Program Overview

Bunicorn is an automated market-making (AMM) decentralized exchange (DEX) currently on the Binance Smart Chain (BSC) network that supports 2 kinds of liquidity pools:

  • Flexible pools with up to 8 tokens, any weight
  • Stable pools with super low slippage & high capital efficiency for stablecoins

In addition to its DEX, Bunicorn also offers high APY liquidity mining farms with a new NFT reward vesting model. For more information about Bunicorn, you can visit their website at https://buni.finance/.

This bug bounty program covers its smart contracts and its staging site and is focused on the prevention of loss of user funds.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

All web and app bugs must come with a PoC in order to be accepted. All web and app bug reports without a PoC will be rejected with a request for a PoC. Rewards for Smart Contract vulnerabilities are variable based on their exploitability, and other factors deemed relevant by the Bunicorn team. For critical vulnerabilities, the payout is capped at 10% of economic damage.

Payouts are handled by the Bunicorn team directly and are denominated in USD. Payouts are done in USDC. However, for critical smart contract vulnerabilities, up to 80% of the reward may be paid out in BUNI.

Assets in Scope

Only web/app vulnerabilities that directly affect the web/app assets listed in this table are accepted within the bug bounty program. All others are out-of-scope.

Under the Github link, only smart contract vulnerabilities are considered in-scope for the bug bounty program. Testnet contracts are out-of-scope.

  • Congestion and scalability
    • including running out of gas
    • including block stuffing
    • including susceptibility to frontrunning
  • Consensus failures
  • Cryptography problems
    • Signature malleability
    • Susceptibility to replay attacks
    • Weak randomness
    • Weak encryption
  • Susceptibility to block timestamp manipulation
  • Missing access controls / unprotected internal or debugging interfaces

Websites and Apps

  • Remote Code Execution
  • Trusting trust/dependency vulnerabilities
  • Vertical Privilege Escalation
  • XML External Entities Injection
  • SQL Injection
  • LFI/RFI
  • Horizontal Privilege Escalation
  • Stored XSS
  • Reflective XSS with impact
  • CSRF with impact
  • Direct object reference
  • Internal SSRF
  • Session fixation
  • Insecure Deserialization
  • DOM XSS
  • SSL misconfigurations
  • SSL/TLS issues (weak crypto, improper setup)
  • URL redirect
  • Clickjacking (must be accompanied with PoC)
  • Misleading Unicode text (e.g. using right to left override characters)

Out of Scope & Rules

The following vulnerabilities are excluded from the rewards for this bug bounty program:

  • Attacks that the reporter has already exploited themselves, leading to damage
  • Attacks requiring access to leaked keys/credentials
  • Attacks requiring access to privileged addresses (governance, strategist)

Smart Contracts and Blockchain

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Basic economic governance attacks (e.g. 51% attack)
  • Lack of liquidity
  • Best practice critiques
  • Sybil attacks

Websites and Apps

  • Theoretical vulnerabilities without any proof or demonstration
  • Content spoofing / Text injection issues
  • Self-XSS
  • Captcha bypass using OCR
  • CSRF with no security impact (logout CSRF, change language, etc.)
  • Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
  • Server-side information disclosure such as IPs, server names, and most stack traces
  • Vulnerabilities used to enumerate or confirm the existence of users or tenants
  • Vulnerabilities requiring unlikely user actions
  • URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Attacks requiring privileged access from within the organization
  • Feature requests
  • Best practices

The following activities are prohibited by bug bounty program:

  • Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
  • Any testing with pricing oracles or third party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
