CyberRota Analysis
AI-GeneratedThe Klever-Go implementation of the Klever blockchain protocol is vulnerable to a critical flaw that allows crafted split-royalty values to bypass validation checks, leading to the creation of unbacked KLV or other assets during asset transfers, marketplace purchases, or ITO transactions. This vulnerability can result in significant financial losses and undermine the integrity of the blockchain. Organizations utilizing Klever-Go versions prior to 1.7.19 should prioritize immediate updates to mitigate this risk.

Original NVD Description
Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, split-royalty fields decoded in core/kapp/builtInFunctions/utils.go can contain values greater than core.HundredPercent, and core/kapp/kda/create.go and core/kapp/kda/trigger.go sum those values in uint32 accumulators. Crafted values such as two 0x80000000 entries wrap the validation sum to zero and pass CheckValid100Params. Royalty payout paths in core/kapp/accounts/accounts.go, core/kapp/market/market.go, and core/kapp/ito/ito.go then credit each oversized split amount and silently discard a negative remainder, allowing ordinary asset transfers, marketplace purchases, or ITO purchases to create unbacked KLV or other assets. This issue is fixed in version 1.7.19.
