Moderate severity GitHub Reviewed Published May 17, 2023 in dgraph-io/dgraph • Updated Nov 7, 2023

Package

gomod github.com/dgraph-io/dgraph (Go)

Affected versions

< 23.0.0

Patched versions

23.0.0

Description

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 dgraph-io/dgraph#8323. Dgraph users should upgrade to v23.0.0.

Workarounds

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
