CyberRota Analysis
AI-GeneratedThe vulnerability affects the Klever-Go implementation of the Klever blockchain protocol, specifically in the handling of BLSPublicKey submissions, which lack necessary validation checks. This flaw can lead to significant network disruptions, including missed consensus rounds and potential halting of the network when a malformed key is introduced. Organizations utilizing versions prior to 1.7.20 should prioritize upgrading to mitigate the risk of operational failures and degraded performance.

Original NVD Description
Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.20, core/kapp/validators/validators.go Register and the runtime validator update path accept a submitted BLSPublicKey without curve, prime-order subgroup, or nonzero validation. When a validator with a malformed key becomes eligible and is selected into a consensus group, MultiSigner.Reset and the corresponding signature verification creation path cannot deserialize the group key and cancel the slot. This causes repeated missed rounds and throughput degradation, and a network whose consensus group equals the eligible validator set can halt completely. Genesis validation is not affected because that path already performs CheckPublicKeyValid. This issue is fixed in version 1.7.20.
