How to Fix CVE-2023-31135

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

github.com/dgraph-io/dgraph fixed: 23.0.0 
Upgrade github.com/dgraph-io/dgraph to 23.0.0
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 github.com/dgraph-io/dgraph

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-31135, inspect your project dependencies for Github.com/dgraph io/dgraph:

inspect dependencies for github.com/dgraph-io/dgraph

Analyze the terminal output to locate any version of Github.com/dgraph io/dgraph in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 23.0.0), 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-326: Inadequate Encryption Strength, where the product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. In Github.com/dgraph io/dgraph, 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 Existing Dgraph audit logs are vulnerable to brute force attacks due to nonce collisions. All audit logs generated by versions of Dgraph <v23.0.0 are affected. ### Patches This issue was patched in https://github.com/dgraph-io/dgraph/pull/8323. Dgraph users should upgrade to v23.0.0. ### Workarounds Store existing audit logs in a secure location. For extra security, encrypt using a tool like `gpg`. ### References See https://github.com/dgraph-io/dgraph/pull/8323 for more context on the vulnerability.
