Rewards will be provided according to the rules of this bug bounty program as outlined above. At the discretion of Coin98, quality, creativity, or novelty of submissions may modify payouts within a given range.

In case of multiple reports about the same issue, Coin98 will reward the earliest submission, regardless of how the issue was reported.

CVSS standards will be used for vulnerability rating(CVSS3.1).

  • Critical severity vulnerabilities will have a significant impact on the security of the project, and it is strongly recommended to fix the critical vulnerabilities.
  • High severity vulnerabilities will affect the normal operation of the project. It is strongly recommended to fix high-risk vulnerabilities.
  • Medium severity vulnerability will affect the operation of the project. It is recommended to fix medium-risk vulnerabilities.
  • Low severity vulnerabilities may affect the operation of the project in certain scenarios. It is suggested that the project team should evaluate and consider whether these vulnerabilities need to be fixed.

IN-SCOPE VULNERABILITIES (WEB, MOBILE)

  • We are interested in the following vulnerabilities:
  • Business logic issues
  • Payments manipulation
  • Remote code execution (RCE)
  • Injection vulnerabilities (SQL, XXE)
  • File inclusions (Local & Remote)
  • Access Control Issues (IDOR, Privilege Escalation, etc)
  • Leakage of sensitive information
  • Server-Side Request Forgery (SSRF)
  • Cross-Site Request Forgery (CSRF)
  • Cross-Site Scripting (XSS)
  • Directory traversal
  • Other vulnerability with a clear potential loss

OUT OF SCOPE: WEB VULNERABILITIES

  • Vulnerabilities found in out of scope resources are unlikely to be rewarded unless they present a serious business risk (at our sole discretion). 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  • Reports that state that software is out of date/vulnerable without a proof of concept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 that 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/tap jacking
  • 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 the vulnerability
  • 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

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 anaries
  • Sensitive data in URLs/request bodies when protected by TLS
  • Path disclosure in the 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 (exploiting these for sensitive data leakage is commonly in scope)
  • 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.)
  • Rewards or recognition require that the Coin98 security team can reproduce and verify an issue and that the security impact is clear;
  • Reproduction steps need to be clear, and may include screenshots, videos, scripts, etc;
  • Do not conduct social engineering and phishing to people;
  • Do not leak the details of the vulnerability;
  • Do not use a scanner for large-scale scanning. If the business system or network becomes unavailable, it will be handled according to relevant laws;
  • Those who test the vulnerability should try to avoid modifying the page directly, continuing poping up the message box (log is recommended for XSS verification), stealing Cookies, and obtaining aggressive payload such as the user information (for blind XSS testing, please use DNSLog). If you accidentally used a more aggressive payload, please delete it in time;
  • Vulnerability testings are only limited to PoC(proof of concept), and destructive testings are strictly prohibited. If harms are caused inadvertently during the testing, it should be reported in time. Meanwhile, sensitive operations performed in the test, such as deletion, modification, and other operations, are required to be explained in the report.

  • 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

  • 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.
  • Please do NOT publish/discuss bugs
