{"id":"GHSA-cq2g-pw6q-hf7j","summary":"Cortex's Alertmanager can expose local files content via specially crafted config","details":"### Impact\n\nA local file inclusion vulnerability exists in Cortex versions v1.13.0, v1.13.1 and v1.14.0, where a malicious actor could remotely read local files as a result of parsing maliciously crafted Alertmanager configurations when submitted to the [Alertmanager Set Configuration API](https://cortexmetrics.io/docs/api/#set-alertmanager-configuration). Only users of the Cortex Alertmanager service using `-experimental.alertmanager.enable-api` or `enable_api: true` are affected.\n\n### Specific Go Packages Affected\ngithub.com/cortexproject/cortex/pkg/alertmanager\n\n### Patches\nAffected Cortex users are advised to upgrade to versions 1.13.2 or 1.14.1.\n\n### Workarounds\nPatching is ultimately advised. Using out-of-bound validation, Cortex administrators may reject Alertmanager configurations containing the `api_key_file` setting in the `opsgenie_configs` section and `opsgenie_api_key_file` in the `global` section before sending to the [Set Alertmanager Configuration API](https://cortexmetrics.io/docs/api/#set-alertmanager-configuration) as a workaround.\n\n### References\n- Fixed Versions:\n   - https://github.com/cortexproject/cortex/releases/tag/v1.14.1\n   - https://github.com/cortexproject/cortex/releases/tag/v1.13.2\n- https://cortexmetrics.io/docs/api/#set-alertmanager-configuration\n\n### For more information\nIf you have any questions or comments about this advisory:\n\n* Open an issue in [cortex](https://github.com/cortexproject/cortex/issues/new/choose)\n* Email us at [cortex-team@googlegroups.com](mailto:cortex-team@googlegroups.com).\n","aliases":["CVE-2022-23536","GO-2022-1175"],"modified":"2023-11-08T04:08:21.294648Z","published":"2022-12-19T21:09:05Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2022-12-19T21:09:05Z","nvd_published_at":"2022-12-19T22:15:00Z","cwe_ids":["CWE-184","CWE-641","CWE-73"]},"references":[{"type":"WEB","url":"https://github.com/cortexproject/cortex/security/advisories/GHSA-cq2g-pw6q-hf7j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23536"},{"type":"WEB","url":"https://github.com/cortexproject/cortex/commit/03e023d8b012887b31cc268d0d011b01e1e65506"},{"type":"WEB","url":"https://cortexmetrics.io/docs/api/#set-alertmanager-configuration"},{"type":"PACKAGE","url":"https://github.com/cortexproject/cortex"},{"type":"WEB","url":"https://github.com/cortexproject/cortex/releases/tag/v1.13.2"},{"type":"WEB","url":"https://github.com/cortexproject/cortex/releases/tag/v1.14.1"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2022-1175"}],"affected":[{"package":{"name":"github.com/cortexproject/cortex","ecosystem":"Go","purl":"pkg:golang/github.com/cortexproject/cortex"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.14.0"},{"fixed":"1.14.1"}]}],"versions":["1.14.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-cq2g-pw6q-hf7j/GHSA-cq2g-pw6q-hf7j.json"}},{"package":{"name":"github.com/cortexproject/cortex","ecosystem":"Go","purl":"pkg:golang/github.com/cortexproject/cortex"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.13.0"},{"fixed":"1.13.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-cq2g-pw6q-hf7j/GHSA-cq2g-pw6q-hf7j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
