Conflux (CFX) Community has accomplished a big safety improve to handle a vulnerability in its EVM, enhancing the protection of consumer property and reinforcing ecosystem safety.
The Conflux (CFX) Community has efficiently executed a important safety improve, model 2.5, on March 17, 2025, following the invention of a vulnerability in its Ethereum Digital Machine (EVM). This vulnerability was initially recognized by the GraFun staff, in response to Conflux Discussion board.
Background of the Incident
The vulnerability, reported on February 13, 2025, concerned the CREATE2 opcode, which permitted the redeployment of contracts at present addresses, probably resetting their state. This flaw deviated from the usual Ethereum EVM conduct, the place such redeployment is prohibited.
Safety Impression Evaluation
A complete safety affect evaluation revealed that almost all manufacturing facility contracts, like Swappi factories, had been unaffected because of extra deal with battle checks. Nevertheless, Gnosis Protected contracts lacked these checks, posing a danger of state reset and enabling replay assaults on beforehand signed transactions.
The safety evaluation concerned inspecting roughly 30 Gnosis Protected contracts, revealing that whereas most funds had been safe, a minority is likely to be in danger.
Safety Response Course of
Conflux acted swiftly to mitigate the risk by notifying ecosystem companions and facilitating the switch of at-risk property. The safety improve course of concerned a number of phases:
- Vulnerability Repair and Integration Testing: Accomplished by February 21.
- Inside Testnet Improve: Carried out on February 24.
- Public Testnet Improve: Introduced February 25, efficient March 3.
- Mainnet Improve Deployment: Introduced March 3, efficient March 17.
Postmortem Evaluation
The vulnerability stemmed from the Conflux EVM’s authentic code ported from OpenEthereum, which contained deceptive feedback and lacked clear error definitions. These components led to a misunderstanding of Ethereum’s CREATE2 conduct, ensuing within the omission of important checks in Conflux’s implementation.
Bug Bounty Reward
Recognizing the severity of the vulnerability, Conflux awarded the GraFun staff a complete bounty of 60,000 CFX, acknowledging their well timed report and the prevention of potential losses.
Observe-Up Actions and Safety Enhancements
Trying forward, Conflux plans to synchronize with Ethereum EVM options and combine official take a look at circumstances to stop comparable vulnerabilities. This transfer goals to reinforce Conflux’s safety and compatibility with Ethereum’s ecosystem.
The Conflux staff stays devoted to transparency and fast response, guaranteeing the safety of its ecosystem and the safety of consumer pursuits.
