CyberRota Analysis
AI-GeneratedThe vulnerability affects the Klever-Go implementation of the Klever blockchain protocol, specifically in the serialization of account names for Elasticsearch requests, allowing attackers to inject malicious data. This can lead to JSON string corruption, rejection of bulk batches, or unauthorized modifications to documents in Elasticsearch indices. Organizations using versions prior to 1.7.20 should prioritize updating to mitigate potential data integrity and security risks.

Original NVD Description
Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.20, indexer/common.go serializedDataForUpdateAccounts places the attacker-controlled acc.Name value into an Elasticsearch _bulk JSON and NDJSON request without escaping it. The SetAccountName transaction accepts valid UTF-8 account names containing quotes, backslashes, and newlines, and the resulting name is stored in consensus account state. When an indexer processes the account, those characters can break the JSON string, reject a bulk batch, or inject additional bulk actions that create, overwrite, or delete documents in indices writable by the indexer. The persistent state value is replayed by new or historical indexers, and direct access to the indexing host or Elasticsearch port is not required. This issue is fixed in version 1.7.20.
