How to Fix CVE-2023-29195

To remediate this vulnerability, upgrade all affected Vitess.io/vitess dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

vitess.io/vitess fixed: 0.16.2 
Upgrade vitess.io/vitess to 0.16.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for vitess.io/vitess

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-29195, inspect your project dependencies for Vitess.io/vitess:

inspect dependencies for vitess.io/vitess

Analyze the terminal output to locate any version of Vitess.io/vitess in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.16.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-703: Improper Check or Handling of Exceptional Conditions, where the product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product. In Vitess.io/vitess, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Users 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. Attempting to view the keyspace(s) will also no longer work. Creating a shard using `vtctldclient` does not have the same problem because the CLI validates the input correctly. ### Patches v16.0.2, corresponding to [0.16.2 on pkg.go.dev](https://pkg.go.dev/vitess.io/vitess@v0.16.2) ### Workarounds - Always use `vtctldclient` to create shards, instead of using VTAdmin - Disable creating shards from VTAdmin using RBAC - 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 ``` % etcdctl --endpoints "http://${ETCD_SERVER}" del /vitess/global/keyspaces/commerce/shards/a/b/Shard ``` ### References https://github.com/vitessio/vitess/issues/12842 Found during a security audit sponsored by the [CNCF](https://cncf.io) and facilitated by [OSTIF](https://ostif.org).
