Detailsinfo

A vulnerability classified as problematic has been found in Dgraph up to 22.x. Affected is an unknown function of the component Audit log Handler. The manipulation with an unknown input leads to a inadequate encryption vulnerability. CWE is classifying the issue as CWE-326. 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. This is going to have an impact on confidentiality. CVE summarizes:

Dgraph is an open source distributed GraphQL database. Existing Dgraph audit logs are vulnerable to brute force attacks due to nonce collisions. The first 12 bytes come from a baseIv which is initialized when an audit log is created. The last 4 bytes come from the length of the log line being encrypted. This is problematic because two log lines will often have the same length, so due to these collisions we are reusing the same nonce many times. All audit logs generated by versions of Dgraph <v23.0.0 are affected. Attackers must have access to the system the logs are stored on. Dgraph users should upgrade to v23.0.0. Users unable to upgrade should store existing audit logs in a secure location and for extra security, encrypt using an external tool like `gpg`.

The weakness was published 05/18/2023 as GHSA-92wq-q9pq-gw47. The advisory is shared for download at github.com. This vulnerability is traded as CVE-2023-31135 since 04/24/2023. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.

Upgrading to version 23.0.0 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
