{"id":"GHSA-6v56-cpg6-3rpx","summary":"Mercurial vulnerable to arbitrary code injection","details":"In Mercurial before 4.4.1, it is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a `.git/hooks/post-update` script checked into the repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically.","aliases":["CVE-2017-17458","PYSEC-2017-90"],"modified":"2024-09-25T18:03:31.790861Z","published":"2022-05-13T01:24:56Z","database_specific":{"cwe_ids":["CWE-78"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2024-05-01T17:02:42Z","nvd_published_at":"2017-12-07T18:29:00Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2017-17458"},{"type":"WEB","url":"https://bz.mercurial-scm.org/show_bug.cgi?id=5730"},{"type":"WEB","url":"https://confluence.atlassian.com/sourcetreekb/sourcetree-security-advisory-2018-01-24-942834324.html"},{"type":"PACKAGE","url":"https://github.com/dscho/hg"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/mercurial/PYSEC-2017-90.yaml"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2017/12/msg00027.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2018/07/msg00005.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2018/07/msg00041.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/07/msg00032.html"},{"type":"WEB","url":"https://web.archive.org/web/20200227132808/http://www.securityfocus.com/bid/102926"},{"type":"WEB","url":"https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-November/107333.html"},{"type":"WEB","url":"https://www.mercurial-scm.org/wiki/WhatsNew#Mercurial_4.4.1_.282017-11-07.29"}],"affected":[{"package":{"name":"mercurial","ecosystem":"PyPI","purl":"pkg:pypi/mercurial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.4.1"}]}],"versions":["0.8.1","0.9","0.9.1","0.9.2","0.9.3","0.9.4","0.9.5","1.0","1.0.1","1.0.2","1.1","1.1.1","1.1.2","1.2","1.2.1","1.3","1.3.1","1.4","1.4.1","1.4.2","1.4.3","1.5","1.5.1","1.5.2","1.5.3","1.5.4","1.6","1.6.1","1.6.2","1.6.3","1.6.4","1.7","1.7.1","1.7.2","1.7.3","1.7.5","1.8","1.8.1","1.8.2","1.8.3","1.8.4","1.9","1.9.1","1.9.2","1.9.3","2.0","2.0.1","2.0.2","2.1","2.1.1","2.1.2","2.2","2.2.2","2.3","2.4.1","2.5","2.5.1","2.5.2","2.6","2.6.1","2.6.2","2.6.3","2.7.0","2.7.1","2.7.2","2.8","2.8.1","2.8.2","2.9","2.9.1","3.0","3.0.1","3.1","3.1.1","3.1.2","3.2","3.2.1","3.2.2","3.2.3","3.2.4","3.3","3.3-rc","3.3.1","3.3.2","3.3.3","3.4","3.4-rc","3.4.1","3.4.2","3.5","3.5-rc","3.5.1","3.5.2","3.6","3.6-rc","3.6.1","3.6.2","3.6.3","3.7","3.7-rc","3.7.1","3.7.2","3.7.3","3.8","3.8-rc","3.8.1","3.8.2","3.8.3","3.8.4","3.9","3.9-rc","3.9.1","3.9.2","4.0","4.0-rc","4.0.1","4.0.2","4.1","4.1-rc","4.1.1","4.1.2","4.1.3","4.2","4.2-rc","4.2.1","4.2.2","4.2.3","4.3","4.3-rc","4.3.1","4.3.2","4.3.3","4.3rc0","4.4","4.4-rc","4.4rc0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-6v56-cpg6-3rpx/GHSA-6v56-cpg6-3rpx.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"}]}
