{"id":"GHSA-pqj7-jx24-wj7w","summary":"VTAdmin users that can create shards can deny access to other functions","details":"### Impact\nUsers can either intentionally or inadvertently create a shard containing `/` characters from VTAdmin such that from that point on, anyone who tries to create a new shard from VTAdmin will receive an error. \nAttempting to view the keyspace(s) will also no longer work.\nCreating a shard using `vtctldclient` does not have the same problem because the CLI validates the input correctly.\n\n### Patches\nv16.0.2, corresponding to [0.16.2 on pkg.go.dev](https://pkg.go.dev/vitess.io/vitess@v0.16.2)\n\n### Workarounds\n- Always use `vtctldclient` to create shards, instead of using VTAdmin\n- Disable creating shards from VTAdmin using RBAC\n- Delete the topology record for the offending shard using the client for your topology server. For example, if you created a shard called `a/b` in keyspace `commerce`, and you are running etcd, it can be deleted by doing something like\n```\n% etcdctl --endpoints \"http://${ETCD_SERVER}\" del /vitess/global/keyspaces/commerce/shards/a/b/Shard\n```\n\n### References\nhttps://github.com/vitessio/vitess/issues/12842\n\nFound during a security audit sponsored by the [CNCF](https://cncf.io) and facilitated by [OSTIF](https://ostif.org).","aliases":["CVE-2023-29195"],"modified":"2023-11-01T05:01:47.503880Z","published":"2023-05-11T19:40:49Z","database_specific":{"github_reviewed_at":"2023-05-11T19:40:49Z","nvd_published_at":"2023-05-11T20:15:09Z","cwe_ids":["CWE-20","CWE-703"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/vitessio/vitess/security/advisories/GHSA-pqj7-jx24-wj7w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29195"},{"type":"WEB","url":"https://github.com/vitessio/vitess/issues/12842"},{"type":"WEB","url":"https://github.com/vitessio/vitess/pull/12843"},{"type":"WEB","url":"https://github.com/vitessio/vitess/commit/9dcbd7de3180f47e94f54989fb5c66daea00c920"},{"type":"PACKAGE","url":"https://github.com/vitessio/vitess"},{"type":"WEB","url":"https://github.com/vitessio/vitess/releases/tag/v16.0.2"},{"type":"WEB","url":"https://pkg.go.dev/vitess.io/vitess@v0.16.2"}],"affected":[{"package":{"name":"vitess.io/vitess","ecosystem":"Go","purl":"pkg:golang/vitess.io/vitess"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.16.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/05/GHSA-pqj7-jx24-wj7w/GHSA-pqj7-jx24-wj7w.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L"}]}
