":"2.0.0-alpha10"},{"introduced":"2.0.0-alpha11"},{"last_affected":"2.0.0-alpha11"},{"introduced":"2.0.0-alpha2"},{"last_affected":"2.0.0-alpha2"},{"introduced":"2.0.0-alpha3"},{"last_affected":"2.0.0-alpha3"},{"introduced":"2.0.0-alpha4"},{"last_affected":"2.0.0-alpha4"},{"introduced":"2.0.0-alpha5"},{"last_affected":"2.0.0-alpha5"},{"introduced":"2.0.0-alpha6"},{"last_affected":"2.0.0-alpha6"},{"introduced":"2.0.0-alpha7"},{"last_affected":"2.0.0-alpha7"},{"introduced":"2.0.0-alpha8"},{"last_affected":"2.0.0-alpha8"},{"introduced":"2.0.0-alpha9"},{"last_affected":"2.0.0-alpha9"}]}]},"references":[{"type":"FIX","url":"https://github.com/tadashi-aikawa/owlmixin/commit/5d0575303f6df869a515ced4285f24ba721e0d4e"},{"type":"FIX","url":"https://github.com/tadashi-aikawa/owlmixin/issues/12"},{"type":"EVIDENCE","url":"https://joel-malwarebenchmark.github.io/blog/2017/11/08/cve-2017-16618-convert-through-owlmixin/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tadashi-aikawa/owlmixin","events":[{"introduced":"0"},{"fixed":"de81bf86fd4584f49cdd4eb67012e85d2aaed771"},{"fixed":"5d0575303f6df869a515ced4285f24ba721e0d4e"}],"database_specific":{"cpe":"cpe:2.3:a:owlmixin_project:owlmixin:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.0.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["2.0.0a12","2.0.0a11","2.0.0a10","2.0.0a9","2.0.0a8","2.0.0a7","2.0.0a6","2.0.0a5","2.0.0a4","2.0.0a3","2.0.0a2","1.2.0","1.1.0","1.0.0","1.0.0rc16","1.0.0rc15","1.0.0rc14","1.0.0rc13","1.0.0rc12","1.0.0rc11","1.0.0rc10","1.0.0rc9","1.0.0rc8","1.0.0rc7","1.0.0rc6","1.0.0rc5","1.0.0rc4","1.0.0rc3","1.0.0rc2","1.0.0rc1","1.0.0b7","1.0.0b6","1.0.0b5","1.0.0b4","1.0.0b3","1.0.0b2","1.0.0b1","1.0.0a2","1.0.0a1","0.8.0","0.7.1","0.7.0","0.6.0","0.5.1","0.5.0","0.4.0","0.3.1","0.3.0","0.2.1","0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-16618.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
