{"id":"GHSA-wc64-c5rv-32pf","summary":"in-toto vulnerable to Configuration Read From Local Directory","details":"### Impact\n\nThe in-toto configuration is read from various directories and allows users to configure the behavior of the framework. The files are from directories following the XDG base directory specification [1]. Among the files read is `.in_totorc` which is a hidden file in the directory in which in-toto is run. If an attacker controls the inputs to a supply chain step, they can mask their activities by also passing in an `.in_totorc` file that includes the necessary exclude patterns and settings.\n\nRC files are widely used in other systems [2] and security issues have been discovered in their implementations as well [3]. We found in our conversations with in-toto adopters that `in_totorc` is not their preferred way to configure in-toto. As none of the options supported in `in_totorc` is unique, and can be set elsewhere using API parameters or CLI arguments, we decided to drop support for `in_totorc`.\n\n### Other Recommendations\n\nSandbox functionary code as recommended in https://github.com/in-toto/docs/security/advisories/GHSA-p86f-xmg6-9q4x.\n\n### References\n\n[1] https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html\n[2] https://spec.editorconfig.org/\n[3] https://github.blog/2022-04-12-git-security-vulnerability-announced/\n","aliases":["CVE-2023-32076","GHSA-p86f-xmg6-9q4x","PYSEC-2023-63"],"modified":"2026-02-04T04:31:45.728286Z","published":"2023-05-11T20:47:56Z","related":["CVE-2023-32076"],"database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-05-11T20:47:56Z","nvd_published_at":"2023-05-10T18:15:10Z","cwe_ids":["CWE-15","CWE-610"]},"references":[{"type":"WEB","url":"https://github.com/in-toto/docs/security/advisories/GHSA-p86f-xmg6-9q4x"},{"type":"WEB","url":"https://github.com/in-toto/in-toto/security/advisories/GHSA-wc64-c5rv-32pf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-32076"},{"type":"WEB","url":"https://github.com/in-toto/in-toto/commit/3a21d84f40811b7d191fa7bd17265c1f99599afd"},{"type":"PACKAGE","url":"https://github.com/in-toto/in-toto"},{"type":"WEB","url":"https://github.com/in-toto/in-toto/releases/tag/v2.0.0"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/in-toto/PYSEC-2023-63.yaml"},{"type":"WEB","url":"https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html"}],"affected":[{"package":{"name":"in-toto","ecosystem":"PyPI","purl":"pkg:pypi/in-toto"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.0"}]}],"versions":["0.1.1","0.2.0","0.2.1","0.2.2","0.2.3","0.2.3.dev2","0.2.3.dev3","0.2.3.dev4","0.2.3.dev5","0.2.dev3","0.3.0","0.4.0","0.4.1","0.4.2","0.5.0","1.0.0","1.0.1","1.1.0","1.1.1","1.2.0","1.3.0","1.3.1","1.3.2","1.4.0"],"database_specific":{"last_known_affected_version_range":"\u003c= 1.4.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/05/GHSA-wc64-c5rv-32pf/GHSA-wc64-c5rv-32pf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
