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fraud activities Publicly accessible login panels without proof of exploitation Reports that state that software is out of date/vulnerable without a proof of concept Reports generated by scanners or any automated or active exploit tools Vulnerabilities involving active content such as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 OUT OF SCOPE: MOBILE VULNERABILITIES Attacks requiring physical access to a user's device Vulnerabilities that require root/jailbreak Vulnerabilities requiring extensive user interaction Exposure of non-sensitive data on the device Reports from static analysis of the binary without PoC that impacts business logic Lack of obfuscation/binary protection/root (jailbreak) detection Bypass certificate pinning on rooted devices Lack of Exploit mitigations i.e., PIE, ARC, or Stack Canaries Sensitive data in URLs/request bodies when protected by TLS Path disclosure in binary OAuth & app secret hard-coded/recoverable in IPA, APK Sensitive information retained as plaintext in the device’s memory Crashes due to malformed URL Schemes or Intents sent to exported Activity/Service/Broadcast Receiver Any kind of sensitive data stored in-app private directory Runtime hacking exploits using tools like but not limited to Frida/Appmon (exploits only possible in a jailbroken environment) Shared links leaked through the system clipboard Any URIs leaked because a malicious app has permission to view URIs opened. Exposure of API keys with no security impact (Google Maps API keys etc.) Reports that bypass rate limiting through changing of IP addresses/Device IDs Address bar/URL/domain spoofing in dApp browser Reports with mobile versions not downloaded from official sites listed in our scope 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.
