In general, the following vulnerabilities do not correspond to the severity threshold: Vulnerabilities in third-party applications Assets that do not belong to the company Best practices concerns Recently (less than 30 days) disclosed 0day vulnerabilities Vulnerabilities affecting users of outdated browsers or platforms Social engineering, phishing, physical, or other fraud activities Publicly accessible login panels without proof of exploitation Reports that state that software is out of date/vulnerable without a proof of concept Reports generated by scanners or any automated or active exploit tools Vulnerabilities involving active content such as web browser add-ons Most brute-forcing issues without clear impact Denial of service (DoS/DDoS) Theoretical issues Moderately Sensitive Information Disclosure Spam (sms, email, etc) Missing HTTP security headers Infrastructure vulnerabilities, including: Certificates/TLS/SSL-related issues; DNS issues (i.e. MX records, SPF records, DMARC records etc.); Server configuration issues (i.e., open ports, TLS, etc.) Open redirects Session fixation User account enumeration Clickjacking/Tapjacking and issues only exploitable through clickjacking/tapjacking Descriptive error messages (e.g. Stack Traces, application or server errors) Self-XSS that cannot be used to exploit other users Login & Logout CSRF Weak Captcha/Captcha Bypass Lack of Secure and HTTPOnly cookie flags Username/email enumeration via Login/Forgot Password Page error messages CSRF in forms that are available to anonymous users (e.g. the contact form) OPTIONS/TRACE HTTP method enabled Host header issues without proof-of-concept demonstrating clear security impact Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS Content Spoofing without embedded links/HTML Reflected File Download (RFD) Mixed HTTP Content HTTPS Mixed Content Scripts Manipulation with Password Reset Token MitM and local attacks Response manipulations without demonstration of system state change IN SCOPE VULNERABILITIES: Smart Contracts We are looking for evidence and reasons for incorrect behavior of the smart contract, which could cause unintended functionality: Stealing or loss of funds Unauthorized transaction Transaction manipulation Attacks on logic (behavior of the code is different from the business description) Reentrancy Reordering Over and underflows Signature/Nonce manipulation Price manipulation Balance manipulation OUT OF SCOPE VULNERABILITIES: Smart Contracts Theoretical vulnerabilities without any proof or demonstration Old compiler version The compiler version is not locked Vulnerabilities in imported contracts Code style guide violations Redundant code Gas optimizations Best practice issues Vulnerabilities that can be exploited through front-run attacks only Program Rules Avoid using web application scanners for automatic vulnerability searching which generates massive traffic Make every effort not to damage or restrict the availability of products, services, or infrastructure Avoid compromising any personal data, interruption, or degradation of any service Don’t access or modify other user data, localize all tests to your accounts Perform testing only within the scope Don’t exploit any DoS/DDoS vulnerabilities, social engineering attacks, or spam Don’t spam forms or account creation flows using automated scanners In case you find chain vulnerabilities we’ll pay only for vulnerability with the highest severity. Don’t break any law and stay in the defined scope Any details of found vulnerabilities must not be communicated to anyone who is not a HackenProof Team or an authorized employee of this Company without appropriate permission Eligibility and Coordinated Disclosure We are happy to thank everyone who submits valid reports which help us improve the security. However, only those that meet the following eligibility requirements may receive a monetary reward: You must be the first reporter of a vulnerability. The vulnerability must be a qualifying vulnerability Any vulnerability found must be reported no later than 24 hours after discovery and exclusively through hackenproof.com You must send a clear textual description of the report along with steps to reproduce the issue, include attachments such as screenshots or proof of concept code as necessary. You must not be a former or current employee of us or one of its contractor. ONLY USE the EMAIL under which you registered your HackenProof account (in case of violation, no bounty can be awarded) Provide detailed but to-the point reproduction steps AI-generated reports without runable PoC are not accepted under this program. POC's are required to execute on the deployed L1 contracts in testnet Disclosure Guidelines Do not discuss this program or any vulnerabilities (even resolved ones) outside of the program without express consent from the organization No vulnerability disclosure, including partial is allowed for the moment.
