{"id":"GHSA-634p-93h9-92vh","summary":"ghas-to-csv vulnerable to Improper Neutralization of Formula Elements in a CSV File","details":"### Impact\n\nThis GitHub Action creates a CSV file without sanitizing the output of the APIs.  If an alert is dismissed or any other custom field contains executable code / formulas, it might be run when an endpoint opens that CSV file in a spreadsheet program.  The data flow looks like this 👇🏻 \n\n```mermaid\ngraph TD\n    A(Repository) --\u003e|developer dismissal, other data input| B(GitHub Advanced Security data)\n    B --\u003e|ghas-to-csv| C(CSV file)\n    C --\u003e|spreadsheet program| D(endpoint executes potentially malicious code)\n```\n\n### Patches\n\nPlease use version `v1` or later.  That tag moves from using `csv` to `defusedcsv` to mitigate this problem.\n\n### Workarounds\n\nThere is no workaround.  Please upgrade to using the latest tag, `v1` (or later).\n\n### References\n\n* CWE-1236 information from [MITRE](https://cwe.mitre.org/data/definitions/1236.html)\n* CSV injection information from [OWASP](https://owasp.org/www-community/attacks/CSV_Injection)\n* CodeQL query for CWE-1236 in Python [here](https://github.com/github/codeql/tree/main/python/ql/src/experimental/Security/CWE-1236)\n* PyPI site for `defusedcsv` [here](https://pypi.org/project/defusedcsv/)\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in this repository [here](https://github.com/some-natalie/ghas-to-csv/issues)\n","aliases":["CVE-2022-39217"],"modified":"2023-11-08T04:10:15.184522Z","published":"2022-09-16T22:06:55Z","database_specific":{"github_reviewed_at":"2022-09-16T22:06:55Z","nvd_published_at":"2022-09-17T00:15:00Z","cwe_ids":["CWE-1236","CWE-74"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/some-natalie/ghas-to-csv/security/advisories/GHSA-634p-93h9-92vh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39217"},{"type":"WEB","url":"https://github.com/some-natalie/ghas-to-csv/issues/19"},{"type":"WEB","url":"https://github.com/some-natalie/ghas-to-csv/pull/20"},{"type":"WEB","url":"https://github.com/some-natalie/ghas-to-csv/commit/d0b521928fa734513b5cd9c7d9d8e09db50e884a"},{"type":"PACKAGE","url":"https://github.com/some-natalie/ghas-to-csv"}],"affected":[{"package":{"name":"some-natalie/ghas-to-csv","ecosystem":"GitHub Actions"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-634p-93h9-92vh/GHSA-634p-93h9-92vh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:L"}]}
